NOVA ANDROMEDAE 1988
R.E.Royer reports the following approximate photovisual magnitude
estimates obtained with the 0.46-m telescope at Ford Observatory
California: 1988 June 21.46, 17; July 13.46, 17.5-18.0.
IAUC 4628
Further astrometry by B.Manning and D.Buczynski indicate that the
nova is not the same object as the magnitude 18 image on Palomar.
Further research is being carried out but it appears the two
objects may be separated by about 2-3". It is thus not clear from
the above report by Royer whether the results relate to the nova or
the Palomar mag 18 star. We are endeavouring to clarify this.
AS 296
R.H.McNaught, Siding Spring Observatory, reports that this star
appears in outburst on Atlas Stellarum, 1968 July 27, at magnitude
B=12.9. Examination of Schmidt survey films from 1984-86 gives
evidence of only slight variability around minimum. Patrol photos
by McNaught in 1986-87 yield a minimum magnitude of V about 11.8.
Estimates from recent patrol photos:
1988 May 21.59UT, 11.5; June 12.67, 10.4; 13.70, 10.4; 23.76, 10.0;
24.72, 10.0; July 11.59, 10.0. IAUC 4628
NSV 03005
D.H.Kaiser et al report on this star in IBVS 3196. The star is:
BD +17 1281, HD 258878, SAO 095781,
a magnitude 8 star at:
RA 06h28m47.7s DEC +17 07'08.2" (1950).
Although the NSV casts doubt as to its variability, Kaiser has
discovered variability during a photographic nova patrol using
PROBLICOM. On 1988 March 21, he detected a marked decrease in
brightness. It is a probable long-period eclipsing binary with
approximate visual range 8.0-10.0. A chart and photoelectric
sequence will shortly be available via the TA chart service.
