MASTER OT J024231.12+082526.7 - PSN

MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 02h 42m 31.12s +08d 25m 26.7s on 2014-11-11.64773 UT. The OT unfiltered magnitude is 17.8m (limit 19.5m). The OT is seen in 4 images. There is no minor planet at this place. We have reference image without OT on 2010-09-07.87279 UT with unfiltered magnitude limit 19.3m.

The OT is located 4" west and 7" south of the center of galaxy GALEX J024231.4+082534 (FUV=21.01+/-0.07 NUV=20.86+/-0.05) with unknown redshift. Spectral confirmation is required. This area of sky in Aries is not covered by SDSS. Color-combined DSS finder chart is uploaded to http://master.sai.msu.ru/static/OT/J024231+082526-BRIR.jpg (10'x10' FOV). The discovery and reference images by MASTER are available at: http://master.sai.msu.ru/static/OT/024231.12082526.7.png
