Circular_text TITLE: GCN CIRCULAR NUMBER: 13867 SUBJECT: GRB 121014A: Swift detection of a burst DATE: 12/10/14 20:19:54 GMT FROM: Scott Barthelmy at NASA/GSFC A. Y. Lien (NASA/GSFC/ORAU), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), N. P. M. Kuin (UCL-MSSL), C. Pagani (U Leicester), K. L. Page (U Leicester), D. M. Palmer (LANL), B. Sbarufatti (INAF-OAB/PSU) and E. Sonbas (NASA/GSFC/Adiyaman Univ.) report on behalf of the Swift Team: At 20:11:56 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 121014A (trigger=535960). Swift did not slew because of sun constraint. The BAT on-board calculated location is RA, Dec 166.631, -29.109, which is RA(J2000) = 11h 06m 31s Dec(J2000) = -29d 06' 31" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows an initial 1-2 sec spike at T0, and then smaller and longer peaks at ~T+20 sec and ~T+50 sec. structure with a duration of about 60 sec. The peak count rate was ~3000 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 05:22 UT on 2012 October 30. There will thus be no XRT or UVOT data for this trigger before this time. Burst Advocate for this burst is A. Y. Lien (yarleen AT gmail.com). 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: 13869 SUBJECT: GRB 121014A: Swift-BAT refined analysis DATE: 12/10/15 10:52:56 GMT FROM: Scott Barthelmy at NASA/GSFC 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), D. M. Palmer (LANL), T. Sakamoto (AGU), G. Sato (ISAS), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-60 to T+222 sec from recent telemetry downlinks, we report further analysis of BAT GRB 121014A (trigger #535960) (Lien, et al., GCN Circ. 13867). The BAT ground-calculated position is RA, Dec = 166.645, -29.105 deg, which is RA(J2000) = 11h 06m 34.7s Dec(J2000) = -29d 06' 18.3" with an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 72%. The mask-weighted light curve shows 3 main peaks starting at ~T-0.2 sec, peaking at ~T+0.4, ~T+19, & ~T+50 sec, resp., and ending at ~T+90 sec. T90 (15-350 keV) is 80.0 +- 22.6 sec (estimated error including systematics). The time-averaged spectrum from T-12.21 to T+67.79 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.91 +- 0.17. The fluence in the 15-150 keV band is 1.1 +- 0.1 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+59.29 sec in the 15-150 keV band is 0.3 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
