MASTER OT J054018.25-230833.0 discovery - short transient, possibly PSN in 2.2"W,0.3"S of PGC147719
AT2021lkg
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 05h 40m 18.25s -23d 08m 33.0s on 2021-05-05.72698 UT.
The OT unfiltered magnitude is 16.9+-0.1m (automatically detected value), mlim=18.9.
The OT is seen in 3 image. There is no minor planet at this place.
We have reference image on 2020-07-19.17773 UT with unfiltered mlim= 19.5m.
This OT is in 2.2"W,0.3"S of edge-on PGC147719 galaxy
Spectral observations are required.
