Discovered through CRTS SNHunt (Drake et. al)

2014 3 26.158

Confirmed on stack of 83x20 second unfiltered images with 0.28m f/5 SCT in Arkansas City, Kansas. Photometry 18.5U with V as reference using comparison stars from SDSS where V was calculated from g and r. S. Howerton

This transient was observed on 2014 03 28.836 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. 18.9 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 10.04; 25.1 (J2000.0, mean residuals of 0.2" on both axes).
