2015 01 24.479

PSN J11105565+5322493 = SNhunt273. UGC 6215 = NGC 3549. This transient was confirmed on 2 x 120-second luminance exposures taken on 2015 January 24.479 with remote robotic instrument T24 (0.61-m f/6.5 astrograph + CCD) of iTelescope.net in Auberry, California. Photometry of 17.56 +/- 0.07 was determined using V as reference. Comparison stars are from UCAC4. Image: https://www.flickr.com/photos/watchingthesky/16329729656. S. Howerton

Object is confirmed on an unfiltered image taken by B. Lütkenhöner, using Slooh Space robotic telescope T2, 0.35m F/11 Schmidt Cassegrain, Mt Teide, Canary Island. Mag = 17.5, V for ref. Image : https://www.flickr.com/photos/econseil/16366931835/




2015 01 26.97334

This transient was observed on 2015 01 26.97334 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. 120-seconds exposures, unfiltered, show the source at mag. 17.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 55.73; 54.4 (J2000.0, mean residuals of 0.2" on both axes).
