Circular_text TITLE: GCN CIRCULAR NUMBER: 19171 SUBJECT: GRB 160313A: Swift detection of a burst DATE: 16/03/13 02:52:40 GMT FROM: Scott Barthelmy at NASA/GSFC A. D'Ai (INAF-IASFPA), S. D. Barthelmy (GSFC), D. N. Burrows (PSU), A. Y. Lien (GSFC/UMBC), A. Maselli (INAF-IASFPA), L. M. McCauley (PSU), D. M. Palmer (LANL), B. Sbarufatti (INAF-OAB/PSU), M. H. Siegel (PSU) and T. N. Ukwatta (LANL) report on behalf of the Swift Team: At 02:37:15 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 160313A (trigger=678929). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 183.788, +57.293 which is RA(J2000) = 12h 15m 09s Dec(J2000) = +57d 17' 34" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows several peaks with a total duration of about 40 sec. The peak count rate was ~1000 counts/sec (15-350 keV), at ~30 sec after the trigger. The XRT began observing the field at 02:39:48.3 UT, 152.5 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source with an enhanced position: RA, Dec 183.7969, 57.2840 which is equivalent to: RA(J2000) = 12h 15m 11.24s Dec(J2000) = +57d 17' 02.3" with an uncertainty of 2.2 arcseconds (radius, 90% containment). This location is 36 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper. No spectrum from the promptly downlinked event data is yet available to determine the column density. UVOT took a finding chart exposure of 150 seconds with the White filter starting 198 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.01. Burst Advocate for this burst is A. D'Ai (antonino.dai AT ifc.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.)

Moskvitin (SAO RAS, Russia) report on behalf of the larger team. The field of GRB 160313A (D'Ai et al., GCNC #19171) was observed with the SAO RAS Zeiss-1000 telescope. The observations started during the morning twilight, since 10 minutes after the trigger. In combined image of 4 x 60 seconds in the Rc band we did not detect any object within the XRT error circle down to the limiting magnitude R_lim = 18.2. This estimation based on the nearby USNO-B1 stars.

Zach Golkhou (ASU), and Vicki Toy (UMD) report: We observed the field of GRB 160313A (D'Ai, et al., GCN 19171) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astronómico Nacional on Sierra San Pedro Mártir from 2016/03 13.14 to 2016/03 13.22 UTC (0.63 to 2.67 hours after the BAT trigger), obtaining a total of 1.42 hours exposure in the r and i bands and 0.52 hours exposure in the Z, Y, J, and H bands. For a source within the Swift-XRT error circle, in comparison with the SDSS DR9 and 2MASS catalogs, we obtain the following upper limits (3-sigma): r > 23.49 i > 23.21 Z > 22.08 Y > 21.48 J > 20.11 H > 20.60 These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB. Further observations are planned. We thank the staff of the Observatorio Astronómico Nacional in San Pedro Mártir.

Beardmore and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team. Using 722 s of XRT Photon Counting mode data and 2 UVOT images for GRB 160313A, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 183.79649, +57.28347 which is equivalent to: RA (J2000): 12h 15m 11.16s Dec (J2000): +57d 17' 00.5" with an uncertainty of 1.9 arcsec (radius, 90% confidence). This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This circular was automatically generated, and is an official product of the Swift-XRT team.

(CNRS-OMP-IRAP), Boer, M., Laugier, R. (CNRS-ARTEMIS), Gendre B. (UVI - Etelman Obs.) report: We imaged the field of GRB 160313A detected by SWIFT (trigger 678929) with the TAROT robotic telescope (D=25cm) located at the Calern observatory, France. The observations started 122s after the GRB trigger (20s after the notice). The elevation of the field decreased from 64 degrees above horizon and weather conditions were good but images are slightly defocused. The first image is trailed with a duration of 60.0s (see the description in Klotz et al., 2006, A&A 451, L39). We do not detect any OT in the XRT error box published by Goad et al. (GCNC 19174).

Circular_text TITLE: GCN CIRCULAR NUMBER: 19176 SUBJECT: GRB 160313A: Swift-XRT refined Analysis DATE: 16/03/13 12:56:17 GMT FROM: Phil Evans at U of Leicester J.P. Osborne (U. Leicester), K.L. Page (U. Leicester), V. D'Elia (ASDC), A. Maselli (INAF-IASFPA), L.M. McCauley (PSU), J.A. Kennea (PSU), B. Sbarufatti (INAF-OAB/PSU), C. Pagani (U. Leicester) and A. D'Ai report on behalf of the Swift-XRT team: We have analysed 7.1 ks of XRT data for GRB 160313A (D'Ai et al. GCN Circ. 19171), from 138 s to 22.9 ks after the BAT trigger. The data comprise 39 s in Windowed Timing (WT) mode (the first 7 s were taken while Swift was slewing) with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Goad et al. (GCN Circ. 19174). The light curve can be modelled with a power-law decay with a decay index of alpha=3.23 (+0.18, -0.16). A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 1.9 (+/-0.4). The best-fitting absorption column is 1.7 (+1.4, -1.1) x 10^21 cm^-2, in excess of the Galactic value of 1.3 x 10^20 cm^-2 (Willingale et al. 2013). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.8 x 10^-11 (4.8 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 1.7 (+1.4, -1.1) x 10^21 cm^-2 Galactic foreground: 1.3 x 10^20 cm^-2 Excess significance: 2.3 sigma Photon index: 1.9 (+/-0.4) If the light curve continues to decay with a power-law decay index of 3.23, the count rate at T+24 hours will be 1.1 x 10^-8 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 4.0 x 10^-19 (5.0 x 10^-19) erg cm^-2 s^-1.

Inside the XRT error circle (Goad et al., GCN 19174) we find no source down to r'> 21.0 mag in a 6x10s exposure (at 36.5 min, mid time), as calibrated against nearby SDSS stars, in agreement with previous reports (Moskvitin et al.

On our first (30s exposure) and following coadd images we haven't found optical transient within SWIFT error-box (D'Ai et al GCN 19171). The observations took during the morning twilight. We have a 5 good images before they become overexposed. The 5-sigma upper limit has been about 16.5 on first single (30s exposure) image and 17.2 on coadd (300 s exposure) image.

Stamatikos (OSU), T. N. Ukwatta (LANL) (i.e. the Swift-BAT team): Using the data set from T-691 to T+962 sec from the recent telemetry downlink, we report further analysis of BAT GRB 160313A (trigger #678929) (A. D'Ai et al., GCN Circ. 19171). The BAT ground-calculated position is RA, Dec = 183.821, 57.278 deg which is RA(J2000) = 12h 15m 17.0s Dec(J2000) = +57d 16' 40.1" with an uncertainty of 2.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 80%. The mask-weighted light curve shows a complex structure with several overlapping pulses. The structure starts at ~ T-5 s and ends at ~ T+45 s. T90 (15-350 keV) is 42.6 +- 6.4 sec (estimated error including systematics). The time-averaged spectrum from T-5.6 to T+44.7 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.36 +- 0.23. The fluence in the 15-150 keV band is 5.8 +- 0.8 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T+24.79 sec in the 15-150 keV band is 0.4 +- 0.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
