PROBABLE SUPERNOVA IN INTERACTING GALAXY
     E. P. Aksenov, Sternberg Astronomical Institute, reports that
I. D. Karachentsev and I. M. Kopylov, Special Astrophysical Observatory,
have discovered a probable supernova 27" due east of the nucleus
of the interacting galaxy VV 5-42-11 = Zw 171-20 (R.A. = 17h52m.2,
Decl. = +30o43', equinox 1950.0).  On Apr. 30.0 UT mpg was 19.0.


NOVA IN LARGE MAGELLANIC CLOUD
     B. M. Lewis, Carter Observatory, communicates the following
photometric measurements (subsequently amended), made by W. S. G.
Walker, Auckland Observatory, of the second recent LMC nova (cf.
IAUC 3049): Mar. 24.431 UT, V = 12.65, B-V = -0.05, U-B = -0.75;
28.349, 13.07, -0.07, -0.73; Apr. 3.378, 13.46, +0.07, -0.68.


AM HERCULIS
     J. Mattei, American Association of Variable Star Observers,
communicates the following visual magnitude estimates: Apr. 17.3 UT,
12.9 (C. Ford, Wilton, Connecticut); 29.3, 12.6 (Ford); May 4.21,
12.7 (J. Morgan, Prescott, Arizona).  The chart and magnitude
sequence by S. Tapia were used (Liller 1977, Sky Telescope 53, 351).


R CrB VARIABLES
     R CrB.  Selected visual magnitude estimates: Mar. 20.19 UT,
11.3 (P. L. Collins, Harvard, Mass.); 26.05, 11.6 (M. Cavagna,
Milan, Italy); Apr. 4.52, 11.8 (Morgan); 13.10, 12.2 (J. Bortle,
Brooks Observatory); 24.45, 12.0 (Morgan); May 2.48, 12.9 (Morgan).

     SU Tau.  Visual estimates: Jan. 16 UT, 15.1 (P. Moore, Selsey,
Sussey); Feb. 19, 12.1 (Moore); Mar. 23.54, 11.3 (C. E. Spratt,
Victoria, B.C.); 28.46, 10.5 (Spratt); Apr. 6.54, 9.8 (Spratt).

     S Aps.  B. M. Lewis reports a photographic B magnitude of
14.0 on Mar. 24 and a visual estimate of 12.3 on Mar. 31.


NO METEORS FROM PERIODIC COMET GRIGG-SKJELLERUP
     H. Povenmire writes that the Florida Fireball Network observed
the expected radiant (IAUC 3055) between Apr. 23d00h and 23d03h UT
with moderately good conditions.  No associated meteors were seen.


1977 May 6                     (3069)              Brian G. Marsden
