PSN J09582423+5604456   2013 11 20.76  *  09 58 24.23 +56 04 45.6  18.7 U    1E   5N            9 9

2013 11 20.76

We discovered this object on Nov.20.76 2013 UT in galaxy SDSS J095824.23+560440.8 in the Tsinghua University-NAOC Transient Survey (TNTS), and the magnitude of the object on unfiltered CCD was about 18.7 mag.

L. Elenin (Lyubertsy, Russia) and I. Molotov (Moscow, Russia) confirm an apparent supernova PSN J09582423+5604456 in IC 1342. Object visible on 3x150sec images remotely taken at ISON-NM Observatory (Mayhill, NM, USA) with 0.4-m f/3 telescope + CCD (KAF09000) on Nov. 26.3572, 2013. Object located at 09h 58m 24s.23 +/- 0".08, 56d 04' 44".2 +/- 0".07 (UCAC-4) with magnitude 18.3R (mag. limit ~19.9R). Nothing is visible at this position on POSS and POSSII images.

2013 11 27.156

This transient was observed on 2013 11 27.156 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 robotic unit part of the Virtual Telescope Project facility in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 18.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 24.23s; 44.9" (J2000.0, mean residuals of 0.2" on both axes).

2013 11 26.443

This possible supernova in USNOA2 1425-07418378 was detected with 5 x 10 min images using a clear filter Photometry: Mag 19.45 +/- 0.42 C (V for ref) Astrometry: RA 09 58 24.24 Dec +56 04 45.5 These data were collected remotely by Joseph Brimacombe, Cairns, Australia.
