Villalobos, L.H.Rodriguez (INAOE, Guillermo Haro Astrophysics Observatory) MASTER-Tavrida robotic telescope of MASTER Global Robotic Net [1-4] started GOTO26djh/AT2026jpw (discovered by GOTO O'Neill et al., GCN 44301, also observed by NOT (Corcoran et al., GCN 44303) and Zeiss-1000 at SAO RAS (Moskvitin et al. GCN 44304) observations at 2026-04-15 23:10:27UT. There is optical transient at summary MASTER image (2520s exposition, mlim=22.2m) with unfiltered m_OT~21.5+-0.6m , calibrated by Pan-STARRs stars in our field. MASTER images are available on request. Observation and reduction will continue.
