MASTER OT J222232.87-185224.3 discovery - possible SN in IC5210

MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 22h 22m 32.87s -18d 52m 24.3s on 2015-06-14.08992 UT.
The OT unfiltered magnitude is 17.8m (the limit is 20.0m). This PSN is in 25.2"E 13.3"S from the center of IC5210.
There are 5 images with this PSN. There is no minor planet at this place.
We have reference image without OT on 2015-04-01.15545 UT with unfiltered magnitude limit 18.8m.

Spectral observations are required.

MASTER OT J214018.02-070410.7 discovery - possible SN in PGC1024917

MASTER-SAAO auto-detection system discovered OT source at (RA, Dec) = 21h 40m 18.02s -07d 04m 10.7s on 2015-06-12.05168 UT.
The OT unfiltered magnitude is 17.9m (the limit is 19.5m).
The OT is seen in 9 images. There is no minor planet at this place.

We have reference image without OT on 2015-04-25.09598 UT with unfiltered magnitude limit 19.2m.

Spectral observations are required.
