TITLE: GCN CIRCULAR NUMBER: 16598 SUBJECT: GRB 140716A BAT refined analysis DATE: 14/07/16 22:05:17 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift J. R. Cummings, S. D. Barthelmy (GSFC), W. H.

Stamatikos (OSU/NASA/GSFC), J. Tueller (GSFC), T. N. Ukwatta (GWU) on behalf of the Swift-BAT team: We report further analysis of the ground-detected GRB 140716A (Cummings, GCN # 16596) using 20 seconds of photon-event data that cover the first and third peaks, and BAT survey data covering the entire burst. The best BAT position remains RA, Dec 108.133 -60.150, which is RA (J2000) 07h 12m 31.9s Dec (J2000) -60d 08' 59" with an estimated 90% confidence radius of 1.5 arcmin. The source was 3% coded in BAT. The burst had three peaks with similar maximum flux, the first 2 seconds long, the second 4 seconds long at T+90, and the third about 8 seconds long at T+100. The emission was undetectable between the first and second peaks, while there was a slight overlap between peaks 2 and 3. The total T90 was about 104 +- 2 seconds. At T+112 seconds, Swift executed a preplanned slew, putting the source completely out of the BAT coded field of view, but we can say that there was no bright emission above about 50 keV after this time. The average spectrum from 15 to 150 keV is best fit by a simple power law function with a photon index of 1.61 +- 0.33. The total fluence was (5.9 +- 1.2) x 10^-6 ergs/cm^2. The peak 1-second flux was 5.2 +- 1.5 photons/sec/cm^2 from T+0.2 to T+1.2 seconds. All the quoted errors are at the 90% confidence level. A Swift TOO request has been approved and is being executed with the target number 20390.
