Circular No. 3769 Central Bureau for Astronomical Telegrams INTERNATIONAL ASTRONOMICAL UNION Postal Address: Central Bureau for Astronomical Telegrams Smithsonian Astrophysical Observatory, Cambridge, MA 02138, U.S.A. TWX 710-320-6842 ASTROGRAM CAM Telephone 617-864-5758 SUPERNOVA IN NGC 1265 K. Birkle, T. Neckel and M. Sarcander, Max-Planck-Institut fur Astronomie, Heidelberg, and Centro Astronomico Hispano-Aleman, Calar Alto, report their discovery of a supernova 2" east of the center of NGC 1265 (R.A. = 3h14m9, Decl. = +41deg41', equinox 1950.0) on Jan. 29 with the 2.2-m telescope at a wavelength of 1 micron. The visual magnitude was estimated as 13 on Jan. 30.85 UT. SUPERNOVA IN ESO 323-G25 L. E. Gonzalez and J. Maza, Department of Astronomy, University of Chile, have confirmed the supernova in ESO 323-G25 (IAUC 3764). On Jan. 25.2 UT the photographic magnitude was ~ 18.5. V1343 AQUILAE M. Verdenet, Bourbon-Lancy, France, confirms with his visual magnitude estimates the very low minimum reported on IAUC 3750: 1982 Sept. 18.83 UT, 14.9; 20.83, 15.5; 22.82, 15.6; 25.83, 15.3. VARIABLE STAR IN ORION H. Kosai, Tokyo Astronomical Observatory, communicates the following additional observations (cf. IAUC 3763) by M. Huruhata on Jan. 21.61 UT: V = 14.3, B = 14.2. TWX 710-320-6842 ASTROGRAM CAM Contributors are advised that the preferred method for communicating urgent information to the Central Bureau is by telex to the above number. Since its inception in 1978 this system has been extremely reliable, and service is available 24 hours a day. If a 'public message' telegram or cablegram is being sent, the address should consist of the above number and answerback (and CAMBRIDGE MASS USA for a cablegram), supplemented by the words 'CENTRAL BUREAU FOR ASTRON CAMBRIDGE MASS' if desired. Messages should not be sent to the Smithsonian Astrophysical Observatory's answerback SATELLITE CAM. Telephone communication is generally not recommended, as staff is frequently unavailable to respond. Less urgent information (including all enquiries relating to subscriptions to these Circulars) should be sent by mail. 1983 January 31 (3769) Brian G. Marsden
