SUPERNOVA 1985L IN NGC 5033
A. V. Filippenko, University of California at Berkeley; and
W. L. W. Sargent, California Institute of Technology, report that
spectra obtained on June 26 and 27 with the Palomar 5-m telescope
over the range 420-690 nm show supernova 1985L to be a type II
object, probably near or just beyond maximum brightness.
G. Kriss, observing with the McGraw-Hill 1.3-m telescope,
reports that a low-dispersion spectrum of supernova 1985L shows
broad lines of H, indicating that the object is a type II supernova
at least two weeks past maximum; mv = 13.2 +/- 0.2 on June 29.
C. Gry and W. Wamsteker, IUE Observatory, Madrid; and N.
Panagia and D. Macchetto, Space Telescope Science Institute,
Baltimore, telex: "We observed supernova 1985L on June 28 with IUE.
The fine-error-sensor magnitude was 13.3. The mean flux was 0.7
and 2.1 x 10**-16 J m**-2 s**-1 nm**-1 in the short-wavelength (123-195
nm) and long-wavelength (195-320 nm) ranges, respectively. The
spectrum resembles that of a type II supernova after maximum."
C.-Y. Shao, Center for Astrophysics, reports the following
photographic magnitude estimates from the Damon sky-patrol plates
taken at Oak Ridge Observatory: June 11.12 UT (prediscovery),
12.3; 19.17, ~ 13.0; 22.09, 12.5.
COMET MACHHOLZ (1985e)
The following infrared magnitudes (27" diaphragm) were
obtained on June 24.75 UT by J. Stoddart and E. Ney at the O'Brien
Observatory: [2.2 microns], 4.4; [3.6 microns], 1.5; [4.8 microns], -0.1;
[8.5 microns], -1.3; [10.6 microns], -1.9; [12.5 microns], -2.0.
NSV 7429 AND LILLER'S VARIABLE
R. H. McNaught, Siding Spring Observatory, telexes that his
remarks on IAUC 4075 about NSV 7429 refer to an object clearly
distinct from the possible nova reported by Liller. Liller's
object is much brighter than the object at R.A. = 16h02m56s02, Decl. =
-51deg54'58"9 (not 57"9; equinox 1950.0), estimated at J ~ 17 on
1979 Mar. 22 and B ~ 20 on 1974 June 22 and presumed to be NSV
7429. McNaught's magnitude estimates on IAUC 4075 do refer to
Liller's object (therefore not a nova), measured by McNaught at R.A.
= 16h03m02s92, Decl. = -51deg56'32"6 (equinox 1950.0).
