Cline on behalf of the Konus-Wind team, report:\n\nThe ultra-long GRB 200612A\n(Swift-BAT detection Sonbas et al., GCN 27915;\nMASTER OT detection: Lipunov et al., GCN 27917)\nwas detected by Konus-Wind in the waiting mode.\n\nThe burst light curve shows four emission episodes\nin the interval from ~T0(BAT) s to ~T0(BAT)+1020 s.\n\nThe K-W light curve of this burst is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB200612A/\n\nAs observed by Konus-Wind, the burst had a fluence of\n4.08(-0.34,+1.04)x10^-5 erg/cm2 and a 2.944-s peak flux,\nmeasured from ~T0(BAT)+478.8 s, of 2.75(-0.62,+0.85)x10^-7 erg/cm2/s\n(both in the 20 - 1500 keV energy band).\n\nThe K-W 3-channel time-integrated spectrum\n(from ~T0(BAT) s to ~T0(BAT)+1020 s)\nis well described by a cutoff power-law model\nwith alpha = -1.0(-0.2,+0.3) and Ep= 253(-65,+95) keV.\n\nAll the quoted errors are estimated at the 1 sigma confidence level.\nAll the presented results are preliminary.",
