HS 2331+3905

On 4th Sept 2007 AAVSO issued an alert regarding this object. The object is normally  Mag >16 but was reported as Mag 14.6 on 3 Sep and 9.15 on 5 Sep. Here is a SLOOH Dome 1 image on 6 Sept.

The image is from Dome 1 LM (HM field carries no useful comparison stars).  It is a combination of 2 images at (20:20 and 21:10 UT) resampled x2 and stacked then cropped to show the area of interest. The magnitude of some comparison stars is shown (Tycho 2 catalog Visual mag). I'm estimating 9.0 - 9.1.
