As Nick James and Denis Buczynski will also be there special arrangements have been made with regard to monitoring for discoveries. During that period, in the event of a very urgent message or discovery please telephone the editor with brief details on the following mobile telephone number: (07905) 332226 IN ADDITION please ensure a message with fuller details is copied to BOTH the Demon and Rutherford mailboxes at the addresses shown in the circular header. SUPERNOVA 2001en IN NGC 523 An independent discovery of this supernova (discovery on E-Circular 1695) at Beijing Astronomical Observatory has been relayed from Wan Zhou via W. Li. The Beijing group found SN 2001en on an exposure taken on Sept. 27.53 UT at mag about 17.4. Its position end figures were found to be 22s.82, 30".2 (equinox 2000.0). Nothing was visible on a Beijing image obtained on Sept. 12.64 (limiting mag 18.2). IAUC 7725 (extract) Mark Armstrong, Rolvenden, has also e-mailed to confirm he found this object on an image of 2001 Sept 29 (22.58UT) before seeing the relevant IAU Circular. POSSIBLE NOVA IN CENTAURUS Since the note on TA E-Circular 1695, this object has also been announced on IAUC 7726. A. C. Gilmore, Mount John Observatory, University of Canterbury, reports the following photoelectric photometry of the new object obtained with the 0.6-m f/16 reflector under marginal conditions (thin cloud, bright moonlight); reference stars were Cousins F218 and F212: Oct. 2.415, V = 9.11, U-B = +0.83, B-V = +1.41, V-R = +0.81, V-I = +1.69, airmass 2.18. Gilmore provides the following position with uncertainty < 10" in each coordinate (proper astrometry not possible due to lack of reference stars in the moonlight): R.A. = 13h55m41s.9, Decl. = -64o15'48" (2000). SUPERNOVA 2001eo IN UGC 3963 T. Puckett and M. Marcus, Mountain Town, GA, report the discovery of an apparent supernova (mag 17.5) on an unfiltered CCD frame (limiting mag 19.0) taken with the Puckett Observatory 0.30-m automated patrol telescope on Oct. 1.38 UT. SN 2001eo is located at R.A. = 7h41m31s.10, Decl. = +51o41'05".4 (equinox 2000.0), which is 10".0 west and 13".5 south of the center of UGC 3963. The new object was confirmed on CCD frames taken on Oct. 2.34 by Marcus (0.60-m reflector). IAUC 7726 (extract) Guy M Hurst
