MASTER-SAAO auto-detection system ( Lipunov et al., Advances in Astronomy, MASTER Global Robotic Net, 2010 ) discovered OT source at (RA, Dec) = 08h 01m 39.75s +15d 44m 01.9s on 2015-05-27.69359 UT.
The OT unfiltered magnitude is 15.4m (limit 17.6m).
The OT is seen in 10 images. There is no minor planet at this place.
This PSN is in in 36.2"E and 86.4"N from the NGC2507 galaxy.
We have reference image without OT on 2015-04-28.76987 UT with unfiltered magnitude limit 17.7m.
Spectral observations are required.
