This nova is now fading below the limits of Hipparcos/Tycho magnitudes and requires a standardised comparison sequence. The following stars have been selected to form this sequence. The positions are from USNO A1.0 and the V and B-V values are based on preliminary photometry from Arne Henden, USNO. Magnitudes are accurate to a few hundredths of a magnitude. The magnitudes to be used by visual observers are shown in the last column.
