A. Henden, AAVSO, notes that Palomar Sky Survey (POSS) plates show a close pair of objects at the location of the outbursting variable: one is essentially stationary, while the other has a relatively high proper motion. On the POSS-I plates, the southwest component of the 3"-separated double is obviously blue, while on the POSS-II plates, it has moved east-northeast by about 3" and is now about 1" southeast of the stationary northeast component. At this motion rate, it would be expected to lie an arcsec or two east of the stationary component at this epoch. This rate of motion would imply something intrinsically faint but relatively close; adding in the color would imply a white dwarf – suggesting that the moving object is the outbursting object and that it is a cataclysmic variable with an amplitude of about 6 magnitudes.
