OT MASTER134201.21-023856.2 - PSN

MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 13h 42m 01.21s -02d 38m 56.2s on 2012-04-21.88875 UT. The OT unfiltered magnitude is 19.4m (limit 20.5m). The OT are seen in 2 images. There is no minor planet at this place. There is SDSS galaxy J134201.15-023854.4 whith 2 arcsec offset. We have reference image without OT on 2011-01-13.10411 UT with unfiltered magnitude limit 22.1m.

Spectral observations are required.
