A.Zyatkov (MephI, Moscow, Russia) report:\n\n\nThe very bright GRB 090926A (FERMI-GBM trigger 275631628 / 090926181;\nBissaldi, GCN 9933) is detected by RT-2 Experiment onboard CORONAS-PHOTON\nsatellite at T0 = 04h 20m 27s (UT). The satellite was in LIGHT mode (pointing\ntowards the SUN) for a short duration at a high latitude in its orbit. During\nthis time, the GOOD time (away from the polar and SAA regions) observation was\nfor 348 sec starting at 04h 16m 55sec (UT) and ending at 04h 22m 43sec (UT).\n\nThe burst light curve consists of multiple peaks of total duration of ~ 17\nsec, followed by a weak tail ending at ~ T0+30 sec. The strongest peak count\nrate is ~ 1200 cts/sec.\n\nThis burst is also independently detected by KONUS-RF, another instrument\nonboard CORONAS-PHOTON satellite (Golenetskii et al., 2009, GCN 9959).\n\nBoth RT-2/S and RT-2/G detectors have registered the burst profile of this\nbright GRB in the energy band of 15 � ~1000 keV with strongest emission in the\nenergy band of 60 � 215 keV.\n \nThe light curve is available at the web-site:\nhttp://csp.res.in/rt2_files/grb090926-lc.html",
