In spite of the weather being largely dominated by high pressure last night was the first clear night since the beginning of December. This is a fascinating variable star that has more than one period of oscillation. The two (or more) periods sort of beat together causing the variation in amplitude. The main period is just under two hours. This is one I would like to do again and if possible for a longer time.
