MASTER OT J132500.30-295850.5 discovery - PSN in 0.2"W, 2"N of PGC722880 inside NS+BH LVC S191205ah error-field
AT2019xtt
MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 13h 25m 00.30s -29d 58m 50.5s on 2019-12-22 04:42:28.818 UT.
The OT unfiltered automatic magnitude is 17.6m, mlim=19.7.
The OT is seen in 6 images, including 2019-12-23 04:32:57U, 2019-12-24 04:36:39UT. There is no minor planet at this place.
We have reference images without PSN on 2019-04-09 01:49:12UT with unfiltered mlim=19.9.
Spectral observations are required.The distance for the galaxy is unknown.
This SN is inside NS+BH LVC_S191205ah error-field (LVC GCN #26350, distance 385 +/- 164 Mpc,
MASTER inspect Lipunov et al. GCN #26353, GCN #26379, MASTER cover map)
