SN2000D in UGC 1767, discovered 2000 January 22/24. IAU Circular 7350 : G.M. Hurst, Basingstoke, England, reports the discovery by Tom Boles of an apparent supernova (mag 16.2) on unfiltered CCD images taken on Jan 22.928 and 24.806 UT in the course of the UK Nova/Supernova Patrol. SN2000D is located at RA 2h 18m 04s.84, Dec +38º 04' 27".4 (2000.0; mean of two measures), which is 6" west and 11" south of the center of UGC 1767. Confirming images of SN2000D were obtained by R. Arbour, South Wonston, on Jan 24 and by M. Armstrong, Rolvenden, on Jan 25.83. An image taken on 1999 Sept. 18.212 by Boles does not show the new object to a limit of mag. about 18. SN2000D is not present on the second Palomar Sky Survey (limiting mag. about 19), where Hurst notes that the new star is slightly northwest of an HII region.
