Object confirmed on single 180 second luminance image taken with the 0.5m robotic telescope T11 (iTelescope.net) in Mayhill, NM. Photometry of 18.3 +/- 0.1 was determined using V as reference. Comparison stars were from SDSS whose g and r data were calculated to V. S. Howerton. Image: https://www.flickr.com/photos/watchingthesky/14005292111/

2014 04 26.889

this transient was observed on 2014 04 26.889 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. 18.0 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 11.31; 13.4 (J2000.0, mean residuals of 0.2" on both axes).
