  1. GRB 070201 detected by Konus-Wind, INTEGRAL, Swift, MESSENGER • described as an “extremely intense short hard GRB” (GCN 6088) • t0 = 15:23:10.78 UT • duration ~0.15 seconds, followed by a weaker, softer pulse with duration ~0.08 seconds • fluence = 1.57 x 10-5 ergs/cm2(20 keV – 1 MeV) (GCN 6094) • R.A. = 11.089 deg, Dec = 42.308 deg, error = 0.325 sq. deg center is 1.1 deg from center of M31 (D = 770 kpc) and includes its spiral arms (GCN 6103, 6091) • Eiso ~ 1 x 1045 ergs • more similar to SGR energythan GRB energy FLHO = FLLO = 0.3 Konus-Wind lightcurve Burst F2F Meeting I. Leonor

  2. p = 0.5 (25-ms crosscorrelation) p = 0.9 (100-ms crosscorrelation) Crosscorrelation based triggered search preliminary results(no data quality cuts) Burst F2F Meeting I. Leonor

  3. For circularly polarized, 250-Hz, Q = 8.9 sine-gaussians, taking into account antenna factor, and using V1 calibrations: Assuming M31 location, D = 770 kpc, and merger model: Preliminary limits 25-ms crosscorrelation Burst F2F Meeting I. Leonor
