Circular_text TITLE: GCN CIRCULAR NUMBER: 15012 SUBJECT: GRB 130719A: Swift detection of a burst DATE: 13/07/19 06:07:14 GMT FROM: David Palmer at LANL F. E. Marshall (NASA/GSFC), J. R. Cummings (NASA/UMBC), V. D'Elia (ASDC), C. Gronwall (PSU), P. T. O'Brien (U Leicester) and D. M. Palmer (LANL) report on behalf of the Swift Team: At 05:47:49 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 130719A (trigger=562625). Swift could not slew to the burst due to a Sun constraint. The BAT on-board calculated location is RA, Dec 89.039, -11.585 which is RA(J2000) = 05h 56m 09s Dec(J2000) = -11d 35' 03" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve is dominated by variation from Vela X-1, which is also in the FOV, so nothing can be stated about the burst light curve for this image trigger at this time. Due to the Sun constraint, XRT and UVOT will not be able to observe the burst location until July 26. Burst Advocate for this burst is F. E. Marshall (marshall AT milkyway.gsfc.nasa.gov). 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: 15016 SUBJECT: GRB 130719A, Swift-BAT refined analysis DATE: 13/07/22 11:24:38 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift M. Stamatikos (OSU), S. D. Barthelmy (GSFC), W. H. Baumgartner (GSFC/UMBC), J. R. Cummings (GSFC/UMBC),E. E. Fenimore (LANL), N. Gehrels (GSFC), H. A. Krimm (GSFC/USRA), A. Y. Lien (NASA/GSFC/ORAU), C. B. Markwardt (GSFC), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), G. Sato (ISAS), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 130719A (trigger #562625) (Marshall, et al., GCN Circ. 15012). The BAT ground-calculated position is RA, Dec = 89.038, -11.591 deg which is RA(J2000) = 05h 56m 09.2s Dec(J2000) = -11d 35' 29.0" with an uncertainty of 1.9 arcmin, (radius, sys+stat, 90% containment). The partial coding was 50%. The mask-weighted light curve shows a single weak approximately FRED peak. T90 (15-350 keV) is 177.7 +- 20.5 sec (estimated error including systematics). The time-averaged spectrum from T+6.2 to T+205.2 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.63 +- 0.17. The fluence in the 15-150 keV band is 2.3 +- 0.2 x 10^-06 erg/cm2. The 1-sec peak photon flux measured from T+82.68 sec in the 15-150 keV band is 0.6 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level. The results of the batgrbproduct analysis are available at http://gcn.gsfc.nasa.gov/notices_s/562625/BA/

Circular_text TITLE: GCN CIRCULAR NUMBER: 15030 SUBJECT: GRB 130719A: Skynet/PROMPT observations DATE: 13/07/25 18:43:14 GMT FROM: Adam S. Trotter at UNC-Chapel Hill/PROMPT/Skynet A. Trotter, D. Reichart, A. LaCluyze, J. Haislip, T. Berger, M. Carroll, H. T. Cromartie, R. Egger, A. Foster, C. Foster, N. Frank, K. Ivarsen, D. James, M. Maples, J. Moore, M. Nysewander, E. Speckhard, P. Taylor, and J. A. Crain report Skynet observed the Swift/BAT localization of GRB 130719A (Marshall et al., GCN 15012, Swift trigger #562625) with four 16" telescopes of the PROMPT array at CTIO, Chile. Starting at 2013-07-19, 19:17 UT and continuing until 09:20 UT (t=3.53-4.84h post-trigger), it took ~28 160-sec exposures in each of the BVRI bands. We did not detect a credible afterglow candidate within the 3 arcmin radius of the Swift/BAT error circle, which was centered on RA 05:56:09.4, Dec -11:35:04. We stacked all the images in each band and obtained 3-sigma limiting magnitudes on any afterglow at t~4.2h: Filter B V R I Mag >21.2 >20.6 >20.7 >20.3 Magnitudes are Vega magnitudes, calibrated to 3 USNO-B1/NOMAD stars in the field, and have not been corrected for the expected line-of-sight Milky Way dust extinction E(B-V)~0.7 (Schlegel et al. 1998). No further Skynet observations are scheduled.
