PROBABLE NOVA IN SERPENS
     H. Kosai, Tokyo Astronomical Observatory, telexes that M.
Wakuda, Hamamatsu, Shizuoka, has discovered an object, presumably
a nova, at R.A. = 17h53m0, Decl. = -13deg58' (equinox 1950.0).  The
object was detected on Tri-X film with a green filter.  Magnitude
estimates: Feb. 21.8 UT, [11; 22.802, 7.7; 24.83, 8.2.


SUPERNOVA IN ANONYMOUS GALAXY
     J. Maza, Department of Astronomy, University of Chile, reports
his discovery of a supernova near an anonymous spiral galaxy
located at R.A. = 11h51m7, Decl. = -28deg47' (equinox 1950.0).  The
supernova, which is 16" east and 16" north of the galaxy's nucleus, is
evidently associated with a fainter, interacting, compact galaxy.
On the discovery plate, taken by L. E. Gonzalez and Maza with the
Maksutov astrograph at Cerro El Roble on Feb. 13, the supernova
was of mpg 19; a prediscovery plate on Jan. 12 shows it at mpg 18.


PERIODIC COMET BOWELL-SKIFF (1983c)
     Precise positions obtained by J. Gibson at Palomar:

          1983 UT               R.A.   (1950.0)   Decl.

          Feb. 20.34933       9 21 49.35      +18 22 17.3
               21.42225       9 21 25.20      +18 20 02.7


PERIODIC COMET SCHWASSMANN-WACHMANN 1
     Total visual magnitude estimates by J.-C. Merlin, Le Creusot,
France (0.26-m reflector): Feb. 19.05 UT, 12.0; 20.03, 11.9.

OMEGA ORIONIS

     D. P. Hayes, Astronomy Department, Columbia University,
writes: "The linear polarization of the Be star omega Ori recently
underwent a sharp change.  On Jan. 21 this star's polarization was
P = 0.14 percent, O = 71.4 degrees (i.e., primarily interstellar), but
by Feb. 9 it had changed to P = 0.49 percent, O = 43.6 degrees.
Observers, especially those using different techniques, are urged to
monitor the star.  Polarization observations will continue at Columbia
University's Harriman Observatory until about Apr. 15."


1983 February 25               (3777)              Brian G. Marsden
