Circular_text TITLE: GCN CIRCULAR NUMBER: 11525 SUBJECT: GRB 110106B: Swift detection of a burst DATE: 11/01/06 21:41:40 GMT FROM: Scott Barthelmy at NASA/GSFC B. Sbarufatti (INAF-OAB/IASFPA), S. D. Barthelmy (GSFC), W. H. Baumgartner (GSFC/UMBC), D. N. Burrows (PSU), N. Gehrels (NASA/GSFC), J. M. Gelbord (PSU), C. Gronwall (PSU), C. Guidorzi (U Ferrara), S. T. Holland (CRESST/USRA/GSFC), E. A. Hoversten (PSU), J. A. Kennea (PSU), H. A. Krimm (CRESST/GSFC/USRA), V. Mangano (INAF-IASFPA), C. B. Markwardt (NASA/GSFC), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL), T. Sakamoto (NASA/UMBC), C. J. Saxton (UCL-MSSL), M. Stamatikos (OSU/NASA/GSFC), E. Troja (NASA/GSFC/ORAU) and T. N. Ukwatta (MSU) report on behalf of the Swift Team: At 21:26:17 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 110106B (trigger=441676). There was a 3.8 minute delayed slew. The BAT on-board calculated location is RA, Dec 134.196, +46.998 which is RA(J2000) = 08h 56m 47s Dec(J2000) = +46d 59' 52" 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 30 sec. The peak count rate was ~1200 counts/sec (15-350 keV), at ~3 sec after the trigger. The XRT began observing the field at 21:31:44.2 UT, 327.2 seconds after the BAT trigger. Using promptly downlinked data we find an uncatalogued X-ray source located at RA, Dec 134.15458, 47.00194 which is equivalent to: RA(J2000) = 08h 56m 37.10s Dec(J2000) = +47d 00' 07.0" with an uncertainty of 3.8 arcseconds (radius, 90% containment). This location is 102 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 2.37 x 10^20 cm^-2 (Kalberla et al. 2005). UVOT took a finding chart exposure of 150 seconds with the White filter starting 332 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 none of the XRT error circle. 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 0.03. Burst Advocate for this burst is B. Sbarufatti (boris.sbarufatti 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.)

Goad and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team. Using 2412 s of XRT Photon Counting mode data and 2 UVOT images for GRB 110106B, 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 = 134.15423, +47.00272 which is equivalent to: RA (J2000): 08h 56m 37.02s Dec (J2000): +47d 00' 09.8" with an uncertainty of 1.8 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.

Sbarufatti (INAF-OAB/IASFPA), M. Stamatikos (OSU), J. Tueller (GSFC), (i.e. the Swift-BAT team): Using the data set from T-61 to T+243 sec from the recent telemetry downlink, we report further analysis of BAT GRB 110106B (trigger #441676) (Sbarufatti, et al., GCN Circ. 11525). The BAT ground-calculated position is RA, Dec = 134.155, 47.005 deg, which is RA(J2000) = 08h 56m 37.3s Dec(J2000) = +47d 00' 17.5" with an uncertainty of 1.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 37%. The mask-weighted light curve shows 3 main overlapping peaks starting at ~T-6 sec and ending at ~T+23 sec. T90 (15-350 keV) is 24.8 +- 4.8 sec (estimated error including systematics). The time-averaged spectrum from T-10.8 to T+23.5 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.76 +- 0.11. The fluence in the 15-150 keV band is 2.0 +- 0.1 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+4.87 sec in the 15-150 keV band is 2.1 +- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

Circular_text TITLE: GCN CIRCULAR NUMBER: 11534 SUBJECT: GRB 110106B: WHT candidate afterglow DATE: 11/01/07 02:34:14 GMT FROM: Andrew Levan at U.of Leicester A.J. Levan (U. Warwick), N.R. Tanvir, K. Wiersema (U. Leicester), L. Coccato (ESO) report for a larger collaboration: We observed the location of GRB 110106B (Sbarufatti et al. GCN 11525) with the William Herschel Telescope and ACAM. Observations were obtained in the i-band, and began at 7 Jan, 00:41 UT, approximately 3 hours after the burst. Within the refined XRT localization (Beardmore et al. GCN 11532) we find a source at RA(J2000) 08:56:37.02 DEC(J2000) 47:00:09.8 with an uncertainty of ~0.5" in each axis. The source appears to be extended, but may include a point source contribution on top of the extended emission. Photometry of the object suggests i~22.5. This is marginally brighter than the limit of SDSS observations of the region, and suggests some afterglow contribution to the observed flux at this time. Further observations are encouraged."

Berger (Harvard), A.J. Levan (U. Warwick), R. Chornock (Harvard), and N.R. Tanvir (U. Leicester) report: "In addition to the spectroscopic observations reported in GCN #11538 we also obtained i-band imaging of the afterglow candidate of GRB 110106B found with the WHT (GCN #11534) with Gemini-N / GMOS. A total of 900 sec were obtained on source at a mean epoch of 2011 Jan 7.347 UT (10.89 hours after the burst and 7.64 hours after the WHT observation). Digital image subtraction of the Gemini and WHT observations reveals a fading source located at (J2000): RA = 08:56:37.267 DEC = +47:00:10.49 with an uncertainty of about 0.2" in each coordinate. This position is about 1.5" due east of the galaxy noted in GCN #11534, whose redshift is 0.618 (GCN #11538). At this redshift the corresponding projected offset is about 10 kpc. We note that emission is still detected at the position of the afterglow, indicating that an association with an underlying host unrelated to the nearby galaxy may still be possible."

Circular_text TITLE: GCN CIRCULAR NUMBER: 11541 SUBJECT: GRB 110106B: Swift-XRT refined Analysis DATE: 11/01/07 15:12:25 GMT FROM: Boris Sbarufatti at INAF-OAB/IASFPA B. Sbarufatti (INAF-OAB/IASFPA) reports on behalf of the Swift-XRT team: We have analysed 6.2 ks of XRT data for GRB 110106B (Sbarufatti et al. GCN Circ. 11525), from 339 s to 30.3 ks after the BAT trigger. The data comprise 24 s in Windowed Timing (WT) mode with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Beardmore et al. (GCN. Circ 11532). The light curve can be modelled with a series of power-law decays. The light curve initially rises, with an index alpha=-1.5 (+0.0, -1.3). At T+470 s it breaks to an alpha of 0.64 (+/-0.07) before breaking again at T+14354 s to a final decay with index alpha=1.6 (+1.0, -0.5). A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.20 (+/-0.16). The best-fitting absorption column is 2.08 (+0.44, -0.22) x 10^21 cm^-2, in excess of the Galactic value of 2.4 x 10^20 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.8 x 10^-11 (6.1 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 2.08 (+0.44, -0.22) x 10^21 cm^-2 Galactic foreground: 2.4 x 10^20 cm^-2 Excess significance: 15.4 sigma Photon index: 2.20 (+/-0.16) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00441676.

Bhat (UAH) reports on behalf of the Fermi GBM Team: "At 21:26:16.08 UT on 06 January 2011, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 110106B (trigger 316041978 / 110106893). which was also detected by the Swift/BAT (Sbarufatti et al. 2011, GCN 11525) The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight was 103 degrees. This burst was also independently detected by INTEGRAL SPI-ACS. The GBM light curve consists of several pulses with a duration (T90) of about 35.5 s (50-300 keV). The time-averaged spectrum from T0-26.6 s to T0+25.6 s is adequately fit by a simple power law function with index -1.61 +/- 0.04 (C-stat 849 for 242 d.o.f.). The event fluence (10-1000 keV) in this time interval is (5.90 +/- 0.44)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+16.13 s in the 10-1000 keV band is 2.77 +/- 0.27 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
