Аннотация:MASTER OT J050321.63-284353.2 discovery - PSN in 5.2E,14.5N of PGC738093
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 05h 03m 21.63s -28d 43m 53.2s on 2018-08-31.06248 UT.
The OT unfiltered magnitude is 17.5m(mlim=20.1).
PSN is seen in 6 images. There is no minor planet at this place.
We have reference images on 2015-02-17.87686 UT with unfiltered mlim=21.2m, 2017-10-14 21:25:24UT with mlim=20.0.
Spectral observations are required.
