We discovered this object on Nov.18.83 2013 UT in the Tsinghua University-NAOC Transient Survey (TNTS), and the magnitude of the object on unfiltered CCD was about 19.1 mag.

2013 11 27.147

This transient was observed on 2013 11 27.147 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. 18.5 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 01.57s; 36.0" (J2000.0, mean residuals of 0.2" on both axes).
