SN2001ew – discovery

Tom Boles

SN2001ew in anonymous galaxy, discovered 2001 October 9. IAU Circular 7734 : G.M. Hurst, Basingstoke, England, reports the discovery of an apparent supernova (mag. 17) by T. Boles, Coddenham, England, on a 30-s unfiltered CCD frame (limiting mag. 18.5) taken with a 0.36-m telescope on Oct. 9.133 UT in the course of the UK Nova/Supernova Patrol. SN2001ew is located at RA 3h 13m 06s.98, Dec +42º 26' 15".1 (equinox 2000.0), which is 5" east of the nucleus of its host galaxy. M. Armstrong, Rolvenden, England, reports the following position end figures measured from a confirming unfiltered CCD image taken with a 0.36-m Schmidt–Cassegrain telescope on Oct. 16.163: 07s.46, 14".9. Another image obtained by Boles on Oct. 16.057 suggests that the object may have brightened slightly. A master image by Boles taken on Aug. 28 did not show the new object to limiting mag. 18.5. An image taken by Armstrong on 2000 Oct. 6 also shows nothing at the position of SN2001ew.
