SUPERNOVA 1989V IN ANONYMOUS GALAXY
     C. Pollas, CERGA, reports his discovery with the 0.9-m Schmidt
telescope on 1989 Dec. 28.80 UT of a possible supernova of mag about
18.5 at R.A. = 1h29m18s.84, Decl. = +11d56'29".1 (equinox 1950.0),
0".9 west and 2".1 south of the nucleus of a compact anonymous galaxy
of mag 18.  The object was confirmed on Dec. 31.74 UT.  There is a
nearby star of mag 16 at end figures 17s.26, 16".5.

COMET OKAZAKI-LEVY-RUDENKO (1989r)
     R. H. McNaught reports that a 60-min tracked J plate taken on 1989
Dec. 30.50 UT by A. Savage and C. A. Frost with the Anglo-Australian
Observatory's 1.2-m Schmidt telescope showed a 20' tail in p.a. 40 deg
and a narrow 6' antitail in p.a. 225 deg.
     Total visual magnitude estimates: 1989 Dec. 20.21 UT, 8.0 (K.
Abasolo, Laja, Chile, 0.32-m reflector); 25.60, 8.5 (A. Pearce,
Scarborough, Western Australia, 0.20-m reflector); 28.47, 9.1 (G.
Garradd, Tamworth, N.S.W., 10 x 50 binoculars).
