Circular_text TITLE: GCN CIRCULAR NUMBER: 12810 SUBJECT: GRB 120106A: Swift detection of a burst DATE: 12/01/06 14:26:13 GMT FROM: Scott Barthelmy at NASA/GSFC S. Immler (CRESST/GSFC/UMD), S. D. Barthelmy (GSFC), A. P. Beardmore (U Leicester), P. A. Evans (U Leicester), N. Gehrels (NASA/GSFC), S. T. Holland (CRESST/USRA/GSFC), H. A. Krimm (CRESST/GSFC/USRA), A. Y. Lien (NASA/GSFC/ORAU), O.

Sbarufatti (INAF-OAB/PSU), M. H. Siegel (PSU), R. L. C. Starling (U Leicester), T. N. Ukwatta (MSU) and B.-B. Zhang (PSU) report on behalf of the Swift Team: At 14:16:24 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 120106A (trigger=511235). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 66.129, +64.028, which is RA(J2000) = 04h 24m 31s Dec(J2000) = +64d 01' 42" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve show several overlapping peaks starting ~T-8 sec with a total duration of about 20 sec. The peak count rate was ~2400 counts/sec (15-350 keV), at ~1 sec after the trigger. The XRT began observing the field at 14:17:39.0 UT, 74.9 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 66.11105, 64.03810 which is equivalent to: RA(J2000) = 04h 24m 26.65s Dec(J2000) = +64d 02' 17.2" with an uncertainty of 3.9 arcseconds (radius, 90% containment). This location is 46 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 in excess of the Galactic value (2.65 x 10^21 cm^-2, Kalberla et al. 2005), with an excess column of 4.8 (+4.97/-3.87) x 10^21 cm^-2 (90% confidence). The initial flux in the 2.5 s image was 1.88e-09 erg cm^-2 s^-1 (0.2-10 keV). UVOT took a finding chart exposure of 150 seconds with the White filter starting 84 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. Data from the list of sources generated on-board are not available at this time. No correction has been made for the expected extinction corresponding to E(B-V) of 1.19. Burst Advocate for this burst is S. Immler (stefan.immler AT 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.)

Osborne and A.P. Beardmore (U. Leicester) report on behalf of the Swift-XRT team. Using 3180 s of XRT Photon Counting mode data and 6 UVOT images for GRB 120106A, 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 = 66.10754, +64.03837 which is equivalent to: RA (J2000): 04h 24m 25.81s Dec (J2000): +64d 02' 18.1" with an uncertainty of 1.4 arcsec (radius, 90% confidence).

Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-240 to T+962 sec from recent telemetry downlinks, we report further analysis of BAT GRB 120106A (trigger #511235) (Immler, et al., GCN Circ. 12810). The BAT ground-calculated position is RA, Dec = 66.129, 64.050 deg, which is RA(J2000) = 04h 24m 30.9s Dec(J2000) = +64d 03' 00.0" with an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment). The partial coding was 75%. The mask-weighted light curve shows the first peak starting at ~T-7 sec, peaking at ~T+1 sec, and ending at ~T+13 sec. There is a second, weaker peak starting at ~T+50 sec and ending at ~T+65 (possibly T+85) sec. T90 (15-350 keV) is 61.6 +- 4.1 sec (estimated error including systematics). The time-averaged spectrum from T-6.24 to T+60.24 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.53 +- 0.17. The fluence in the 15-150 keV band is 9.7 +- 1.1 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T+0.46 sec in the 15-150 keV band is 1.5 +- 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/511235/BA/

D'Elia (ASDC), V. Mangano (INAF-IASFPA), J.A. Kennea (PSU), M.C. Stroh (PSU), D.N. Burrows (PSU), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester), C. Pagani (U. Leicester) and S. Immler report on behalf of the Swift-XRT team: We have analysed 12 ks of XRT data for GRB 120106A (Immler et al. GCN Circ. 12810), from 64 s to 29.5 ks after the BAT trigger. The data comprise 273 s in Windowed Timing (WT) mode (the first 8 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 Evans et al. (GCN. Circ 12813). The light curve can be modelled with an initial power-law decay with an index of alpha=4.3 (+/-0.3), followed by a break at T+152 s to an alpha of 0.91 (+0.05, -0.04). A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.15 (+0.12, -0.15). The best-fitting absorption column is 7.6 (+6.8, -0.7) x 10^21 cm^-2, consistent with the Galactic value of 7.0 x 10^21 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 4.8 x 10^-11 (1.0 x 10^-10) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 7.6 (+6.8, -0.7) x 10^21 cm^-2 Galactic foreground: 7.0 x 10^21 cm^-2 Excess significance: <1.6 sigma Photon index: 2.15 (+0.12, -0.15) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00511235.
