MASTER OT J165346.56+164948.6 - new short Flare of the QSO source CSS080426 J165347+164950

MASTER-Kislovodsk auto-detection system (Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010) discovered OT source at (RA, Dec) = 16h 53m 46.56s +16d 49m 48.6s on 2015-02-27.06422 UT.

The OT unfiltered magnitude is 18.5m (the limit is 20.2m).

The OT is seen on 4 images. There is no minor planet at this place.

We have reference image without OT on 2010-04-16.97389 UT with 20.0 unfiltered magnitude limit.

The discovery and reference images are available at: http://master.sai.msu.ru/static/OT/MASTERJ165346.56+164948.6.jpg

Spectral observations are required.

MASTER OT J104706.90+002936.5 - QSO flare

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 10h 47m 06.90s +00d 29m 36.5s on 2015-02-26.81303 UT. The OT unfiltered magnitude is 18.1m (the limit is 19.1m).

The OT is seen in 5 images. There is no minor planet at this place.

We have reference image without OT on 2010-12-07.122 UT with 21 unfiltered magnitude limit.

This OT is identical to 43410 source from NBC Quasar Candidate Catalog (Richards+, 2004) with rmag=20.652.

Spectral observations are required.
