I opened up the large dome to gather more data on M77 and it's supernova, a repeat of Sunday evening with intermittent cloud despite a decent forecast. After the Christmas meal I showed fellow member Paul around the big dome and then opened up the small dome and we viewed Betelgeuse and Sirius through Geraldine, Sirius was very low and displayed a fantastic range of colours. I closed down around 23:00.
