MASTER OT J104115.34+373321.8 - Bright PSN in PGC2103473

MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 10h 41m 15.34s +37d 33m 21.8s on 2012-11-20.77446 UT. The OT unfiltered magnitude is 16.7m (limit 18.3m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2012-10-28.87917 UT with unfiltered magnitude limit 18.4m. The OT detected near PGC2103473 galaxy with 17.7W and 25.2N offset. Spectral observations are required.

MASTER OT J100950.32+471815.8 - CV ? MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 10h 09m 50.32s +47d 18m 15.8s on 2012-11-20.97971 UT. The OT unfiltered magnitude is 18.0m (limit 19.8m). The OT is seen in 5 images. There is no minor planet at this place. There is no object in catalogs around 20 arcsec. We have reference image without OT on 2009-10-12.09537 UT with magnitude limit in 'R' filter 18.8m.

Follow up observations are required.
