News - 13th December

Geminid meteor watching: With temperatures falling to -4 and before the waning Gibbous Moon rose, groups of Staff, Friends, external visitors and families gathered from 8pm till 11.15pm under largely clear skies. Over 50 people took part and rates of Geminids climbed from 20 an hour to 30 then over 50. At the end there was a minute in which 8 were seen. In total over 159 were recorded and well over 160 seen. The meteors were fairly uniform with most at magnitude +1 but a few bright and unusual meteors were seen. The Binos allowed a good view of M42 (Pleiades) and the 10 inch tracked first M45 (Orion Nebula) and then Jupiter seen for the first time in the evening this autumn. Intially only 3 moons were visible but soon all four, unusually Io was the furthest out apparently. M31 was found by eye and Constellations identified
