AAVSO Alert Notice 529 announces a campaign from Dr. George Wallerstein (University of Washington) on 5 variables in Cygnus. Please see the Alert Notice for details and instructions.
Many thanks, and good observing!

I'd love to help on this one, but VX Cyg seems to have only one comp in the 30 arc-min field. Any chance of getting a sequence for this one?
Thanks!

Of course it depends on your equipment. VX (and in fact all the stars on this list) are easily observable visually using a small telescope, or a medium sized one using a long focal length eyepiece. For all but X Cyg (a binocular variable) I am using a 2 degree chart and a 24 mm eyepiece with my 180mm f/6 Mak-Newt. That yields plenty of comparison stars.
I don't mean to be lecturing; what is intended is to encourage others to participate!
The notice did say, "V and visual observations are requested". So it makes sense to have a sequence appropriate for CCD photometry as well.
