MASTER OT J121900.03-465048.7 discovery - less then 5 days old PSN in 12.3E,16S of bright spiral ESO267-040
MASTER-SAAO auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L )
discovered OT source at (RA, Dec) = 12h 19m 00.03s -46d 50m 48.7s on 2019-04-07.92551 UT.
The OT unfiltered magnitude is 18.0m (mlim=19.8).
The OT is seen in 3 images (preliminary automaatic photometry):
Date_UT, unfiltered_magnitude
2019-04-06 21:58:43.789 18.8 +-0.1
2019-04-07 22:12:44.167 18.0 +-0.1
2019-04-07 22:23:51.327 18.0 +-0.1
We have reference images on 2019-04-01 21:15:38UT with mlim=20.0, on 2017-04-28.80844 UT with unfiltered mlim= 20.1m.
Spectral observations are required.
