2014 02 19.60

We discovered this object on Feb.19.60 2014 UT in the Tsinghua University-NAOC Transient Survey (TNTS), and the magnitude of the object on unfiltered CCD was about 18.0 mag. Discovery and reference images: http://www.thca.tsinghua.edu.cn/~wangxf/TNTS/PSNJ07564406+4549502.png

2014 02 21.907

This transient was observed on 2014 02 21.907 by Gianluca Masi, Francesca Nocentini and Patrick Schmeer, remotely using the 17"-f/6.8 corrected Dall-Kirkham robotic unit part of the Virtual Telescope Project facility, at Bellatrix Astronomical Observatory in Ceccano, Italy. 120-seconds exposures, unfiltered, show the source at mag. 17.6 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 44.09; 49.9 (J2000.0, mean residuals of 0.2" on both axes).
