The new object approximately located at R.A.=10h 55m 53s.83 Decl.=+36 51 48.0(equinox 2000.0). Nothing is visible at this position on archival images taken on Feb.26(limiting mag 19.0), or on the DSS(POSS-II Red) from May.15,1985(limiting mag about 20.5).

Bin Tian’s private observatory follow-up the possible supernova (mag approximately 17.5) on one 300-s image (limiting mag about 19.0) around Mar.01.57425 UT. Using a CCD + Sharpstar AL-130 Refracting telescope D=130-mm @f/6.67.
