PERIODIC COMET KOPFF (1988k)
E. M. Alvarez and M. J. S. Belton, National Optical Astronomy
Observatories; and K. J. Meech, Institute for Astronomy, University
of Hawaii, report their recovery of P/Kopff with the University of
Hawaii 2.2-m telescope on Mauna Kea. The object is centrally
condensed without any obvious coma; magnitude R ~ 21.

SUPERNOVA 1935C IN NGC 1511
S. van den Bergh, Dominion Astrophysical Observatory; and M. L.
Hazen, Center for Astrophysics, report that HV 11970, mentioned by E. H.
Boyce (1943, Harvard Bull. No. 917) as a possible nova associated with
the LMC and sometimes known as Nova Hydri 1935, is rather definitely a
supernova in NGC 1511 (R.A. = 3h59m.3, Decl. = -67D46', equinox 1950.0),
an alternative also suggested by Boyce. The object reached its observed
maximum of mpg = 12.5 on 1935 Sept. 19 and was located about 55" east
and 8" south of the galaxy's nucleus.
COMET MACHHOLZ (1988j)
L. Lebofsky, P. Owensby, and W. Golisch report broadband
infrared observations from the NASA Infrared Telescope Facility on
Mauna Kea on Aug. 23.7 UT. Through a 7".8-diameter aperture,
the monochromatic magnitudes were: J = 12.07 +/- 0.01, H = 11.57
+/- 0.01, K = 11.58 +/- 0.01, N = 2.61 +/- 0.02, Q = 0.90 +/- 0.20.
