The last message seen was received May 13 at 20:41. Until further notice please send mail to my Cambridge box as detailed in the heading of this circular. I can read incoming messages at that site although there may be a delay in replying. As a precaution during this period, in addition to sending to Cambridge please also copy any DISCOVERY messages to Gary Poyner on BHVAD::GP (Starlink and SPAN) or gp at uk.ac.bham.sr.star on Janet. SUPERNOVA 1993M IN ANONYMOUS GALAXY J. Maza, University of Chile; and M. Hamuy, Cerro Tololo Interamerican Observatory, report the discovery of an apparent supernova of mpg about 18.5 by R. Antezana (University of Chile) on a 20-min unfiltered IIa-O plate taken by G. Valladares with the CTIO Curtis Schmidt telescope on Apr. 28.33 UT. The new object is located 1" west and 3" south of the nucleus of a galaxy at R.A. = 19h08m16s, Decl. = -64 22'29" (equinox 1950.0). Confirmation of SN 1993M was made by R. Aviles on CCD B, V, and I images obtained on May 2.279 with the CTIO 0.9-m telescope. IAUC 5783 SUPERNOVA 1993N IN UGC 5695 J. Mueller reports her discovery of an apparent supernova located 6".7 west and 9".4 north of the nucleus of UGC 5695 (R.A. = 10h27m.1, Decl. = +13 16', equinox 1950.0). The new object was found at mag about 17.5 on a blue plate taken Apr. 15 by C. Brewer and Mueller with the 1.2-m Oschin Schmidt Telescope in the course of the second Palomar Sky Survey. E. Cappellaro and M. Della Valle, European Southern Observatory, communicate: "CCD frames obtained on May 6.1 UT at the 1.5-m Danish telescope at La Silla confirm the presence of the new object 6".8 west and 9".8 north of the nucleus of UGC 5695. Preliminary photometry gives: V = 18.6, B-V = +0.5, V-R = +0.7." IAUC 5784 SUPERNOVA 1993J IN NGC 3031 There is a suggestion from very recent data that the light curve of this supernova is entering yet another interesting phase. We do not wish to publish data at this stage in our continuing effort to avoid bias but could we appeal for intensive coverage on every clear night please. For the results so far logged, (discovery until May 8) not a single night has passed without at least one observation which represents a very fine achievement by our worldwide team of observers. FINDERS The announcement on E739 should have made it clear that FINDVGA.EXE works on VGA as well as Super VGA Monitors.
