0110 Nova Cassiopeiae 1995 - Photometry Update No. 11 (1996/01/24)
0120 =============================================================
0130
0140 Type: NB? Magnitude: 7.1 [V] - 18 [R] Spectrum: Pec(N)
0150
0160 This nova was discovered by Minoru Yamamoto (Okazaki, Aichi, Japan)
0170 on exposures from Aug. 24, 1995 [IAUC 6213]. Robert Argyle, Royal
0180 Greenwich Observatory, England, has reported the following accurate
0190 position (equinox J2000.0, FK5 reference frame, epoch 1995.69):
0200
0210 R.A. = 01h 05m 05s.353 Decl. = +54d 00' 40".12 [IAUC 6233]
0220 +/- 0s.004 +/- 0".07
0230
0240 It is based on 10 observations with the Carlsberg Automatic Meridian
0250 Circle on La Palma by C. Fabricius and M. Vallejo. The corresponding
0260 position for equinox B1950.0 is RA = 01h 02m 07s, Decl. = +53d 44'.6.
0690
0700 This nova underwent a major brightening in mid-December 1995, and
0710 at maximum it reached a visual magnitude near mv = 7.0. Thereafter it
0720 has faded quite rapidly to mv = 8.5, which was followed by a slower
0730 fade to its current magnitude around mv = 9.5, i.e. slightly fainter
0740 than at discovery. The light curve of Nova Cas 1995 has shown strong
0750 similarities to the bright nova in Delphinus in 1967 (HR Del).

0800 This report contains photometric observations of Nova Cas 1995. New
0810 entries since Report No. 10 (1996 Jan 11) are labelled by an asterisk
0820 (*), while revised data are identified by a cross (#). A dollar sign
0830 ($) identifies the discovery observation.

0860 revised observations since Report No. 10, is sent to the VARSTARS,
0870 VSNET and NOVA distribution lists, and the Usenet news groups
