SUPERNOVA IN NGC 4185
     B. Szeidl, Konkoly Observatory, cables that M. Lovas has
discovered a supernova 28" east and 47" south of the nucleus of NGC
4185 (R.A. = 12h10m.8, Decl. = +28o47', equinox 1950.0).  On Mar. 22 the
photographic magnitude was 17.5.


SUPERNOVAE IN ANONYMOUS GALAXIES
     R. Wood, Royal Greenwich Observatory, writes that 60-min
exposures with the 0.66-m refractor by R. W. Argyle on Mar. 1 of the
fields of the new supernovae reported on IAUC 3671 showed no trace
of either object.  Transparency was excellent, and the limiting
photographic magnitude expected to be 17.5-18.0.


TT ARIETIS
     J. Mattei, American Association of Variable Star Observers,
informs us that this novalike variable (R.A. = 2h04m.2, Decl. = +15o03',
equinox 1950.0), normally around mag 11.5-11.8, is evidently fading.
Visual magnitude estimates by J. Bortle, Stormville, NY, are: Mar.
4.03 UT, 11.8; 13.04, 12.5; 15.02, 12.6; 24.03, 13.5.  The object's
last decline was in 1980 Nov. (cf. IAUC 3541).


RY SAGITTARII
     Mattei also reports that M. Overbeek, Edenvale, South Africa,
observed this R CrB-type variable (cf. IAUC 3662) at mv = 12.6 on
Feb. 28.13 UT.


1982 DV
     Further UBV photometry: Mar. 19.110 UT, V = 12.8, B-V = +0.8,
U-B = +0.75 (P. Gammelgaard and P. Bouchet, European Southern
Observatory); 21.110, V = 13.5, B-V = +0.85 (idem.); 25.444, V =
12.93, B-V = +0.79, U-B = +0.22 (R. Binzel, McDonald Observatory).


COMET BOWELL (1980b)
     Total visual magnitude estimates and coma diameters by J.
Bortle, Stormville, NY (0.32-m reflector): Feb. 26.47 UT, 11.7,
0'.5, 'only a smudge'; Mar. 4.41, 11.6, 0'.6.


1982 March 29                  (3683)              Brian G. Marsden
