1980 AA
Antonin Mrkos, Klet Observatory, reports the discovery of a
fast-moving asteroidal object as follows:
1980 UT R. A. (1950) Decl. Mag.
Jan. 13.89501 6 54.7 +30 16 13.0
The daily motion is 155' in p.a. 120o.
POSSIBLE SUPERNOVA IN NGC 1199
P. Laques, J.-L. Nieto and J.-L. Vidal, Observatoire du Pic du
Midi, report the observation on a single electrographic plate of a
bright stellar object in NGC 1199. The plate was obtained on 1979
Sept. 28.1 UT, and the object, of estimated apparent magnitude 17,
is located 13" from the center in p.a. 230o. The object is not
visible on an electrographic plate obtained on Dec. 18.0 UT.
Information concerning other observations of this galaxy during the
past six months would be appreciated.
SUPERNOVA IN NGC 4321
K. M. Merrill, Kitt Peak National Observatory, reports the
detection of this object (cf. IAUC 3371, et seq.) in the infrared.
Observations on Jan. 3 with the 4-m telescope gave J = 14.8, H =
13.4, K = 12.2, L = 10.6, consistent with dust formation.
OCCULTATION OF AGK3 +0 1022 BY (3) JUNO
Further analysis indicates that the observation at Central
Michigan University (IAUC 3431) is spurious. R. Millis reports:
"Observations of the 1979 Dec. 11 occultation by (3) Juno were
obtained at eleven sites by astronomers from Lowell Observatory,
Massachusetts Institute of Technology, Jet Propulsion Laboratory, the
University of Maryland, California Institute of Technology and the
University of Southern California. Preliminary analysis gives axes
291 +/- 3 and 243 +/- 5 km for the best-fitting elliptical profile of
Juno. No secondary occultations were seen. A detailed analysis of
the observations is in progress. Other observers wishing to have
their observations included in this analysis should contact me at:
Lowell Observatory, P.O. Box 1269, Flagstaff, AZ 86001, U.S.A."
