POSSIBLE NOVA IN M31: M31N 2010-08a
Rafael Ferrando, Segorbe, Spain, reports his discovery of an apparent
nova (mag about 18.5) in M31 from five 120-s unfiltered CCD frames (limiting
mag 20.0) taken around Aug. 8.16 UT with a 0.40-m f/10 Ritchey-Chretien
reflector, the new object located at R.A. = 0h43m28s.28, Decl. = +41d41'25".0
(equinox 2000.0 assumed, not stated). A possible faint object is visible at
this location on an image from 2009 Aug. 26.13, which is posted by Ferrando
at the following website URL: http://pladearguines.com/NOVAM31-20100808.gif.
