TITLE: GCN CIRCULAR NUMBER: 26974 SUBJECT: GRB200120A: SRG/ART-XC Upper Limit DATE: 20/02/03 16:06:32 GMT FROM: Sergey Molkov at Space Research Inst., Moscow S.Molkov, A.Lutovinov, M.Pavlinsky, I.Lapshov, A.Tkachenko and A.Semena (IKI RAN) report on behalf of SRG/ART-XC team: The SRG/ART-XC telescope crossed the GBM localization region of GRB200120A (GCN26831) and its IPN triangulation (GCN26856) several times after the event. The first pass was approximately 800 seconds after the event time and covered the sky region between lines defined by two pairs of the RA, DEC (J2000) coordinates: 1st (142.420, -69.397) , (130.997, -70.584); 2nd (147.762, -69.996) , (130.734, -71.192). This region has approximately 60% cross section area with the IPN triangulation. We do not detect with ART-XC any source around the GRB200120A position with the upper limit, averaged over FoV, of ~2e-11 ergs/s/cm2 in the 4-12 keV energy band neither in this pass nor in subsequent ones  followed every 4 hours during next few days.
