Constantine Emmanouilidi report/s the discovery of a new astronomical transient.

IAU Designation: AT 2016brz
Coordinates (J2000): RA = 14:37:14.730 (219.311375) DEC = +38:27:24.60 (38.456833)
Discovery date: 2016-04-22 02:09:36 (JD=2457500.59)

Potential host galaxy: NGC5698
Host redshift: 0.012272

Remarks: GSST/Constantine Emmanouilidi/Emelie Selander report a possible supernovae explosion that shows up on all of the three consecutive images made during the automatic survey for supernovae. We cannot confirm the find with another observatory and the remotely controlled ones aren't available at the time writing this report so follow up observations are needed. There is no known object at the specific coordinates in the TNS database nor any comets/asteroids reported from MPChecker during the time of observation. The object follows the convolution pattern of the local seeing conditions and doesn't appear to move between the three 15sec exposures made and cannot be found in any survey images from DSS. Star catalogue USNO A2 doesn't show any known stars at the coordinates of the suspect either.
