MASTER OT J030831.72-161514.1 discovery - PSN in PGC900542
MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",
Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 03h 08m 31.72s -16d 15m 14.1s on 2018-08-09.20596 UT
during Fermi 555263883 trigger inspection (TriggerTime=2018-08-06 15:57:58.30UT , https://gcn.gsfc.nasa.gov/other/555263883.fermi )
The OT unfiltered magnitude is 17.5m (mlimit=19.1m).
The OT is seen in 3 images: 2018-08-09 04:48:31,04:56:35,05:11:31UT .
There is no minor planet at this place.
We have reference image without OT on 2015-11-16.84648 UT with 19.2m unfiltered magnitude limit .
This PSN is in 1.3"E,7.8"S of PGC900542 (Btc=17.06,Itc=15.61 http://leda.univ-lyon1.fr/ledacat.cgi?PGC900542 )
Spectral observations are required.
