Vladimir Lipunov reports the discovery of a possible supernova by N. Tiurina using MASTER-Amur robotic telescope (0.40-m f/2.5 reflector + 4Kx4K CCD) and MASTER auto-detection system (MASTER-Net, http://observ.pereplet.ru) on the unfiltered survey images (60-sec exposures, limit 17.9m) obtained on 2014-01-24.822 UT. The new object of unfiltered magnitude 16.3m is located at R.A. = 12h26m08s.79, Decl. = +65o08'07".7 (J2000.0) which is 1" east and 2" north of the center of SDSS J122608.69+650805.7 galaxy (rmag=18.9). The object is seen in 2 images. We have reference image without OT on 2012-11-20.711 UT with unfiltered magnitude limit 18.3m. The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/122608.79650807.7.png (ref. ATel 5833, http://www.astronomerstelegram.org/?read=5833 )

V. Lipunov, N. Tiurina and D. Denisenko also report: we have obtained confirmation images of PSN J12260879+6508077 using the discovery MASTER-Amur telescope on Jan. 30.548-30.551 UT (180-sec exposures, limit 18.5m). Position end figures: 08s.81, 05".5; unfiltered magnitude 16.2m. Our images from Jan. 30 are posted at http://master.sai.msu.ru/static/OT/PSNJ122608+650805-MASTER-140130.png



2014 02 04.786

This transient was observed on 2014 02 04.786 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. 16.8 (R mags for the reference stars from UCAC-4). We also performed astrometry, getting the following end figures: 08.68; 05.0 (J2000.0, mean residuals of 0.2" on both axes).
