A confirming image of PSN J21372712-4701548 was taken at Parkdale Observatory New Zealand on the 26th.Images clearly showed the new PSN on many 100 second images taken with a 12 inch RC and ST10 camera. Magnitude was still around 16.5 but due to seeing conditions measuring was difficult

This object was confirmed by P. Miller, P. Roche, A. Tripp, R. Miles, R. Holmes, S. Foglia, L. Buzzi, T. Vorobjov and T. Lister with the 2.0-m f/10 Faulkes Telescope South at Siding Spring, Australia. A single, R-Bessell filtered, 120-seconds image shows the PSN with position end figures 27s.12, 55".8, and R-mag 15.5.

Elias-Rosa (nancy.elias@oapd.inaf.it) Subjects: Optical, Supernovae PESSTO, the Public ESO Spectroscopic Survey for Transient Objects (see Valenti et al., ATel #4037; http://www.pessto.org ), reports the following supernova classifications. Targets were supplied by the CHASE, the La Silla-Quest survey (see Hadjiyska et al., ATel #3812), Pan-STARRS1 (www.ps1sc.org), and the Catalina Real-time Transient Survey (http://crts.caltech.edu/). All observations were performed on the ESO New Technology Telescope at La Silla on 2013 October 26, using EFOSC2 and Grism 13 (3985-9315A, 18A resolution). Classifications were done with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024) and GELATO (Harutyunyan et al., 2008, A&A, 488, 383). Classification spectra can be obtained from http://www.pessto.org (via WISeREP). Name | RA (J2000) | Dec (J2000) | Disc. Date | Disc.
