Observations, Sept. 20, 2009
(JD 2455095)

This is a time series of observations of a dwarf nova cataclysmic variable in the constellation of Andromeda (V455 And). It last had a dwarf nova outburst (Magnitude 8) in 2007 and has been cooling since then. The observations were taken over a 4 hour period, consisting of two 110 min. series separated by a 3 min break. Viewing conditions were fair. The accompanying image shows the star field with the V455 And labeled as "V."
