Telephone/FAX(0256)471074 Int:+44256471074 INTERNET: GUY@TAHQ.DEMON.CO.UK GMH at AST.STAR.RL.AC.UK ------------------------------------------------------------------- SUPERNOVA 1995E IN NGC 2441 (=Q1995/022) In response to our alert issued Feb 22 and designated Q1995/022 Dave Balam, Dominion Astrophysical Observatory, Victoria, Canada confirmed the new object and measured positions for us as follows: 1995 Feb 23.267UT SN RA 07h51m56.75s DEC +73 00'34.6"(2000) Galaxy 07 51 54.79 +73 00 55.2 He calculates the offsets as: 8.6"E, 20.6"S Based on 11 GSC stars he reduces the V magnitude as 15.9. Jost Jahn, Bodenteich, Germany also e-mails in response to our appeal. He reports that Emil JUng, Marl, Germany imaged the new star on 1995 Feb 22.898UT and measured its position with end figures: RA 56.73s DEC 35.5"(2000) in excellent agreement with the result above by Dave Balam. The image was secured with a Celestron 8 and ST-6 CCD. The IAUC announcement has now appeared as follows: P. Molaro, Trieste Observatory, reports the discovery by Alessandro Gabrielcic, Agordo, Italy, of an supernova in NGC 2441 (R.A. = 7h52m.2, Decl. = +73o02', equinox 2000.0), the new object being at mag V about 15 on the CCD discovery frame taken on Feb. 20.85 UT. SN 1995E is located 7" east and 22" south of the galaxy's centre. Molaro, C. Boehm, and G. Tessicini further report that their spectrogram (range 500-900 nm, resolution FWHM about 1.8 nm) taken with the 1.5-m Loiano Observatory telescope (+ BFOSC spectrograph) on Feb. 21.3 UT shows a strong absorption centered at 619 nm (FWHM 15.4 nm): "The presence of the absorption feature, which may be identified with Si II (635.5 nm), and the absence of pronounced H-alpha emission suggest that this is a type-Ia supernova. The expansion velocity amounts to -11000 km/s in the rest frame of NGC 2441, which is consistent with a type-Ia supernova close to maximum." SUPERNOVA 1995D IN NGC 2962 Nick James, Chelmsford, UK reports a precise position for this supernova obtained on 1995 Feb 17.83UT using the 0.30-m reflector plus Sony ICX027BL CCD. The reduction, using 8 GSC stars follows: RA 09h40m54.73s DEC +05 08'26.6"(2000) He estimates the magnitude as 13.1. The original precise position by Y.Kushida (IAUC 6134) produced a similar result with end figures RA 54.79s DEC 26.6"(2000) Recent visual estimates by Guy Hurst, Basingstoke, UK: 1995 Feb 21.921UT, 12.9; 22.945, 12.8.
