SN2002eh in NGC 917, discovered 2002 August 2. IAU Circular 7947 : Independent reports have been received of the discoveries of an apparent supernova on unfiltered KAIT CCD images obtained by LOTOSS, via B. Swift and W. D. Li, University of California at Berkeley, on Aug. 1.5 and Aug. 3.4 UT (mag. about 16.4) and by T. Boles, Coddenham, England, in the course of the UK Nova/Supernova Patrol on Aug. 2.10 (mag. 16.5) and 3.00 UT with a 0.35-m reflector. SN2002eh is located at RA 2h 26m 08s.45, Dec +31º 54' 45".2 (equinox 2000.0), which is 9".3 east and 1".0 north of the nucleus of NGC 917 (measurements by Li). A KAIT image taken on Feb. 1.2 UT showed nothing at this position (limiting mag. about 19.0). Boles adds that SN2002eh is not present on earlier images taken by himself or on second Palomar Sky Survey blue and red images.
