MASTER093143.32-233742.3 discovery - Flares of red star?

MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 09h 31m 43.32s -23d 37m 42.3s on 2019-05-02.00845 UT. The OT unfiltered magnitude is 16.6m (mlim=18.5m).

The OT is seen in 2 images. There is no minor planet at this place.

We have reference image without OT on 2017-03-27.13828 UT with magnitude limit 20.1m unfiltered.

Spectral observations are required.

The discovery and reference images are available at:

The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2014-07-19.70703 UT with unfiltered magnitude limit 20.2m.

No known object on this place.

Spectral observations are required.

MASTER OT J121900.16-465047.9 discovery - PSN in ESO267-040 galaxy

MASTER-OAFA auto-detection system ( Lipunov et al., "MASTER Global Robotic Net", Advances in Astronomy, 2010, 30L ) discovered OT source at (RA, Dec) = 12h 19m 00.16s -46d 50m 47.9s on 2019-04-30.08267 UT. The OT unfiltered magnitude is 17.3m (mlim=19.0m). The OT is seen in 7 images. There is no minor planet at this place. We have reference image without OT on 2018-06-15.08874 UT with magnitude limit filter 19.8m unfilterd. There is ESO267-040 galaxy with 14E and 15.2S offset.

Spectral observations are required.
