Nova Cas started to fade?
- subject: Nova Cas started to fade?
Following latest report suggests that Nova Cas 1993 may be entering
the expected "great minimum". Observations for these few nights would
be critically important.

Time system is Universal Time. Magnitudes are calculated from the frac-
tional method or Pogson's step method. CL = class: estimated accuracy of
observation; 1 = good (+/- 0.1 mag.), 2 = fair (+/- 0.2 mag.). CD = code:
I = in-focus observation, O = out-of-focus observation. Instrument (type,
aperture in mm and magnification): C = catadioptric telescope; L = refrac-
tor; M = Newtonian reflector. This report contains new observations (*)
since Report No. 12 (1994 February 4).
Comparison stars (idenfifications and V-magnitudes): Dm = 7.61; Em = 8.0,
8 = 8.28; Eg = 8.30; 9 = 8.56; Fg = 8.64; 10 = 9.35, 11 = 9.80, 12 = 10.37.
Identifications: The Astronomer (4, 8, 9, 10, 11, 12) and NAS.VSS (Dm, Em,
Eg, Fg). Magnitudes are from TA E-Circular 806 (8, 9, 10, 11, 12), Hippar-
cos Input Catalogue (Eg, Fg) and Sky Catalogue 2000.0 (Dm, Em). Magnitudes
for the numbered stars are due to Brian Skiff, Lowell Observatory.
Observers: Bjoern H. Granslo (Fjellhamar, Norway); Andreas Lauvstad
(Levanger, Norway); Oernulf Midtskogen (Tranby, Norway; Competa, Spain).
