PROBABLE NOVA IN NORMA
     William Liller, Vina del Mar, Chile, reports his discovery of
a probable nova in the course of the PROBLICOM survey, and provides
following position (+/- 5"): R.A. = 15h36m48s8, Decl. = -51deg03'23"
(equinox 1950.0).  On Jan. 26.310 UT, mv = 10.5, and on Jan. 27.318, mv
= 10.7.  Nothing appears on his survey photographs (limiting mag ~
12.0) in this position back to 1981.


RS OPHIUCHI
     W. Morrison, Peterborough, ON, reports this recurrent nova to
be in outburst for the first time in over 25 years, providing the
following visual magnitudes: Jan. 26.47 UT, 6.8; 28.45, 5.2.


IR GEMINORUM
     S. Lubbock, St. Bridges Major, South Wales, communicates that
this dwarf nova is undergoing an unusual outburst only some 2 weeks
after its previous maximum.  His visual magnitude estimates: Jan.
22.803 UT, [13.8; 23.822, 13.8; 24.961, 12.3.


PERIODIC COMET TSUCHINSHAN 1 (1984p)
     Total visual magnitude estimates: 1984 Dec. 29.49 UT, 11.2:
(A. Hale, Whitaker Peak, CA, 0.20-m reflector); Dec. 31.45, 10.8
(C. Morris, Whitaker Peak, CA, 0.25-m reflector); 1985 Jan. 1.47,
10.7 (Hale); 3.52, 11.0 (Morris, near Mt. Wilson, CA); 18.50, 10.7
(Morris); 20.48, 10.7 (Morris).


PERIODIC COMET SCHAUMASSE (1984m)
     Total visual magnitude estimates: 1984 Dec. 2.53 UT, 9.6 (C.
Morris, 0.25-m reflector, Whitaker Peak, CA); 4.43, 9.6 (J. Bortle,
20x80 binoculars, Stormville, NY); 19.17, 9.5 (J.-C. Merlin, Le
Creusot, France, 0.07-m refractor); 24.42, 10.0 (Bortle, 0.32-m
reflector); 31.51, 9.8 (Morris); 1985 Jan. 18.52, 10.1 (Morris, near
Mt. Wilson, CA); 20.51, 10.1 (Morris).


CORRIGENDUM
     PKS 0537-441.  On IAUC 4027, line -6, for +0.56 read -0.56.
