Аннотация:MASTER OT J032536.11-470150.6 discovery -short outburst with amplitude more then 7.2m
MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 03h 25m 36.11s -47d 01m 50.6s on 2019-06-20.37525 UT during survey.
The OT unfiltered magnitude is 14.8m (mlim=17.8m).
The OT is seen in 2 image. There is no minor planet at this place.
Preliminary photometry is the following
Date_Time_UT m_OT mlim
2019-06-20 08:49:00UT 17.3 17.7
2019-06-20 09:00:22UT 14.8 17.8
There is no any sources in VIZIER database, it means 22m POSS limit in history and more then 7.2m of current outburst amplitude
We have reference image without OT on 2016-10-27.33397 UT with unfiltered magnitude limit 20.9m, 2019-04-11 23:46:04 with mlim=18.4 (the nearest in time in MASTER-OAFA), on 2019-06-19 02:39:33 with mlim=18.0 (the nearest in time in MASTER-SAAO).
There is no publishied Fermi, Swift, IceCube, LIGO/Virgo alerts at this time.
Deep photometry is required.
