RS OPHIUCHI
     Total visual magnitude estimates: Jan. 29.41 UT, 5.6 (C.
Scovil, Stamford, CT); 29.46, 5.3 (W. Lowder, Tuckahoe, NY;
independent discovery of outburst); 30.22, 6 (G. E. D. Alcock,
Peterborough, England; independent discovery of outburst); 30.27, 5.9
(G. M. Hurst, Basingstoke, England); 30.42, 5.8 (K. Danskin,
Amherst, NH); 30.57, 6.1 (R. Ducoty, Capitola, CA); 30.77, 6.0:
(R. H. McNaught, Coonabarabran, N.S.W.).  The last outburst of
this recurrent nova occurred in 1967 (IAUC 2041, et seq.).


NOVA NORMAE 1985
     McNaught provides the following visual magnitude estimate of
Liller's presumed nova (IAUC 4030): Jan. 30.75 UT, 12.7.


SUPERNOVA 1985A IN NGC 2748
     P. Wild, Astronomical Institute, Berne, reports that T.
Schildknecht has discovered a supernova at R.A. =  9h08m00s38, Decl. =
+76deg40'45"1, 3" west and 10" south of the nucleus of NGC 2748.
The object was at mpg = 14.5 on Jan. 25.09 UT, and a confirmatory
observation was made on Jan. 31.0.


POSSIBLE FOREGROUND VARIABLE IN NGC 1023
     J. Sinclair, Royal Greenwich Observatory, confirms that the
supposed supernova (IAUC 4025, 4028) is a foreground star at R.A. =
2h37m11s5, Decl. = +38deg50'45" (equinox 1950.0), 49" west and 11" south
of the nucleus of NGC 1023.  Photometric data provided by I. M.
Kopylov, Special Astrophysical Observatory, suggest that the object
is indeed variable: 1984 Dec. 25.7 UT, V = 13.36 +/- 0.02, U-B
= +0.8 +/- 0.1, B-V = +0.96 +/- 0.03, V-R = +0.66 +/- 0.02; Dec. 28.8, V
= 13.69 +/- 0.03, B-V = +0.88 +/- 0.03, V-R = +0.66 +/- 0.03.  Wild
also suggests that the object is irregularly variable by ~ 1 mag.


PERIODIC COMET WOLF-HARRINGTON (1984g)
     Total visual magnitude estimates: 1984 Oct. 2.45 UT, 13.3
(C. S. Morris, near Mt. Wilson, CA, 0.25-m reflector); Nov. 27.50,
12: (R. Keen, Mt. Thorodin, CO, 0.32-m reflector); Dec. 2.50, 13.2
(Morris, Whitaker Peak, CA).
