MASTER OT J073857.06+182648.2 discovery - the first days of PSN in Sloan galaxy nuclei
MASTER-IAC auto-detection system ( Lipunov et al., "MASTER Global Robotic Net",
Advances in Astronomy, 2010, 349171 ) discovered OT source at (RA, Dec) = 07h 38m 57.06s +18d 26m 48.2s on 2015-12-17.01177 UT.
The OT unfiltered magnitude is 17.8m (the limit is 19.9m).
The OT is seen in 5 images (2015-12-17 00:13:07.828 - 00:35:23.004 UT).
We have reference image without PSN on 2015-12-03.14234 UT with unfiltered magnitude limit 19.5m, and on 2015-12-12.0924 UT with unfiltered m_lim=20.3 and m_galaxy~20.2
Spectral observations are required.
This PSN is in 0.4arcsec from the Sloan galaxy
