The object, of magnitude 17.7, was imaged on Apr 03.932UT using a 0.35-m Schmidt-Cassegrain telescope from which a precise position was derived: RA 06h 12m 03.50s DEC +51 52' 03.3" (2000), 0.9"W and and 12.0"N of the centre of the host galaxy. The suspect is not present on Tom's images of 2004 Nov 20 and 2005 Jan 05 (limiting mag 19.5) and it is not present on DSS II red (1989.924 limiting mag 21.0) nor on blue plates (1992.900 limiting mag 20.5) A further e-mail received later on April 4 advised that a confirmatory image had been obtained on Apr 4.849UT with end figures: RA 03.52s DEC 03.3" (2000) The supernova was subsequently announced on IAUC 8505 and designated Supernova 2005bd. Congratulations to Tom on the discovery of his 87th supernova. V378 SERPENTIS (=POSSIBLE NOVA IN SERPENS) G. Pojmanski has reported on IAUC 8505 the ASAS discovery of a possible nova located at: RA 17h 49m 24s, DEC -13 00' 00" (2000). V magnitudes: 2005 Mar. 14.39UT, [14; 18.35, 13.3; 21.37,11.8; 27.35, 12.7. G. Masi, University of Rome reports a precise position from CCD images of Apr 4.35UT using the 0.36-m SoTIE telescope at Las Campanas: RA 17h 49m 24.57s DEC -12 59' 59.2" (2000) Astronomers at the Insitute of Astronomy, Russian Academy of Sciences, Moscow, advise that the designation V378 Serpentis has been given to this object. According to a report from observers at the European Southern Observatory, a spectrum obtained on April 5.38UT with the 2.2-m telescope at La Silla confirm the object is a 'Fe II' nova. A spectrum by M. Fujii in Japan also suggests it is 'somewhat after maximum light'. CI GEMINI Patrick Schmeer, Germany reports that he has detected an outburst of CI Gemini on unfiltered CCD images obtained with the University of Iowa, Rigel telescope (0.37-m Cassegrain): 2005 Apr 11.119, <185CR; Apr 12.128, 150CR He adds that outburst looked like a short outburst of an SS Cyg-type dwarf nova. Precise coordinates: RA 06h 30m 05.86s DEC +22 18'50.7" (2000) Gary Poyner adds that the last observed outburst occurred on 1999 Feb 18, when Schmeer again picked it up with the same telescope at 15.8C.
