Cline on behalf\nof the Konus-Wind team, report:\n\nThe short hard intense GRB 130310A\n(Fermi-LAT detection: Guiriec et al., GCN 14282;\nFermi-GBM detection: Xiong and Chaplin, GCN 14283\nIPN triangulation: Golenetskii et al., GCN 14284)\ntriggered Konus-Wind at T0=72588.897s UT (20:09:48.897)\n\nThe light curve shows a bright hard FRED-like structure\nwith a total duration of ~3 s.\nThe emission is seen up to 10 MeV.\n\nThe Konus-Wind light curve of this GRB is available at\nhttp://www.ioffe.ru/LEA/GRBs/GRB130310_T72588/\n\nAs observed by Konus-Wind, the burst\nhad a fluence of (3.0 � 0.3)x10-5 erg/cm2,\nand a 16-ms peak flux, measured from T0+0.000s,\nof (3.6 � 0.2)x10-4 erg/cm2/s\n(both in the 20 keV - 10 MeV energy range).\n\nThe time-integrated spectrum (measured from T0 to T0+8.448 s)\nis best fit in the 20 keV - 15 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -1.03 � 0.05,\nthe high energy photon index beta = -1.85 � 0.15,\nthe peak energy Ep = 855 � 270 keV,\nchi2 = 85.8/97 dof.\n\nThe spectrum at the maximum count rate (measured from T0 to T0+0.064 s)\nis best fit in the 20 keV - 15 MeV range\nby the GRB (Band) function with the following model parameters:\nthe low-energy photon index alpha = -0.87 � 0.13,\nthe high energy photon index beta = -1.62 � 0.28,\nthe peak energy Ep = 2600 � 1400 keV,\nchi2 = 27.9/26 dof.\n\nAll the quoted results are preliminary.",
