October 19, 2011: Ovcharov et al. announced the detection of a bright transient in the region of M31 in ATEL #3691 (2011 October 19). They detected an object at R=10.95 on 2011 October 19.818. We are aware of no other confirming observations.
The object is at the following (J2000) coordinates:
RA: 00 44 55.27 Dec: +41 30 58.5
We note that this object is coincident with the blue source LGGS J004455.24+413059.7. Both visual and instrumental follow-up observations are strongly encouraged.
September 22, 2011: As detailed in AAVSO Alert Notice 448, Dr. Paula Szkody has requested monitoring of the WZ Sge-type cataclysmic variable V455 And through October 10. Observations tonight - September 22/23, tomorrow, and Saturday are crucial.
