PSN J11571789+3624544 = SNhunt285. Object confirmed on stack of two 180-second luminance exposures taken with robotic telescope T18 (0.32-m f/8.0 astrograph + CCD) of iTelescope.net at AstroCamp Observatory in Nerpio, Spain. Object measured 19.0 +/- 0.3 with V as reference. Comparison stars were from the SDSS with g and r data used to determine V. Image: https://www.flickr.com/photos/watchingthesky/16806761598. S.

2015 04 02.84797

This transient was observed on 2015 04 02.84797 by G. Masi and P. Catalano, remotely using the 17"-f/6.8 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. 18.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 17.97; 56.0 (J2000.0, mean residuals of 0.1" on both axes).
