On UT 2016-03-12 22:38 SNHunt reported to the TNS (Transient name server) a SN candidate at RA,DEC (J200) = [11:09:25.91, +29:34:25.68], which was designated the name AT 2016baq (=SNHunt313).

Two days later, on UT 2016-03-14 14:27, a transient was reported to the TNS by the ASAS-SN group at RA,DEC (J2000) = [11:09:25.76, +29:34:23.61], and was given the name AT 2016bcy (=ASASSN-16db); Atel #8813.

Since both objects relate to the same event, with a separation of 2.9 arcsec between the reported coordinates, object AT 2016bcy has been removed and the ASAS-SN report associated with AT 2016baq.

Based on additional analysis of the coordinates with respect to the USNO catalog, the revised coordinates of AT 2016baq are RA,DEC (J2000) = [11:09:25.79, +29:34:24.82].
