• GCN Circular #5244
  H. A. Krimm (GSFC/USRA), S. D. Barthelmy (GSFC), N. Gehrels (NASA/GSFC), C. Gronwall (PSU), J. A. Kennea (PSU), V. Mangano (INAF-IASFPA), K. M. McLean (LANL/UTD) and M. Stamatikos (NASA/ORAU) report on behalf of the Swift Team:
  At 23:32:44 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060607B (trigger=213934). The BAT on-board calculated location is RA,Dec 42.033, +14.736 {02h 48m 08s, +14d 44' 09"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a duration of about 25 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~0 sec after the trigger. Swift did not slew to this burst due to the Sun constraint.
  Since this burst is only 33 degrees from the Sun, it will not be observable by the Swift narrow field instruments until June 24.
• GCN Circular #5246

Markwardt (GSFC/UMD), D. Palmer (LANL), A. Parsons (GSFC), T. Sakamoto (GSFC/ORAU), G. Sato (GSFC/JSPS/USRA), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC), on behalf of the Swift-BAT team:
  Using the data set from T-239.4 to T+250 sec from the recent telemetry downlink, we report further analysis of BAT GRB 060607 (trigger #213934) (Krimm, et al., GCN 5244). The BAT ground-calculated position is (RA,Dec) = 42.048, 14.749 deg {2h 48m 11.6s, 14d 44' 57.1"} (J2000) +- 1.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 35%.
  The mask-weighted light curve shows a double-peaked structure with peaks at T+1 sec and T+9 sec. There is low-level emission out to T+30 sec. T90 (15-350 keV) is 31 +- 5 sec (estimated error including systematics).
  The time-averaged spectrum from T-0.8 to T+37.1 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.63 +- 0.12. The fluence in the 15-150 keV band is 1.7 +- 0.1 x 10^-06 erg/cm2. The 1-sec peak photon flux measured from T+8.64 sec in the 15-150 keV band is 1.5 +- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

  "The Watcher 0.4m telescope, located in Boyden Observatory, South Africa, observed the SWIFT error box for GRB 060607B (Krimm et al. GCN 5244, Barbier et al GCN 5246).
  The observation started at 03:27:40 UT (~4h after the GRB). A limiting R-band calibrated, unfiltered magnitude of 18.5 is derived for any optical afteglow emission arising from this particular GRB.
