Circular_text TITLE: GCN CIRCULAR NUMBER: 19436 SUBJECT: GRB 160519A: Swift detection of a burst DATE: 16/05/19 00:29:48 GMT FROM: Scott Barthelmy at NASA/GSFC P. D'Avanzo (INAF-OAB), S. D. Barthelmy (GSFC) and J. A. Kennea (PSU) report on behalf of the Swift Team: At 00:17:33 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 160519A (trigger=686818). Swift did not slew due to Sun constraint. The BAT on-board calculated location is RA, Dec 71.113, +31.197, which is RA(J2000) = 04h 44m 27s Dec(J2000) = +31d 11' 48" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single, possibly multiple, peaks with a duration of about 6 sec. The peak count rate was ~1500 counts/sec (15-350 keV), at ~0 sec after the trigger. Due to a Sun observing constraint, Swift cannot slew to the BAT position until 11:24 UT on 2016 July 22. There will thus be no XRT or UVOT data for this trigger before this time. Burst Advocate for this burst is P. D'Avanzo (paolo.davanzo AT brera.inaf.it). Please contact the BA by email if you require additional information regarding Swift followup of this burst. In extremely urgent cases, after trying the Burst Advocate, you can contact the Swift PI by phone (see Swift TOO web site for information: http://www.swift.psu.edu/too.html.)

Circular_text TITLE: GCN CIRCULAR NUMBER: 19439 SUBJECT: GRB 160519A: Fermi GBM detection DATE: 16/05/19 18:27:43 GMT FROM: Peter Veres at UAH P Veres (UAH) and C Meegan (UAH) report on behalf of the Fermi GBM Team: "At 2016-05-19 00:17:33.55 UT on 19 May 2016, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 160519A (trigger 485309857 / 160519012), which was also detected by Swift (D'Avanzo et al., GCN 19436). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight to the best location is 52 degrees. The GBM light curve consists of multiple, weak emission episodes with a duration (T90) of about 97 s (50-300 keV). The time-averaged spectrum from T0-3.6 s to T0+40.4 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.97 +/- 0.25 and the cutoff energy, parameterized as Epeak, is 61.7 +/- 7.3 keV. The event fluence (10-1000 keV) in this time interval is (1.4 +/- 0.1)E-6 erg/cm^2. The 1-sec peak photon flux measured starting from T0-0.2 s in the 10-1000 keV band is 3.3 +/- 0.2 ph/s/cm^2. A Band function fits the spectrum equally well with Epeak = 51 +/- 11 keV, alpha = -0.67 +/- 0.51 and beta = -2.51 +/- 0.36. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

Circular_text TITLE: GCN CIRCULAR NUMBER: 19441 SUBJECT: GRB 160519A: Swift-BAT refined analysis DATE: 16/05/20 22:51:21 GMT FROM: Amy Lien at GSFC M. Stamatikos (OSU), S. D. Barthelmy (GSFC), J. R. Cummings (GSFC/UMBC), P. D'Avanzo (INAF-OAB), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), A. Y. Lien (GSFC/UMBC), C. B. Markwardt (GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team): Using the data set from T-240 to T+962 sec from the recent telemetry downlink, we report further analysis of BAT GRB 160519A (trigger #686818) (D'Avanzo, et al., GCN Circ. 19436). The BAT ground-calculated position is RA, Dec = 71.122, 31.246 deg which is RA(J2000) = 04h 44m 29.2s Dec(J2000) = +31d 14' 46.1" with an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 19%. The mask-weighted light curve shows a single-pulse structure that starts at ~ T-1 s, peaks at ~T0, and ends at ~T+3 s. There are some weak emissions extend till ~T+40 s. T90 (15-350 keV) is 35.57 +- 6.11 sec (estimated error including systematics). The time-averaged spectrum from T-0.99 to T+41.12 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.95 +- 0.25. The fluence in the 15-150 keV band is 1.2 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T-0.16 sec in the 15-150 keV band is 2.4 +- 0.5 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

Circular_text TITLE: GCN CIRCULAR NUMBER: 19533 SUBJECT: GRB 160519A: 15 GHz upper limits from AMI DATE: 16/06/14 16:18:09 GMT FROM: Kunal Mooley at Oxford U K. P. Mooley, T. D. Staley, R. P. Fender (Oxford), G. E. Anderson (Curtin), T. Cantwell (Manchester), C. Rumsey, D. Titterington, S. H. Carey, J. Hickish, Y. C. Perrott, N. Razavi-Ghods, P. Scott (Cambridge), K. Grainge, A. Scaife (Manchester) The AMI Large Array robotically triggered on the Swift alert for GRB 160519A (D'Avanzo et al., GCN 19436) as part of the 4pisky program, and subsequent follow up observations were obtained up to 10 days post-burst. Our observations at 15 GHz on 2016 May 19.35, May 20.50, May 22.61, May 26.50, and May 29.49 (UT) do not reveal any variable radio source within the BAT error circle (Stamatikos et al., GCN 19441), with 3sigma upper limits of 202 uJy, 72 uJy, 84 uJy, 87 uJy, and 87 uJy respectively. We thank the AMI staff for scheduling these observations. The AMI-GRB database is a log of all GRB follow up observations with the AMI, and is available at http://4pisky.org/ami-grb/.
