Just over a week ago the weather tried to play ball and give us some clear conditions but it wasn't that brilliant. The moon was at first quarter and there was light thin high-level cloud that made for poor variable transparency. I had been planning to have a good session of variable star observing with my 10x50 binoculars but in the end I only managed three stars:-
TX Dra, 18.45 UT, chart 106.04, K(5)V(2)N, mag. 7.5
AH Dra, 18.55 UT, chart 106.04, 2(3)V(2)6, mag 7.6
CH Cyg, 19.12 UT, chart 089.04, =H, mag 9.2
CH Cygni was very difficult and right at the limit of what I could observe in these conditions. I could only see it in averted vision. Because of the moon and the poor visibility I was worried that these estimates might not be very good, but on comparison with values from other BAA members it seems that they aren't too bad.
