News - 31st January

House visit: 10 pupils from TU Shell came up to the Dome in high winds but at least no rain

Next House visit: Sunday 7th February (EL)

21st January

External visit: Some 26 Friends of Swindon Museum and Art Gallery visited for a double evening combining a visit to 'In the Marlborough Night Garden' with Gavin James and then a trip to the Observatory. Sadly the sky had clouded and only the Moon occasionally got through the cloud. Before the groups came up the sky was clear and Comet Catalina had been located in the 10 inch and a drawing made showing it close to a 9th magnitude star in Draco, several degress away from its position on Tuesday

19th January

Comet spotting: A clear night at last and the chance to see Catalina. The 10 inch found it straight away with coordinates input. Finding it in the binos was harder and needed the old technique of finder charts, A small group of Friends and staff gathered in advance of the GCSE observing session. The 9-10 day old waxing Gibbous Moon really washed out the sky and the Comet was not much more than a faint blur. Some assymetry was visible suggesting tails. Seen against a couple of faint stars the motion was perceptable over 3 hours and was estimated to be 1-2 arc minutes. It was good to be visited by a couple of past GCSE astronomers too

GCSE Observing: 10 Remove astronomers came up, some not in very warm clothes as temperatures dropped to -5 degrees. Constellaon drawings were completed. Sadly the Moon was very close to Orion, Only one Hundred astronomer appeared and managed 3 Messier drawings though again the mMoon rendered M42 and M45 less than perfect

17th January

House visit: 11 Shell pupils from BH came up to the Dome. It was cloudy

Next house visit: Sunday 31st January (TU)

Astrophotography exhibition: Some 60 Friends and visit0rs attended the private viewing of Gavin James' 'In the Marlborough Night Garden'. A stunning array of 17 images taken with modest equipment from his garden in central Marlborough
