Circular_text TITLE: GCN CIRCULAR NUMBER: 12834 SUBJECT: GRB 120116A: Swift detection of a burst DATE: 12/01/16 18:17:28 GMT FROM: Scott Barthelmy at NASA/GSFC A. Melandri (INAF-OAB), S. D. Barthelmy (GSFC), A. P. Beardmore (U Leicester), S. Campana (INAF-OAB), P. D'Avanzo (INAF-OAB), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), A. Y. Lien (NASA/GSFC/ORAU), D. M. Palmer (LANL), T. Sakamoto (NASA/UMBC), B. Sbarufatti (INAF-OAB/PSU), M. H. Siegel (PSU), R. L. C. Starling (U Leicester), C. A. Swenson (PSU), T. N. Ukwatta (MSU), C. A. Wolf (PSU) and B.-B. Zhang (PSU) report on behalf of the Swift Team: At 18:06:28 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 120116A (trigger=511866). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 16.248, +33.929, which is RA(J2000) = 01h 05m 00s Dec(J2000) = +33d 55' 44" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows at least two precursor peaks followed by a complex FRED peak with a total duration of at least 50 sec. The peak count rate was ~4000 counts/sec (15-350 keV), at ~1 sec after the trigger. The XRT began observing the field at 18:07:42.5 UT, 74.4 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 16.24183, 33.93034 which is equivalent to: RA(J2000) = 01h 04m 58.04s Dec(J2000) = +33d 55' 49.2" with an uncertainty of 4.0 arcseconds (radius, 90% containment). This location is 19 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. We cannot determine whether the source is fading at the present time. A power-law fit to a spectrum formed from promptly downlinked event data gives a column density consistent with the Galactic value of 4.64 x 10^20 cm^-2 (Kalberla et al. 2005). The initial flux in the 2.5 s image was 6.52e-10 erg cm^-2 s^-1 (0.2-10 keV). UVOT took a finding chart exposure of 150 seconds with the White filter starting 83 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 0.05. Burst Advocate for this burst is A. Melandri (andrea.melandri 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.)

Sakamoto (GSFC/UMBC), 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-61 to T+242 sec from the recent telemetry downlink, we report further analysis of BAT GRB 120116A (trigger #511866) (Melandri, et al., GCN Circ. 12834). The BAT ground-calculated position is RA, Dec = 16.240, 33.927 deg, which is RA(J2000) = 01h 04m 57.7s Dec(J2000) = +33d 55' 36.3" with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 85%. The mask-weighted light curve shows a couple small precursor peaks starting at ~T-30 sec. The main peak has a fast rise starting around T-2 sec, peaking at ~T+0 sec, and a roughly linear decay ending around T+30 sec. T90 (15-350 keV) is 41.0 +- 5.0 sec (estimated error including systematics). The time-averaged spectrum from T-33.44 to T+26.57 sec is best fit by a power law with an exponential cutoff. This fit gives a photon index 1.31 +- 0.41, and Epeak of 19.4 +- 6.3 keV (chi squared 55.4 for 56 d.o.f.). For this model the total fluence in the 15-150 keV band is 2.9 +- 0.1 x 10^-6 erg/cm2 and the 1-sec peak flux measured from T+0.00 sec in the 15-150 keV band is 4.1 +- 0.3 ph/cm2/sec. A fit to a simple power law gives a photon index of 2.70 +- 0.07 (chi squared 101.2 for 57 d.o.f.). 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/511866/BA/

Mikuz on behalf of PIKA observing program at Crni Vrh Observatory. We observed the field of GRB 120116A (GCN 12834) from Crni Vrh Observatory with a 60 cm robotic telescope, R filter and CCD. Twenty consecutive exposures of 60 second duration were taken. First exposure started at 2012-01-16 18:07:47 UT, 79 seconds after the burst (60 seconds after the SWIFT trigger). No optical candidate was detected within the uncertainty radius on single exposures, having R limiting magnitude 20.0 +/-0.2. Also we found no optical candidate on 20 sumed R images with total exposure of 1200 seconds and limiting R band magnitude 22.0 +/-0.2 (all magnitudes calibrated against the nearby USNO B1.0 R2 magnitude stars).

Tanvir (U. Leicester) report for a larger collaboration: "We observed GRB 120116A (Melandri et al. GCN 12834) with Gemini North beginning at Jan 17 04:54, approximately 11 hours after the burst trigger. We obtained optical imaging in iz with GMOS and near-IR imaging in JHK with GNIRS. Within the XRT localization of the source we find a faint object at RA(J2000) 01:04:57.84 DEC(J2000) 33:55:51.1 (error +/- 0.3") with preliminary magnitudes (calibrated against SDSS and 2MASS) of i=24.7 +/- 0.2 z=24.7 +/- 0.3 J> 23.0 (3-sigma) H=22.8 +/- 0.4 K=21.6 +/- 0.3 This object is a plausible counterpart for GRB 120116A. However, at present we cannot assess if the source is fading, as it is significantly fainter than earlier optical limits (Quadri et al. GCN 12836, Sanchez-Ramirez et al. GCN 12837, Vreeswijk et al. GCN 12838, Levan et al. GCN 12841). We further note that the probability of a chance alignment of an object with this magnitude within a 2" error XRT position is non-negligible. We thank the staff of Gemini, in particular Richard McDermid for their assistance in acquiring these data. "

Beardmore and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team. Using 1642 s of XRT Photon Counting mode data and 3 UVOT images for GRB 120116A, 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 = 16.24134, +33.93057 which is equivalent to: RA (J2000): 01h 04m 57.92s Dec (J2000): +33d 55' 50.0" with an uncertainty of 1.7 arcsec (radius, 90% confidence).

Campana (INAF-OAB) and P. D'Avanzo (INAF-OAB) report on behalf of the Swift-XRT team: We have analysed 8.2 ks of XRT data for GRB 120116A (Melandri et al. GCN Circ. 12834), from 64 s to 35.1 ks after the BAT trigger. The data comprise 92 s in Windowed Timing (WT) mode (the first 9 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 12846). The light curve can be modelled with a series of power-law decays. The initial decay index is alpha=3.9 (+0.9, -0.8). Centered at T+114 s there is a small flare. The light curve breaks again at T+205 s to a decay with alpha=0.42 (+0.09, -0.07), before a final break at T+8394 s s after which the decay index is 1.24 (+0.69, -0.24). A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 2.93 (+0.33, -0.28). The best-fitting absorption column is 2.5 (+/-0.6) x 10^21 cm^-2, in excess of the Galactic value of 4.6 x 10^20 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 2.19 (+0.19, -0.18) and a best-fitting absorption column of 1.9 (+/-0.5) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.5 x 10^-11 (5.5 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 1.9 (+/-0.5) x 10^21 cm^-2 Galactic foreground: 4.6 x 10^20 cm^-2 Excess significance: 4.8 sigma Photon index: 2.19 (+0.19, -0.18) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00511866.
