OT MASTER J091744.35+403206.5 - PSN in SDSS J091744.29+403206.9

MASTER-Tunka auto-detection system discovered OT source at (RA, Dec) = 09h 17m 44.35s +40d 32m 06.5s on 2012-04-15.61514 UT. Astrometric error is about 0.5 arcsec. The OT unfiltered magnitude is 18.4m (limit 20.2m). The OT is seen in 4 images. There is no minor planet at this place. There is SDSS galaxy J091744.29+403206.9 with 0.9 arcsec offset.

We have reference image without OT on 2012-02-01.86223 UT with unfiltered magnitude limit 19.9m.

Spectral observations are required.
