     A. R. Klemola, Lick Observatory, reports that a comet has been
discovered by Merlin Kohler, Quincy, California.  The comet was confirmed
by E. A. Harlan with the Lick 51-cm double astrograph.  The
following observations are available:

     1977 UT             R. A. (1950) Decl.        m1    Observer
     Sept. 4.208      15 24         +30           10     Kohler
           6.16667    15 26 26.54   +28 58 55.0   11     Harlan

M. Kohler (Quincy, California).  20-cm reflector.  Daily motion 0o.5
   southeast (or northeast).  Diffuse without nucleus; no tail.
E. A. Harlan (Lick Observatory).  40-min exposure.  Trail diffuse
   with slight condensation.  Daily motion derived from this exposure
   as Delta-RA = +2m.05, Delta-Decl. = -19'.  Measurer: Klemola.

     This comet has been independently recovered by Z. M. Pereyra
with the 154-cm reflector at Bosque Alegre as follows:

     1977 UT          R. A. (1950) Decl.        m2
     Aug. 19.27890    2 11.44    -10 37.4      19.2
          20.23576    2 12.35    -10 45.1
          21.32455    2 13.42    -10 54.6
          22.29806    2 14.40    -11 03.6

The object is stellar in appearance.

     T. G. Hawarden, U.K. Schmidt Telescope Unit, Siding Spring
Observatory, reports that an observation on July 14 by D. A. Jauncey
with the image-dissector scanner on the 390-cm Anglo-Australian
telescope shows that the spectrum of this supernova (cf. IAUC 3091)
closely resembled that of  1972E in NGC 5253 some 200-230 days after
maximum.  Broad H-alpha emission was present, and there were broad
emission features with P Cyg profiles centered at 4700, 5300, 5900
and possibly 7100 A.  The supernova, of type I, was evidently near
maximum at the epoch of the discovery plate.  The position is now
given as R.A. = 3h38m00s.45, Decl. =  -44o10'17" (equinox 1950.0).

1977 September 7               (3103)              Brian G. Marsden
