PSN J21055667-1236089 = SNhunt251. Object measured 16.82 +/- 0.05 clear with V as reference on a single 180 second clear image obtained with the 0.43m robotic telescope T17 of iTelescope.net in Siding Spring, Australia. Comparison stars are from UCAC4. Image: https://www.flickr.com/photos/watchingthesky/14114724539. S. Howerton

This transient was observed on 2014 06 01.0062 by Gianluca Masi, 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. 180-seconds exposures, unfiltered, show the source at mag. 17.5 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 56.70; 07.9 (J2000.0, mean residuals of 0.2" on both axes).
