SUPERNOVA 1992ah IN ANONYMOUS GALAXY
J. Mueller reports her discovery of a supernova of red mag about 17
on a plate taken June 27 UT by C. Brewer and J. D.Mendenhall with
the 1.2-m Oschin Telescope in the course of the second Palomar Sky
Survey. SN 1992ah is located 25" west and 8" south of the centre
of an anonymous galaxy located at R.A. = 17h35m26s.23,
Decl. = +12 56'00".3 (equinox 1950.0).

NOVA SAGITTARII 1992 No. 2
William Liller, Vina del Mar, Chile, reports his discovery with
Problicom on technical pan film (+ orange filter) of a nova at
R.A. = 18h20m18s, Decl. = -28 23'.7 (equinox 1950.0). Approximate
magnitude estimates: July 6.03 UT, [12.0; 9.157, 8.5. E. Waagen,
AAVSO, forwards the following visual magnitude estimates:
July 10.19 UT, 7.8 (P. Sventek, Houston, TX); 10.20, 8.0 (M. Adams,
Melbourne, FL); 10.23, 8.2 (C. Scovil, Stamford, CT).

Editor:
There appears to be some confusion over the declination of this
object which is given as -20 23.7' by some alternative sources.
We are awaiting clarification and a chart.
PERIODIC COMET GICLAS (1992l)
S. Nakano, Sumoto, Japan, reports the recovery of this comet by
T. Seki, Geisei, in very close agreement with the prediction on
MPC 14594 (ephemeris on MPC 19706). The comet is very diffuse with
central condensation. On July 9, m2 = 19.0.
