SUPERNOVA 1995am IN ANONYMOUS GALAXY
     M. Lovas, Konkoly Observatory, Budapest, reports his discovery,
on two 103a-D plates taken at Piszkesteto on Oct. 22.832 UT, of a
supernova (mag about 15.0) located 112" [sic] west and 10".0 south
of the center of a galaxy located at R.A. = 0h47m50s.14, Decl. =
+29o57'34".8 (equinox 2000.0).
     P. Garnavich, P. Challis, and R. Kirshner, Center for
Astrophysics, write:  "A CCD image obtained by A. Goodman on Nov.
17.2 UT with the Mt. Hopkins 1.2-m telescope shows SN 1995am (V
approximately 17.5) as being 9" west and 8" south of the galaxy
center (and suggesting that Lovas' offset must be in error).  A
spectrum taken by E. Barton, also on Nov. 17, with the 1.5-m
Tillinghast telescope indicates that this is a type-Ia supernova
observed 4-6 weeks past maximum.  The spectrum of the host galaxy
shows narrow emission lines of H-alpha, [N II], and [S II] at a
redshift of 0.017."


SUPERNOVA 1995an IN UGC 3188
     J. Mueller reports her discovery of a supernova (blue mag
about 17.5) on a plate taken with the 1.2-m Oschin Schmidt
telescope on Oct. 27 UT by D. Griffith and herself in the course of
the second Palomar Sky Survey.  SN 1995an is located 11" west and
3" north of the center of UGC 3188 (R.A. = 4h51m.8, Decl. = +8o50',
equinox 2000.0), clearly on a spiral arm.
      L. Wang and J. C. Wheeler, University of Texas at Austin,
communicate:  "A spectrum with low signal-to-noise ratio was
obtained on Nov. 17 UT with the 2.1-m telescope at McDonald
Observatory; SN 1995an shows prominent H-alpha emission (FWHM about
8450 km/s) with a weak P-Cyg profile, indicating a type-II
supernova.  The redshift of the host galaxy is about 3430 km/s
as measured from neighboring H II regions."


COMET 29P/SCHWASSMANN-WACHMANN 1
     L. Jorda and J. Lecacheux, Observatoire de Paris, Meudon; and
F. Colas, Bureau des Longitudes, report: "We have imaged this comet
on Nov. 14.21 UT with the 1.05-m telescope (+ broadband Schott KG1
filter) at Pic du Midi Observatory.  The comet shows a dust shell
spanning p.a. 105-290 deg, and a prominent jet of length 24"
(110 000 km at the comet) in p.a. 10 deg.  We estimate m1 = 13.7
+/- 0.5, from integration within a 1'-diameter field-of-view (and
comparison with 3 nearby GSC stars).  The image is available at
http://www.bdl.fr/imagespic.html."
