New Variable in M31

K. Hornoch reported a new variable star in M31. On the DSS-II red plates, the star is not present at limiting magnitude of R=20.5. The object was first detected on 2001 August 16 at R=17.9mag, and then confirmed in 2002 August. V-R index of this variable is larger than of surrounding stars with comparable brightness, roughly estimated of about 1-1.5 mag. Probably large amplitude and large V-R index suggest, that it may be a Mira-type variable. Following to his report, T. Kato suspected that the object might be a nova in M31 (vsnet-campaign-nova 964).
