SUPERNOVA 1992av IN ANONYMOUS GALAXY
C. Pollas, Observatoire de la Cote d'Azur, reports his discovery,
on OCA Schmidt technical pan films taken Aug. 21.96 and 22.97UT
(limiting mag 21), of an apparent supernova (V about 20) located
at R.A. = 17h43m14s.55, Decl. = +67 50'20".6 (equinox 1950.0).  SN
1992av is 10".9 east and 4".6 north of the center of a galaxy of
mpg about 18, and it is near the east tip of the galaxy's thin
disk, the disk being only visible on deeper films (limiting mag 22)
obtained one year ago.  Nothing is visible at this location on the
POSS prints.  A nearby star (V = 16.5) has end figures 16s.19,
51'13".7.  M. Turatto and S. Benetti report that SN 1992av was at
magnitudes B = 18.9, V = 18.6, and R = 18.7 when observed on Aug.
24.0 with the Asiago Observatory 1.8-m telescope (+ CCD).

COMET HELIN-LAWRENCE (1992q)
Eleanor F. Helin and Kenneth J. Lawrence have discovered a comet on
films taken with the 0.46-m Schmidt telescope at Palomar.
J. Alu and P. Rose assisted, and the latter measured the positions
below.  The object is slightly diffuse, with a strong condensation
but no perceptible tail:

TA AGM 1992
The meeting in Northampton yesterday was attended by approximately
60 observers and I would like to express my appreciation to Denis
Buczynski and Bob Marriott for looking after all the arrangements
this year.
