M. A. Garcia Borrella –Observatorio SPAG Monfragüe MPCJ07, Caceres, Spain- and J.L. Gonzalez Carballo –Badajoz, Spain- report that on unfiltered CCD images obtained on October 29.908 UT with a 0.4m Catadioptric Telescope + CCD STL11000 camera have noted a point-like source at A.R. =01h07m15s.47, Dec =+32º31’10”.1 (equinox 2000.0, astrometry with respect UCAC-3 stars) wich is 4 arcsec South and 4 arcsec East of the center of Galaxy NGC379. The point like source unfiltered magnitude is 16.8 (limiting magnitude = 21.1) with respect to CMC14 field stars. The source is not present on the digitized plates of the POSSII-R survey (1989-10-28, limiting magnitude = 20.3) and POSSII-B survey (1989-09-17, limiting magnitude = 20.3).

This transient was observed on 2013 10 31.877 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. 16.1 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 15.46s 10.9" (J2000.0, mean residuals of 0.2" on both axes).

This possible supernova in NGC 379 was detected with 3 x 15 min images using a clear filter Photometry: Mag 16.43 +/- 0.13 C (V for ref) Astrometry: RA 01 07 15.45 Dec +32 31 10.0 These data were collected by Joseph Brimacombe, Cairns, Australia.

This transient(mag.+16.7)is a field star visible in several unfiltered images taken during my SN search (0.35m. Sch-Cass. F/5.5 + SXVR H9 ccd camera;40 sec. exposure), and is not clearly visible in many reference images (POSS I - II red and blue - SDSS and others).
