28th June

Radcliffe Society: The final meeting of the year took place on Zoom. A number of Shell pupils who will be studying Astronomy GCSE next year also attended. GKWJ gave a What’s Up that highlighted observing opportunities throughout the summer. CEB spoke about noctilucent clouds and JAG gave a Latest News update, with mention of recent research developments on the dimming of Betelgeuse and the Cosmic Dawn. Next meeting will be in September

23rd June

Remove Physics visit: On the first opportunity to see shadows since the Solstice, CEB was joined by a Remove Physics set at the Dome. Measurements of shadow lengths were made at local noon (1pm). These measurements were fed into the National Schools Observatory Solstick website and, knowing the length of the dowling rod used, gave each pupil their own estimate for the circumference of the Earth (out by only 1000km in most cases) in a repeat of the famous Eratosthenes experiment of 3rd Century BC

16th June

Upper Sixth visit: An U6 girl, who was new in the L6 and her HM (IV) came up to the Dome for a tour and to do some solar observing. The mature sunspot 2833 was visible in the Solarscope and well viewed in the ETX and 10 inch with its sunflower-like penumbra

11th June

Upper Sixth visit: 2 U6 girls, who had arrived at the College in the L6 and never visited the Dome, asked for a tour of the observatory with CEB. They were able to view the Solar disc in goggles, a solarscope, the ETX with white light filter and the 10 inch with white light filter, where, though the disc was devoid of sunspots, the photosphere granulation could be clearly seen

10th June

Partial Solar Eclipse: The sky was largely cloudy throughout the eclipse, but a small break in cloud at around 11.30am allowed several of the Remove astronomers to see the edge of the Moon using solar goggles and even take a couple of mobile phone images. GKWJ manged to get a super H alpha shot from his River Park Observatory (see solar section in Images)

9th June

GCSE revision lesson: The Remove astronomy set joined CEB for a revision lesson outsde the Dome. The sky was clear and the sunspot group 2829 viewed in the 10 inch. The College had a film crew on site, so they were able to use some of the pupils in their PR shots
