S. Benetti, ESO, writes: "Inspection of a fully-reduced spectrum (range 369.5- 757.8 nm, resolution about 0.6 nm), obtained on Jan. 14.15 with the ESO 1.52-m telescope (+ Boller & Chivens spectrograph) by the discoverer, confirms SN 1997D to be a peculiar type-II supernova, about 100 days after maximum. IAUC 6537 (extract) SUPERNOVA 1997E IN NGC 2258 S. Nakano, Sumoto, Japan, reports the discovery by Reiki Kushida, Yatsugatake South Base Observatory, of an apparent supernova (mag 15.7) on seven unfiltered CCD frames taken around Jan. 14.530 UT with a 0.40-m f/5 reflector. Y. Kushida provides the following measurement of the position of SN 1997E from the discovery frames: R.A. = 6h47m38s.10, Decl. = +74o29'51".0 (equinox 2000.0), which is 32" west and 57" north of the centre of NGC 2258. There is no star at the position of the new star on Kushida's frames taken on 1996 Dec. 15, 29, and 1997 Jan. 4, nor is anything present on the Digital Sky Survey. P. Garnavich and R. Kirshner, Harvard-Smithsonian Center for Astrophysics, communicate: "Spectrograms of SN 1997E were obtained by J. Peters on Jan. 16.2 UT at the F.L. Whipple Observatory (FLWO) 1.5-m Tillinghast telescope, showing this to be a type-Ia supernova at maximum.
