Circular No. 3897 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 1365 P. O. Lindblad, Stockholm Observatory, and P. Grosbol, European Southern Observatory, report the following position and magnitudes obtained using a CCD on the 2.2-m telescope at La Silla on Nov. 27.17 UT: R.A. = 3h31m37s08, Decl. = -36deg18'56"2 (equinox 1950.0): V = 13.8, B-V = +0.9. This was apparently an independent discovery. V0332+53 R. W. Argyle, Royal Greenwich Observatory, telexes the following accurate position of a star of mpg = 16.5 measured on a plate taken on Nov. 23.757 UT: R.A. = 3h31m14s85, Decl. = +53deg00'24"5 (equinox 1950.0). This is the only star on the blue and red Palomar Sky Survey plates to fall within the +/- 15" error box of the EXOSAT position given on IAUC 3893. K. Kodaira, Tokyo Astronomical Observatory, telexes that his observations with the 1.9-m reflector at Okayama show the star at V = 15-16 with an emission-line nova-like spectrum on an interstellar-absorbed blue continuum (370-670 nm). P. L. Bernacca, T. Iijima and R. Stagni, Asiago Astrophysical Observatory, telex that faint H-alpha emission is present on two Asiago spectrograms obtained on Nov. 29 and 30. Rough photometry gives V = 14.6, B-V = +2.4; since no absorption bands characteristic of M- type stars are observed, the object is heavily reddened. Any modulation in V had an upper limit of 0.4 mag over timescales from 1 second to several minutes around Dec. 2.03 (simultaneously with EXOSAT observations) and 2.98 UT.
