It was first recorded on an unfiltered CCD image of Aug 20.112UT and subsequently confirmed on Aug 21.069UT using a 0.35-m reflector during the course of the UK Nova/Supernova Patrol. The new object is located at RA 02h 48m 58.39s DEC +03 10' 07.6" (2000), 6.4"W of the centre of host galaxy. The suspect is not present on Tom's images of 2003 Jan 7 and 2003 Feb 17 (limiting mag 19.0) and it is not on Palomar Sky Survey red (1990.733) or blue plates (1992.883) The object was designated SN 2003hm and announced on IAUC 8185. Congratulations to Tom, who with this discovery, has reached his 50th find! PECULIAR OBJECT IN CRUX V. Tabur of Wanniassa has noted a variable object on images taken with a 140-mm f/2.8 Nikon telephoto lens of 2003 August 20.486 and 20.490UT. The object, located in Crux, was of magnitude 10.2 and located at: RA 12h 23m 16.2s DEC -60 22' 34" (2000). Andrew Pearce, Western Australia, has e-mailed to advise that he has confirmed the object visually using a 0.20-m reflector. Using Tycho 2 comparison star magnitudes, he estimated the object at magnitude 10.2 on Aug 22.493UT. According to Tabur, the object is not visible on a number of exposures going back to January 2000 and it is also not visible on the Palomar Sky Survey implying a large amplitude. According to a note on IAU Circular 8185, H. E. Bond, Space Telescope Science Institute, reports that spectra obtained with the SMARTS Consortium 1.5-m telescope at Cerro Tololo by S. Gonzalez on Aug. 21.95 UT, appear to confirm that the object is a classical nova. However M. Della Valle, Osservatorio Astrofisico di Arcetri, Florence et. al., find that spectrum obtained on Aug 22.02UT with the ESO 3.6-m telescope at La Silla suggests a lack of typical signatures exhibited by Fe- or He/N-type classical novae in their early evolution. Their preliminary analysis suggests this object may not to be a classical nova, but possibly a post-asymptotic- giant-branch star in flare-up, a V4332 Sgr-type object or a V838 Mon-type object caught at an early stage. SUPERNOVA 2003hh In UGC 12890 A possible supernova has been reported by the LOTOSS team as detected in UGC 12890 according to IAU Circular 8184: SN 2003 UT R.A. (2000.0) Decl. Mag. Offset 2003hh Aug. 18.5 0 00 07.08 +08 16 42.3 18.7 0.4"E, 2.9"S On August 8.5, the object had not been recorded to a limit of 19.5 by the LOTOSS team. SUPERNOVA 2003hl IN NGC 772 A further LOTOSS report of a supernova, this time in NGC 772, also appeared on IAUC 8184: SN 2003 UT R.A. (2000.0) Decl. Mag.
