Patrick Schmeer, Germany comments on possible progenitors: Astrometry by H. Abe (IAUC 7686) gave: R.A. 21h03m02.00s Decl. +48o45'52.9" (J2000.0) Within 1" of this position is the following USNO-A2.0 star: R.A. 21h03m02.017s Decl. +48o45'53.55" (2000.0) r= 18.8 b= 19.6 On the DSS image there is another mag 19 star 5" to the NNW and a mag 20-21 star 4" to the NE of the USNO star. If the USNO star is the progenitor then the nova would be currently 12 magnitudes brighter than at quiescence. Giovanni Sostero, Italy, e-mails us to report his photometry with the 0.3-m Baker camera and CCD using B, V Johnson and R,I Cousin. The accuracy is +/- 0.03 magnitudes in each filter. 2001 August 19.84UT, V=6.66 B-V =+1.1 V-R =+0.5 R-I =+0.9 Guy M Hurst
