TWX 710-320-6842 ASTROGRAM CAM Telephone 617-864-5758 SUPERNOVA IN ANONYMOUS GALAXY J. Maza, Department of Astronomy, University of Chile, reports the discovery by L. E. Gonzalez at Cerro El Roble of a possible supernova 1" east and 6" south of the nucleus of an anonymous spiral galaxy at R.A. = 5h48m0, Decl. = -24deg02' (equinox 1950.0). The object was recorded on Jan. 3 at mpg = 18.0. PERIODIC COMET CROMMELIN (1983n) Further precise positions will be published on the MPCs. Orbital computations by D. K. Yeomans, Jet Propulsion Laboratory, show that this comet has a very slight secular acceleration (A2 = -0.0004 from observations 1873-1984, A2 = -0.0008 from observations 1928-1984); for current ephemeris purposes the orbital elements on IAUC 3886 are quite adequate. Further visual magnitude estimates: Jan. 25.98 UT, 10.5 (J. Bortle, Stormville, NY, 0.32-m reflector); 29.15, 9.9 (C. S. Morris, Frazer Park, CA, 0.20-m reflector); 30.07, 9.8 (R. Keen, Boulder, CO, 0.32-m reflector). NEW INFRARED SOURCE E. R. Crane, Tucson, reports that his search of the near- infrared photographic sky survey (NIPSS) has revealed an extremely red star at R.A. = 4h52m04s, Decl. = +44deg27'6 (equinox 1950.0), that may be identical with the 2.2-micron infrared source reported by Ashok et al. (IAUC 3906). At an estimated V ~ 15.5, V-I ~ 6, it is by far the reddest star in the immediate vicinity. The object appears completely stellar, and examination of three sets of photographs shows no evidence for large-scale brightness variations. 2CG 195+04 = 'GEMINGA' With reference to IAUC 3907, we point out that C. Vanderriest told us that the position originally reported was possibly incorrect--but not until IAUC 3892 had been printed. He adds that the upper limit on parallax and proper motion is still valid.

Verdenet, Bourbon-Lancy, France: 1983 Sept. 24.8 UT, 15.0; 27.8, 14.4; 30.8, 14.6; Oct. 3.8, 14.2; 6.8, 15.2; 7.8, 15.6; 8.8, 15.2. 1984 February 1 (3913) Brian G. Marsden
