MASTER OT J000008.72-334156.5 discovery near the PGC143111 galaxy
MASTER-IAC auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 00h 00m 08.72s -33d 41m 56.5s on 2015-10-13.98017 UT.
The OT unfiltered magnitude is 17.6m (the limit is 19.9m).
The OT decay is seen in 3 images during 22 minutes from 17.6 up to 19.8. There is no minor planet at this place. We have reference image without OT on 2015-07-14.939 UT with unfiltered magnitude limit 20.7m in MASTER-SAAO database.
There is PGC143111 galaxy. The OT offset is 3.3"W and 21"S.
Deep observations are required.
There were no detection at this time at SWIFT, MAXI, INTEGRAL and Konus-Wind(up to this moment).
The nearest in time alert was Fermi GBM (15/10/13 12:15:46.20 RA=114.733,-36.833,ErB=7.33) , but it is too far from OT.
There is only W-mags from WISE in VIZIER database, but no JHK. CRTS observed this area, but didn't see any source (and POSS too).
there are 3 possibilities: to be an orphan in PGC143111, to be an UVCet in MW (but the amplitude is too high for it), and a OT of unknown nature. So the mankind needs deep obervations.
