The Comet is best found by sweeping up the right side of Orion towards the Pleiades with wide angle low magnification binoculars. It is a grey smudge and quite large (0.3 degrees) and hence diffuse. It is moving so fast against the background that using a telescope and inputting coordinates is not easy. Though it has passed its closest approach to the Earth it wont reach perihelion till 14th February. As it recedes from us its magnitude will fade quickly as it climbs highr in the sky through Taurus (passing close to the Pleaides on Friday and Saturday) and Aries. It is visible by eye over the next couple of weeks (best using averted vision) if away from light polution. Photography and image staking is needed to see its tail<br.

• On Saturday there is the possibility of a rare flare up of the Draconid meteor shower. The Draconids are caused by dust from comet 21P-Giocobini-Zimmer a short period (6.5 year)comet. Occasionally the Earth passes through denser dust streams and on Saturday we will encounter the 1900, 1907 and 1980 streams. Draconid (or Giocobinid) metoers are faint and slow, but rates have reached 1000s an hour in the past (1933 and 1946). This year’s forecast is for a couple of peaks at 8pm and 9pm, perhaps reaching 10 meteors a minute. These could however occur anytime from 4pm till 10pm local time. Sunset is at 6.30pm and the waxing Gibbous three-quarter lit Moon rises at 5pm and its light will affect the number seen. The Radiant in Draco is NW from UMa and UMi and looking North away fromm the Moon will probably be best. If the evening is not clear, you can listen to the ‘ping’ of incoming meteors on www.spaceweatherradio.com

Week of 3rd January 2011.

 

• The new year starts with a flurry of astronomical events. On Monday night the Quadrantid meteor shower peaks. The Quadrantids are one of the least well known showers and yet now the second best in the year. The shower is named after the radiant in the now redistributed old constellation of Quadrans Muralis (the mural quadrant) and now is placed in Bootes, just above the end of the handle of the Saucepan (Plough). The shower is caused by object 2003 EH1 an asteroidal (or dead comet) body with a 5.5 year orbit. Quadrantids are slow meteors and often coloured and bright. The peak is narrow (one hour only) and is forecast around 00.00hrs. With no Moon this is very favourable and over 120 per hour are forecast. It is worth looking out for early meteors from Sunday. If cloud prevents visual sightiongs, you can hear the Quadrantids as they enter the atmosphre via their RADAR signal (you hear a ‘ping’ on www.spaceweatherradio.com.
• The Sun rises on Tuesday morning in partial eclipse. From here it should be visible about 67% eclipsed at 8.13am (sunrise) and the final contact at the end of the eclipse occuring at 09.36 UT. ON NO ACCOUNT SHOULD YOU LOOK DIRECTLY AT THE SUN WITH OPTICAL INSTRUMENTS OR EVEN BY EYE ALONE (ONLY OFFICIAL SOLAR GOGGLES OR SOLAR FILTERS ARE SAFE). It is possible with care to project the eclipsed Sun through a hole (a couple of mm in a piece of cardboard) onto a piece or cardboard. But always face away from the Sun.
• Astronomical twilight ends at 18.13 UT at the start of the week and 18.20 UT at the end.

• Astronomical twilight ends at 18.04UT at the start of the week and 18.08UT at the end
• The Moon is waxing and will be First Quarter on Thursday
• The Sun at last has an easily visible sunspot group number 1035

Week of 14th December

 

• Astronomical twilight ends at 18.02UT at the start of the week and 18.04UT at the end
• The Moon is New on Wednesday and should be visible as a slender crescent in the West on Friday
• The Sun has one small cycle 24 sunspot number 1034
• Mars is becoming ever more prominent bright red in the NE sky rising late evening. It appears to change direction on Wednesday and night by night moves backwards (retrograde) against the background stars. This is due to the Earth undertaking it in its orbit. Thus Mars will move from Cancer into Leo and then back again. It is closest in January, however this coincides with it being furthest from the Sun in its elliptical orbit, so it will not appear as large as in 2003 for example
• There are no evening ISS passes this week but there are 2 super bright Iridium flares to watch out for: On Tuesday at 17.58.46 at 51 degrees altitude in NE and Wednesday at 17.52.37, 53 degrees altitude in NE

 

Week of 7th December

 

• Astronomical twilight ends at 18.02UT at the start of the week and at 18.02UT at the end. In fact its earliest value of 18.01UT is reached mid-week, despite being some 2 weeks before the Solstice
• The best meteor shower of the year with predictions of 100-150 per hour, the Geminids, peak in the early hours of 14th December (though tend to be visible from 7th to 16th). Next Sunday night will thus be ideal viewing. Gemini is now well above the horizon in the NE evening sky and the radiant is just above Castor (top of the 2 bright stars at the Northern end of the constellation) The Geminid shower is unusual in that its origin is not cometary and it is a recent shower with the first reports being in 1862, making it nicely contemporary with the Marlborough telescope! The debris streams come instead from an asteroid 3200 Phaethon (this link only being made in 1983) which has a 1.4 year orbit. This gives the meteors a different quality, in that they tend to be slow and are often bright due to the more variable particle sizes. Fingers crossed for clear skies
• The Moon is Last Quarter on Wednesday and new at the start of next week, perfect for the Geminids
• The Sun is blank again
• There are no evening ISS passes or bright iridium flares this week

This Friday NASA released images from the current Lunar Reconnaisance Orbiter showing the landing sites and bases of the landers of the Apollo missions for the first time, even the footprint track across the surface..we realy did go there !! (sorry conspiracy theorists!) see http://www.nasa.gov/mission_pages/LRO/multimedia/lroimages/apollosites.html. The Apollo program cost $25.4 billion at the time, which is nearly $150 billion in current dollars. There were six landings, but man has not been to the Moon since December 1972. Michael Collins talking this week said, “I really believe that if the political leaders of the world could see their planet from a distance of 100,000 miles their outlook could be fundamentally changed,” Collins said. “That all-important border would be invisible, that noisy argument silenced. The tiny globe would continue to turn, serenely ignoring its subdivisions, presenting a unified facade that would cry out for unified understanding, for homogeneous treatment. The Earth must become as it appears: blue and white, not capitalist or communist; blue and white, not rich or poor; blue and white, not envious or envied.” One of the key words Collins uses to describe Earth is “fragile” and he said that 40 years later it is still fragile “and growing more so.” “When we flew to the Moon, our population was 3 billion; today it has more than doubled and is headed for 8 billion, the experts say. I do not think this growth is sustainable or healthy. The loss of habitat, the trashing of oceans, the accumulation of waste products – this is no way to treat a planet.”

This year the shower is very well placed at New Moon. The official peak is at 3am on Monday 13th, but good rates can often beseen on days either side of this, so look out (by naked eye) as the weather allows.

• Mercury reached greatest elongation (angle from the Sun) on 2nd and will remain a good target for naked eye observation low on the NW horizon after sunset. Venus reaches greatest elongation next Saturday and both Venus and Mercury are now seen in Gemini. Venus is nicely alligned with Castor and Pollux at the start of the week and Saturn in Leo adds to the other two showing the plane of the Solar System (the Ecliptic) and the Zodiac constellations of Leo, Cancer and Gemini (with the Sun in Taurus..note not Gemini, for those who read their ‘stars’ in the papers!)
• The Sun has a new active region (spot 960) emerging on its eastern limb
• The ISS returns this week with evening passes as follows: Tuesday at 00.09.26 WSW to E and 22.55.34 SW to E. Wednesday at 00.30.14 W to E and 23.16.09 WSW to E.

• There is one bright Iridium flare on Friday at 22.23.14, 45 degrees altitude in NE
• The ISS makes good passes this week and in good instruments will be seen to be lareger as shuttle Atlantis is docked. After the mission it will remian larger as they are unfolding new Solar panels. The Space Staition can be seen best: On Monday at23.24.01 from W to E. Tuesday 22.09.43 W to E and 23.44.41 W to SE. Wednesday at 22.30.22 W to ESE. Thursday 22.51.00 W to ESE

 

Week of 28th May

 

• The Moon will be Full (Rose Moon) on Friday, when it will be within a few degrees of Jupiter and Antares
• Vesta reaches opposition and brightest magnitude on Wednesday, but still needs a dark sky for the unaided eye.

• This is the month for the best viewing this year of the 77% illuminated planet Mercury. Though it will be dimming, its angle from the Sun is increasing into June. On Thursday, the 2 day old Moon will be just North of the planet and on Friday should be half-way between Mercury and Venus (waning to about 60% illumination) in a line at 9pm. If the evenings are clear, Mercury should be easy to spot around 10 degrees altitude, but do not scan with instruments until the Sun has set.
• The Sun has a decaying spot but is nearly blank again
• Very unusually an asteroid (Vesta) brightens to naked-eye visibility and the next week or so over the New Moon is ideal. Vesta is a couple of degrees higher than Jupiter in the late evening SE sky in Ophiucus and forms a triangle with Jupiter and Antares.
• There is a comet (Lovejoy) passing through Draco at the start of the week and on 14th will be found next to eta Draconis (2nd mag. star), it is not visble to the naked eye but easy in good binoculars

However, the transit can be seen on various websites including the SOHO site (see Links). The transit begins at 19.11 GMT and ends at 00.15 GMT on 9th. Note: The next visible transit will be the much rarer transit of Venus (seen in total in 2004) on 6th June 2012, but this will only be seen at the end for the 1st hour of daylight from 5 till 6 am local time
• TThe Moon will wane during the week to Last Quarter next week-end. Whilst these clear and misty nights are common, look out fro Lunar Halos and other rainbow effects caused by water and ice particles at high altitude

• Thursday 24th will see the vote by the IAU as to whether we change from a 9 Planet Star (Solar) System to one of 12 (with perhaps more to follow). Friday 25th: The IAU have now voted and have agreed an 8 Planet System, so Pluto has been demoted to a Dwarf Planet with Ceres, UB 313 and potentially many more Trans Neptunian Objects. The critical definition is that a Planet must reign supreme in its neighbourhood ie ‘clearing’ all similar objects, Pluto fails in this respect
• Please note that contrary to articles in some areas of the Press, the planet Mars will not be unusually close and large on 27th, it is in fact at the far side of its orbit and close to the Sun in the sky. This is an Internet generated hoax

This may herald the start of cycle 24 which is predicted to be more active than anything seen in the last 50 yeras (peaking around 2011)
• On 24th August the IAU will vote on a new classification for planets and other Solar System objects, this is likely to confirm the planetray status of Pluto (though as a double planet with Charon) and also to elevate the newly discovered 2003 UB313 and also Ceres to planetary status making the Solar System a 12 planet system. The eccentric and inclined orbit objects will be called Plutons, other objects will be called Small Solar System Bodies and the term Minor Planet is to be dropped
• The ISS is back and evening passes are visible as follows: On Friday 18th at 22.05.54 from SW to SSE reaching 36 degrees altitude and on Saturday at 22.27.55 from WSW to SSE reaching 62 degress altitude. Visible passes will continue through next week

• Our clocks revert to GMT(UT) ie 1 hour back at 1am next Sunday 30th

 

Week of 17th October

 

• The Moon is full on Monday (Hunter or Blood Moon). It will be partially eclipsed as well but this is not visible from here. We are entering Major Lunar Standstill season (this was an important marker in the calendars of the ancient (especially coastal dwelling) astronomers) and in December the full Moon will reach its highest point above the local horizon here, 67 deg. Even now the Moon will appear very high in the night sky.

Week of 10th October

 

• The Moon is First Quarter on Monday
• There is a chance of increased meteor activity from 8th till 10th this year. These are the Draconids (for a long time a minor shower) but they have reached storm proportions in the past and may do this year. The radiant is in Draco (to the West of Polaris and NW of Plough). These meteors are associated with the short period comet Giacobini-Zinner whose orbit is severely perturbed by regular close encounters with Jupiter
• The Sun is quiet with one small spot
• Mars is rapidly reaching its full glory as seen in 2003 and will be the best for the next 15 years by the end of the month. It has come 56 million miles closer to us since July this year. Many features are becomming visible in the 10 inch.
• There are no ISS evening passes his week, but this is a good week for Iridium flares; On Sunday (9th)at 20.17.46 33 deg. altitude in N, Monday at 20.11.33 35 deg. alt in N, Tuesday 20.05.21 37 deg. alt in N, Wednesday 19.59.11 39 deg. alt in NNE, the best is on Thursday at 19.52.59 41 deg. alt in NNE, Friday at 19.46.49 42 deg. alt in NNE and Saturday at 19.40.39 44 deg. alt in NNE.

Week of 26th September

 

• The Sun is now quiet and little activity is expected
• The Moon continues to wane and will be New on Monday 3rd and in exact line with the Sun. The Solar Eclipse produced will not be total due to the Moon being further from the Earth in its orbit and hence it will only block the centre of the Sun’s disc, producing a ring of photosphere at maximum (annular eclipse) this effect will be visible from Spain and North East Africa. From here we will see a partial eclipse (starting at 8.50am local time) where 67% (around 9.45am) of the Sun’s disc will be covered, the eclipse will end at 11.20am. This is the greatest partial eclipse extent visible from here till 4th January 2011.
• The lack of Moon this week will again prove beneficial in viewing the outer planets and getting a good view of the suraface details on Mars; the southern polar ice cap is not so evident as in 2003 as its shrinks into Summer, but clouds over the growing northern cap can be made out in the 10 inch.

Week of 12th September

 

• The Sun will remain highly active as spot 798 rotates to face the Earth. 9 large flares have now been detected since last Wednesday. The potential for disruptive magnetric storms and low-latitude auroras is very high, look out on the night of 14th and 15th if clear. A flare on 13th sent a Coronal Mass Ejection towards Earth. This has been the most active month since 1991 ! and we are nearly at Solar minimum
• The Moon will be full next Sunday, this is the Harvest Moon

Apology: ISS times and Iridium times have been given in GMT, this was not clear and they will now be given consistently in Local time.

 

Week of 22nd August

 

• The Moon will be last Quarter on Friday and the loss of Moonlight will allow better viewing of the outer planets at the end of the month
• Mercury is at greatest elongation on Tuesday and Mars is just south of the Moon on Thursday
• The Sun currently has a fast growing spot group 5 times the Earth in size and the days ahead will see some activity towards the Western limb

The impact will hopefully lead to an increased knowledge of the composition and of the early Solar System. It will also demonstrate our ability to impact an approaching comet, though the change in this comet’s path will be negligable. The event will not be visible from the UK. Incidently the impactor, which will be vaporised carries a CD inscribed with the names of 14 GCSE Astronomers from the College (Class of 2004)

Week of 7th March

 

• This week in 1934 Yuri Gagarin was born.
• The I.S.S. will be making passes this week. The following are bright evening events. Friday at 19.45.33 from WSW up to 56 deg altitude to SE (3 minutes) and Saturday 19.06.11 WSW to 62 deg to E (5 minutes).

• The Sun is still quiet.
• The Moon is now waning and will be New on Thursday

• Mercury is easily visible at sunset low in the West, near the crescent Moon on 11th

 

Week of 28th February

 

• This week in 1966 Venera 3(USSR) was the first probe to reach Venus and in 1972 Pioneer 10 was launched to Jupiter
• Having seen my first Iridium flare last week, I think they are worth looking out for if the sky is clear. The following are bright flares for this week (all data from heavens-above.com)on 28th at 16.13.38, 83 deg altitude and bearing 184 deg (S) on 2nd at 18.06.12, 64 deg bearing 12 deg (NNE) on 3rd at 18.00.05, 66 deg bearing 14 deg (NNE) and on 4th at 19.59.52, 27 deg bearing 8 deg (N). These are angles as from Marlborough. The flares are caused as various rotating Iridium communications satellites catch the Sun light in their orbits and due to their flat door shaped reflecting surfaces they can shine as bright as the Moon, typical flares last for 1 or 2 seconds.
• The long filament on the Sun’s surface is now visible as a prominence above the western limb but the Sun remains relatively inactive.
• The Moon is waning to last Quarter on Thursday.

 

Week of 21st February

 

• This week in 1962 John Glenn became the first American Astronaut to orbit the Earth.
• There will be an Iridium Flare visible in daylight from Marlborough at 14.33.11 on Thursday 24th. Look SSW (192 deg.) and at 52 deg. altitude
• The Sun has only mature spots and is quiet. However an enormous loop of gas is suspended above the Sun’s surface facing us and appears as a dark filament, it is equivalent to the Earth-Moon distance in length.
• The Moon will be full on Thursday (Snow Moon), its name may well be appropriate this week if the forecasts are correct.
• Saturn is rather washed out by the Moonlight this week and Jupiter is still a middle of the night target.

 

Week of 14th February

 

• This week marks two historic birthdays, Copernicus in 1473 and Galileo in 1564. Valentine’s Day in 2001 marked the first pictures being sent back from the surface of an Asteroid (Eros)
• The Sun is relatively quiet at present and spot 720 has all but disappeared.
• The Moon in waxing to 1st Quarter on Wednesday and is presently showing clear Earth-shine on the dark hemisphere.
• Comet Machholz is now barely discernable by eye, but is still ok in Binos. It is now high in the North-Western sky half way between Cassiopeia and the Pole Star, being close to the pole it is harder to follow with the Earth’s rotation.
• For those with telescopes Saturn is very close (just to the left) to the Eskimo Planetary nebula and look out (by unaided eye) for the pretty Beehive Open Cluster (M44) about 15 degrees below Saturn in Cancer.

 

Week of 7th Febrauary

 

• This week in 1999 the NASA probe Stardust was launched. It successfully collected samples from within 250km of the nucleus of Comet P/Wild 2 at the end of 2003. The samples will be returned to Earth on January 15th 2006. The hope is that there may be signs of biological molecules.
• Recently discovered 320m wide Asteroid 2004 MN4 will pass the Earth in 2029 on April 13th at a distance of only 30,000km and will be as bright as a 3rd magnitude star..something to look forward to !
• Sunspot 720 is looming on the Sun’s eastern limb and may bring a significant rise in Solar activity over the next few days.
• The Moon will be New on Tuesday.
• All week will be good for Comet Machholz in Binos, if we get a clear night !.

 

Week of 31st January

 

• This week two years ago Space Shuttle Columbia broke up on reentry killing all 7 on board. In 1974 the probe Mariner 10 took the first close up images of Venus
• The Moon is now waning and will be new by the start of next week.
• The Sun is presently quiet but spot 720 may well return by the middle of the next week
• Comet Machholz though now at the limit of naked eye visability is still clear in Binos and with the lack of Moon this week and given its high altitude (next to the W of Cassiopeia) it is not badly affected by scattered light

 

Week of 24th January

 

• This week marks the 19th anniversary of 2 major astronomical events. In 1986 Voyager 2 became the first space probe to pass by Uranus and later that week the Challenger Space Shuttle blew up on take off killing all 7 crew.
• The Moon will be full on Monday night (Wolf Moon)
• The vast sunspot 720 has gone round the western limb and the Sun is now quiet, but the spot may still be in existense when the Sun has made another half rotation

 

Week of 17th January

 

• The Moon is waxing throughout the week and will be full on 25th.
• Saturn is well placed for viewing at present and showing plenty of detail in the 10 inch.
• Comet Machholz continues to head higher in the sky towards H and Chi Perseii (Double Open Cluster)and is fading in brightness.
• The Sun has released 2 Coronal Mass Ejections over the week-end and spot 720 is now bigger than Jupiter. High magnetic activity is expected with chances of Aurorae at the start of the week.

 

Week of 10th January

 

• On Thursday the NASA Deep Impact mission is launched. This is the first mission to aim to impact a comet’s nucleus (Temple 1) to reveal what it is made of and to release material which will shed light on the early Solar Sustem. On Friday the ESA Huygens probe will descend into the atmosphere of Titan, the largest moon of Saturn and hopefully reveal one of the greatest mysteries of the Solar System, the moon’s composition.
• Monday 10th is a New Moon which will wax to first quarter by the end of the week. If the forecast is correct there could be some clear dark skies during the week (Tuesday and Wednesday)
• Comet Machholz is now past the Pleiades and heading up towards Perseus. It will remain a naked-eye object till next week.
• Saturn will be at opposition on Thursday and thus well placed for observation.
• The Sun has suddenly grown a very large sunspot (visble to the unaided eye, but don’t look directly at the Sun !) This could give rise to increased Solar activity.

 

Week of 3rd January

 

• Monday 3rd the Quadrantids meteor shower peaks at 12.20 pm. There should be meteors visible on Monday and Tuesday nights. The radiant is between the Pole star and the tail of the Plough (The constellation Quadrans Muralis is now no longer recognised)
• Comet Machholz is now brightening to its maximum by the end of the week and will be only 2 degrees from the Pleiades Open cluster on Friday 7th. It is now distinctly green in colour (due to Carbon and CN in its coma) Its straight ion tail is now visible in the telescope and the dust tail, but this is very faint. If the night is clear, the comet and its ion tail are easy now by unaided eye.
• Saturn will be only 7 degrees from Pollux on 6th.
• The Sun has now quietened down and its disc is almost blank.
