MASTER OT J014035.40+211544.2 - PSN in SDSS8 J014035.33+211548.3 galaxy

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 01h 40m 35.40s +21d 15m 44.2s on 2013-02-02.69083 UT. The OT unfiltered magnitude is 18.9m (limit 19.2m). The OT is seen in 2 image. There is no minor planet at this place. We have reference image without OT on 2010-11-03.82112 UT with unfiltered magnitude limit 20.0m. There is SDSS8 J014035.33+211548.3 galaxy (r_mag=20.3) with 4.5 arcsec offset.

Spectral observations are required.

MASTER OT J205908.67+802217.6 - CV

MASTER-Amur auto-detection system discovered OT source at (RA, Dec) = 20h 59m 08.67s +80d 22m 17.6s on 2013-01-27.74699 UT. The OT unfiltered magnitude is 16.2m (limit 17.1m). The OT is seen in 2 images. There is no minor planet at this place. We have reference image without OT on 2013-01-14 11:58:20 UT with unfiltred magnitude limit 18.8 m. There is no source in any catalogs at this place.

Follow up observations are required.

MASTER OT J020826.17 +085836.4 - flare of the AGN or Blazar

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 02h 08m 26.17s +08d 58m 36.4s on 2013-02-02.69509 UT. The OT unfiltered magnitude is 17.0m (limit 18.9m). There are several catalogs ( GB6 catalog of radio sources (Gregory+ 1996); SPECFIND V2.0 Catalog of radio continuum spectra (Vollmer+ 2009)) with objects close to OT (offset = 1.5 arcsec). So, OT is active state of the AGN or BL Lac.

We have reference image without OT on 2011-08-12 00:34:56 UT with unfiltered magnitude limit 19.3 m.

Spectral observations are required.
