Vend95: independent discovery of a flare star in front of M31
I've just found a rather bright transient on M31 images taken by Tamás Tordai tonight (28 September, 18:38 UT) . It appears to be an optical flare of a known foreground star . The recent flare has been detected by Flavio Castelli et al. as AT 2026adgl just 21 minutes earlier than our image was taken. Our images taken at 19:22 UT clearly show that the object had faded significantly during the 44 minutes since the previous set of images was obtained. Further investigation showed that the star was brightest on the 2×120 s images taken by Tamás Tordai at 18:33 UT, and then faded steadily on the images obtained later.
