“New Star” in Vulpecula

On August 8th variable-star observer Hiroshi Abe discovered a bright nova in Vulpecula at right ascension 19h 54m 24.64s, declination +20° 52' 51.9" (equinox 2000). Its brightness was then magnitude 9.4. A possible progenitor star is visible on the Palomar Observatory Sky Survey-I plates at a visual magnitude of about 18.

This sounds like an ideal target for northern observers. You can plot the field using the American Association of Variable Star Observers' VSP utility. (Enter the coordinates given above.)

The nova is about 7 arcminutes from SS Vulpeculae, a red Mira-type variable.
