Constantine Emmanouilidi, Emelie Selander for the GSST report/s the discovery of a new astronomical transient.

IAU Designation: SN 2016bme
Coordinates (J2000): RA = 08:56:45.000 (134.1875) DEC = +52:07:01.00 (52.116944)
Discovery date: 2016-04-12 19:10:54 (JD=2457491.2992361)

Potential host galaxy: UGC4671

Remarks: The Greek Supernovae Survey Team reports this possible SN explosion in galaxy UGC4671. The new object doesn't appear to move on four diiferent images made during the search and a seach in MPChecker doesn't show any know asteroids of coments in the area. We tried to obtain remote control observations from Mexico and Australia but weather doesn't permit any. The place of the newly found object was searched also for stars from USNO A2 catalogue and nothing was recorded there as well. Astrometry calculations were made from the web page www.astrometry.net and the images were compared in Aladin java applet from CDS. I've searched throught the AT list in TNS and also the web page Bright Supernovae doesn't report any PSN in that area as well.
