SY Andromedae in eclipse

  It looks like the eclipse prediction for SY Andromedae given in VSX for 6:07 UT September 28 is accurate, even though this EA is poorly observed. I got out and looked at it twice tonight. I haven't entered these visual estimates yet but will soon:

  1:35 UT September 28 = 12.1 mag.

  4:33 UT September 28 = 12.2 mag.

  Lots of cirrus clouds have moved in to stay here, but for anyone interested this star should spend the next 25 hours or so climbing back up to about 10.7 mag. It's not tough to find; just five degrees away from the Andromeda Galaxy M-31. The next eclipse won't happen until November 2. These long-period eclipsing binaries are fascinating to me for some reason!

  There isn't an official sequence yet but maybe I can request one. I've been using magnitudes from the Calsky website. They use USNO for the fainter stars, so I read.

SY And

Gents,

There is now an official sequence for SY And. I took an image Wed (10/1) with iTelescope T11 and used the new sequence.  I have 2 more images scheduled (Sat/Mon) and will add more as long as the weather holds in New Mexico.
