Yuan, University of Michigan et. al., report on The Astronomer's Telegram 2128 the discovery of a SN candidate, ROTSE3 J203837.4-250656, on unfiltered CCD images taken on 2009 Jul 11.90 UT with the 0.45-m ROTSE-IIIc telescope at the H.E.S.S. site in Namibia. The transient was detected at about 17.0 magnitude on both Jul 11.90 UT and Jul 12.89 UT. It is located at: RA 20h 38m 37.42s DEC -25o 06' 56.0" (2000), which is 26" west and 33'' north to the centre of galaxy MCG-04-48-026. No source was detected at this location in the DSS2 images and the ROTSE-III reference image (limit ~19.3 mag)constructed from images taken between Jun. 2008 and Aug. 2008. A finding chart of the transient is posted at the following website URL: http://www.rotse.net/rsvp/j203837.4-250656/j203837.4-250656.jpg The transient is slightly blended with an object (R~18.2 in USNOB 1.0) to its southeast in the ROTSE-III images.

SUPERNOVA 2009ft IN ANONYMOUS GALAXY Discovery by the CRTS of a possible supernova (CBET 1830): SN 2009 UT R.A. (2000.0) Decl. Mag.

Silverman et. al., University of California at Berkeley, report that inspection of CCD spectra of May 28 UT with the 3-m Shane reflector (+ Kast) at Lick Observatory, reveals it to be a normal type-Ia supernova about one week past maximum brightness.
