Birkle, Max Planck Institute for Astronomy, Heidelberg; H.Bohnhardt, Astronomical Institute, University of Munich; and G.Schwehm, ESTEC, Noordwijk, report their recovery of this comet with the prime-focus CCD camera on the 3.5-m reflector at Calar Alto, as follows: 1994 UT R.A. (2000) Decl. m1 Dec. 28.03183 10 29 24.2 +23 50 51 22 29.07865 10 29 22.7 +23 57 07 There was no detectable coma. The indicated correction to the prediction on MPC 20123 is Delta T = +0.15 day. IAUC 6122 SUPERNOVA 1994ak IN NGC 2782 S. Nakano, Sumoto, Japan, reports the discovery of a possible supernova (mag 16.3) by Reiki Kushida at Yatsugatake South Base Observatory. Found on an unfiltered CCD image taken on Dec. 24.856 UT, the candidate's position is R.A. = 9h10m50s.13, Decl. = +40o18'47".1 (equinox 1950.0; measured by Y. Kushida), which is 50" west and 30" south of the center of NGC 2782. Additional CCD magnitudes: Dec. 17, [16.4; 27.762, 16.1. A star of mag 16.7 is located 60" west and 35" north of the galaxy's center. IAUC 6122 M. W. Richmond, Princeton University; and R. R. Treffers,S. D. Van Dyk, and A. V. Filippenko, University of California at Berkeley, confirm that there is a new starlike object in NGC 2782, presumably a supernova. Observations were conducted as part of the Leuschner Observatory Supernova Search, which uses an automated 0.76-m telescope equipped with the Lawrence Berkeley Laboratory CCD camera. The supernova (R= 17.4 +/- 0.8) is located about 58" west and 33" south of the galaxy's nucleus in an image obtained on 1994 Dec. 30 UT; it is also barely visible in a mediocre image obtained on Dec. 23, but not visible (upper limit R = 19) in a good image on Dec. 1. S. Nakano, Sumoto, Japan, forwards the following additional unfiltered CCD magnitudes of SN 1994ak obtained with a 0.25-m Schmidt-Cassegrain by Y. Kushida at Yatsugatake South Base Observatory: 1994 Dec. 25.780 UT, 15.9; 28.591, 16.0; 29.619, 16.0; 31.616, 16.1; 1995 Jan. 1.645, 16.3; 2.600, 16.3. D. Balam, Climenhaga Observatory, Victoria, provides the following magnitude and precise 2000.0 position for SN 1994ak obtained on Jan. 3.44 UT: V = 18, R.A. = 9h14m01s.47, Decl. = +40o06'21".5; the supernova is indicated as being about 43" west and 27" south of the galaxy's centre. IAUC 6123 BAA VSS DIRECTOR At a meeting of the BAA Council yesterday, Gary Poyner, Birmingham, UK was appointed the new Director of its Variable Star Section. Gary will already be known to you as co-ordinator of the Recurrent Objects Programme of the UK Nova/Supernova Patrol. We extend our congratulations and best wishes to him in this additional new role for the British Astronomical Association. Guy M Hurst
