MASTER 113122.95-075714.5 - Rapid Transient

MASTER-Kislovodsk auto-detection system discovered short OT source at (RA, Dec) = 11h 31m 22.95s , -07d 57m 14s.5 on 2012-01-30 00:05:11.145.

The OT unfiltered magnitude is 17.6m (limit 19.3m). The OT is seen in 2 synchronous images (MASTER – is the double telescope).

There are no minor planet, sattelite and any object at this place.

The last reference image without OT was at 2012-01-29 23:21:06UT with unfiltered magnitude limit 19.4m .

The OT is seen on two synchronous images. There are no minor planet or star at this place. There are no GRB events from Swift, Fermi, INTEGRAL, Wind-KONUS at this time.

The discovery and reference images are available at: http://observ.pereplet.ru/images/113122.95-075714.5/MASTER113122.95-075714.jpg

The deep follow up image is required.

MASTER OT221306.74+581605.9 - Variable
