The MASTER Amur auto-detection system at Blagoveschensk detected a new transient source as the SN candidate at the position (R.A., Dec) = 07h 36m 42.49s , +74d 26m 35s.1 (J2000) with a typical uncertainty of 0.5" ( offset 21.5E 12.4S from PGC021381 galaxy) at 2010-02-13.54 (UT). The OT is seen at next image (40 min delay). We have several older images without OT. There is another galaxy - PGC021386 nearby OT. We cannot choice host galaxy between PGC021381 and PGC021386, because its have same redshift and same distances from OT. May be this is interaction galaxy systems.

There is no minor planet and any object brighter 20 mag in SDSS at this place.

The V-band magnitude is about 13.9 +-0.1 ( exposition 180s, image limit is 18.0).

The spectral observations are needed.
