	Concerning SS Cyg: SS Cyg varies erratically. It never gets naked eye visible-I have a couple of images with my Kodak when it got to its brightest. So I doubt that it will be in the pictures you mention. If SkyNet had northern hemisphere coverage it would be fun to watch SS Cyg. Vivian Hoette certainly has followed this variable extensively. It is a perfect project for using the Yerkes rooftop. But everything takes time and we already have our plates full.--[[User:Decoster\|Richard DeCoster]] 20:48, 30 July 2010 (PDT)		Concerning SS Cyg: SS Cyg varies erratically.

		+	Concerning the PAINT thing: Thanks for your response and please elaborate. It used to be that when I did copy/paste into paint I got a nice sized image. I still do at school. But about 4 months ago I opened a file I obtained elsewhere and my PAINT "default" got reset and I can't figure out how to go back to my useful settings.--[[User:Decoster\|Richard DeCoster]] 20:52, 30 July 2010 (PDT)

	The paint thing - I think we found that you had to crop to exactly what you wanted included in your image to get rid of all that white. Rebecca is that right?--Peggy Piper 13:55, 29 July 2010 (PDT)		The paint thing - I think we found that you had to crop to exactly what you wanted included in your image to get rid of all that white.

	So... SS Cyg varies over the course of weeks? I've got some images of Cygnus from the past two weeks up a yerkes and I think I have some from the grand canyone, that would be first two weeks in June. Should I actually see variation? --Peggy Piper 13:51, 29 July 2010 (PDT)		So... SS Cyg varies over the course of weeks?

 *Also, I started a page a bit ago of the Niles West sub-group's effort to observe longer period variables such as Mira-type and Cepheid-type, the latter that Joey alluded to.  The Mid-IR group, i.e. us, is looking for variables with even shorter periods, on the order of which we can observe with our several hours long data sets.  See "Mr. DeCoster's LPV Material" under one of our sub-headings.<BR>

 AAVSO recently greatly modified [?improved] its web page.  I am still trying to recoup.
 *We took some pictures at Yerkes last night of one of the more famous variable stars SS Cygni.  I'll try to post one such picture.
