Balaji Kumar report/s the discovery of a new astronomical transient.
IAU Designation: AT 2026iul
Discoverer internal name: GEOTS-PAPA-SHANKAR-2026-003
Coordinates (J2000): RA = 19:51:44.150 (297.933958) DEC = +31:28:49.50 (31.480417)
Discovery date: 2026-04-07 09:31:39.936 (JD=2461137.89699)
Remarks: Discovered in Cyg using 14" f/2.0 Astrograph at Golden Ears Observatory (MPC code U55). We report a significant brightening of the Gaia DR3 variable star 2033708559892804224 (VSX). Recent observations show an increase in magnitude of >2.3 when compared to the last recorded observation from Golden Ears Observatory on 02 March 2026.
