Time system is Universal Time. Magnitudes were calculated from Pogson's
step method. CL = class: estimated accuracy of observation; 1 = good
(+/- 0.1 mag.), 2 = fair (+/- 0.2 mag.). Instrument (aperture in mm):
M = reflector, C = Schmidt-Cassegrain. New observations since Report No. 8
(1993 June 22) are marked with an asterisk (*).
Comparison stars: Ab = 6.93 (HIC); Bb = 7.56 (HIC); Ag = 7.8 (HIC); Bg = 7.86
(HIC); Cb = 8.27 (HIC); At = 8.60 (TA); Db = 8.89 (HIC); Ct = 9.44 (TA); Dt =
9.76 (TA); E = 10.25 (TA); G = 11.25 (TA); H = 11.8 (TA); J = 12.56 (TA); K =
13.24 (TA); L =13.41 (TA).
Sequences: HIC = The Hipparcos Input Catalogue; TA = The Astronomer Electronic
Circulars No. 745 and 756 (V-band photometry by S. Kiyota). Stars Ab, Bb, Cb
and Db are from a list supplied by H. Bengtsson.
The nova is located at RA = 19h 13m 06.7s, Decl. = +1d 34' 23" (2000.0).
Observers: Haakon Dahle (Oslo, Norway); Bjoern Haakon Granslo (Fjellhamar,
Norway); Oernulf Midtskogen (Tranby, Norway).
