PERIODIC COMET GIACOBINI-ZINNER (1991m)
K. J. Meech, Institute for Astronomy, University of Hawaii; and
W. Weller, Cerro Tololo Interamerican Observatory, report the recovery
of this comet on CCD images obtained using the Hawaii 2.2-m telescope
(Feb. 16) and with the prototype wide-field CCD camera being
developed by Weller for use on the CTIO Schmidt telescope (Mar. 14
and 15). The February data were reduced by B. Mueller and K. Meech,
and the March data were reduced by K. Meech and T. Farnham. The
comet appeared stellar with a Mould r magnitude near 22. The indicated
correction to the prediction on MPC 14592 is Delta(T) = -0.01
day.

SUPERNOVA 1976P IN ANONYMOUS GALAXY
R. H. McNaught, University of Adelaide, reports his discovery
of a possible supernova of mag about 20 in an anonymous galaxy on
the SERC J survey. The J plate was taken by T. G. Hawarden on 1976
Apr. 2 with the U.K. Schmidt Telescope. The galaxy is small and
faint and contains two stellar objects, the fainter (mag about 18.5)
being more centrally placed and assumed to be the nucleus. The
other stellar image (mag about 17.5) is offset 3" due west, whereas
the supernova is 6" east and 0".7 north. Coordinates for the supernova
are R.A. = 8h07m33s.72, Decl. = -65 37'14".5 (equinox 1950.0).
Nothing appears in this position on the ESO B or R plates, nor on a
UKST R plate taken 1991 Feb. 18 by P. McKenzie. M. A. Read, Royal
Observatory Edinburgh, notes that, on a weak UKST J plate taken by
K. P. Tritton on 1976 Feb. 28, there is a slight density enhancement
at the position of the supernova suggesting a magnitude of about
21-21.5, if an image of the supernova. No image appears on another
UKST J plate taken 1975 Jan. 10.
