SUPERNOVA 1993ac IN ANONYMOUS GALAXY
Jean Mueller reports her discovery of a supernova (mag about 18) on
a IIIa-J plate taken by herself on Oct. 13 UT with the 1.2-m
Oschin Schmidt Telescope in the course of the second Palomar Sky
Survey.  The new object is located 4" west and 31".6 north of the
nucleus of a galaxy at (R.A. = 5h41m.5, Decl. = +63o20', 1950.0).

PERIODIC COMET URATA-NIIJIMA (1993q)
This comet has been recovered by J. V. Scotti with the Spacewatch
telescope at Kitt Peak, as shown below.  A 11" coma was visible on
Oct. 20.49 (15" on Oct. 21.50); a 0'.4 tail was visible on both
nights in p.a. 290-292 deg; m2 = 22.7 on both nights.  The
indicated correction to the prediction on MPC 16380 is
Delta(T) = +0.24 day.

Further estimates (cf E782):
1993 Oct 12.826, 14.6 (Tony Vanmunster, Belgium)
         15.780, 14.7 (Gary Poyner, Birmingham)
         21.772, 14.9 (Poyner)

V344 LYRAE
Gary Poyner relays that Tony Vanmunster has observed a maximum of
V344 Lyrae: 1993 Oct 18.812UT, 15.0. Gary Poyner confirmed this
sighting:
1993 Oct 18.815, 15.1; 18.913, 14.7.

TAV 1831+19
Gary Poyner also reports his confirmation that the northern
component of a pair is the variable as the following results show:
                    Northern Component     Southern Component
1993 Aug 16.888UT        12.5                    13.1
     Oct 17.791UT        11.2                    13.1
He further notes that the variable has a strong red colour.

SAO 96985
Tim Haymes, Reading, writes that he observed a lunar occultation
of this star (=BD +17 1596 = ZC 1141) on 1993 Oct 9. The star was
seen 06.50-07.00UT as a magnitude 5.6 primary but a companion of
about magnitude 6 was also noted at PA 045 approximately 5-10
arcseconds distant from 'A'. The position of the primary is:
RA 07h28m55s Dec +17 11 [1950].
This observation was in daylight but subsequently he again observed
the star in darkness on Oct 15 (02.30-03.30UT) but did not see the
companion. The Editor notes that the star is not listed as double
in catalogues so far checked, in particular the CD Rom edition of
the Washington Catalog of Visible Doubles (1984). Can anyone shed
further light on this result?
