Circular_text TITLE: GCN CIRCULAR NUMBER: 12439 SUBJECT: GRB 111016A: Swift detection of a burst DATE: 11/10/16 19:13:07 GMT FROM: Scott Barthelmy at NASA/GSFC V. Mangano (INAF-IASFPA), S. D. Barthelmy (GSFC), D. N. Burrows (PSU), N. Gehrels (NASA/GSFC), C. Guidorzi (U Ferrara), J. A. Kennea (PSU), D. M. Palmer (LANL), P. Romano (INAF-IASFPA), C. J. Saxton (UCL-MSSL), M. H. Siegel (PSU), M. Stamatikos (OSU/NASA/GSFC) and G. Tagliaferri (INAF-OAB) report on behalf of the Swift Team: At 18:37:04 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 111016A (trigger=505646). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 153.806, +27.476 which is RA(J2000) = 10h 15m 13s Dec(J2000) = +27d 28' 32" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows at least 7 well separated peaks with a total duration of at least 230 sec. The peak count rate was ~1600 counts/sec (15-350 keV), at ~0 sec after the trigger, and another equally bright peak at T+160 sec. And there is a possible peak at T+600 sec. The XRT began observing the field at 18:40:03.2 UT, 180 seconds after the BAT trigger. A bright source was present in the field, at the following location RA,Dec(J2000) = 153.8334, 27.4634, which is equivalent to: RA(J2000) = 10h 15m 20.0s Dec(J2000) = +27d 27' 48.3" with an estimated error of 5 arc-seconds radius (90% confidence). UVOT took a finding chart exposure of 150 seconds with the White filter starting 187 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 0.04. Burst Advocate for this burst is V. Mangano (vanessa 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.)

Burrows (PSU), J.A. Kennea (PSU), G. Cusumano (INAF-IASF PA), M. Perri (ASDC) and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team: The XRT began observing the field of GRB 111016A at 18:40:03.2 UT, 178.7 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 153.8334, +27.4634 which is equivalent to: RA(J2000) = 10h 15m 20.01s Dec(J2000) = +27d 27' 48.2" with an uncertainty of 6.0 arcseconds (radius, 90% containment). This location is 98 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy. The initial flux in the 2.5 s image was 0.00e+00 erg cm^-2 s^-1 (0.2-10 keV).

Osborne and A.P. Beardmore (U. Leicester) report on behalf of the Swift-XRT team. Using 5089 s of XRT Photon Counting mode data and 11 UVOT images for GRB 111016A, 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 = 153.83400, +27.46235 which is equivalent to: RA (J2000): 10h 15m 20.16s Dec (J2000): +27d 27' 44.5" with an uncertainty of 1.5 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.

Circular_text TITLE: GCN CIRCULAR NUMBER: 12442 SUBJECT: GRB 111016A: Swift-XRT refined Analysis DATE: 11/10/17 09:25:16 GMT FROM: Vanessa Mangano at INAF-IASFPA V. Mangano (INAF-IASFPA) reports on behalf of the Swift-XRT team: We have analysed 10 ks of XRT data for GRB 111016A (Mangano et al. GCN Circ. 12439), from 185 s to 23.8 ks after the BAT trigger. The data comprise 693 s in Windowed Timing (WT) mode with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Evans et al. (GCN. Circ 12441). The late-time light curve (from T0+4.1 ks) can be modelled with an initial power-law decay with an index of alpha=3.62 (+0.24, -0.98), followed by a break at T+5533 s to an alpha of 1.06 (+0.15, -0.23). A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 1.800 (+/-0.024). The best-fitting absorption column is 1.85 (+/-0.07) x 10^21 cm^-2, in excess of the Galactic value of 2.5 x 10^20 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 2.23 (+0.09, -0.14) and a best-fitting absorption column of 7.3 (+2.2, -3.3) x 10^20 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.2 x 10^-11 (4.1 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 7.3 (+2.2, -3.3) x 10^20 cm^-2 Galactic foreground: 2.5 x 10^20 cm^-2 Excess significance: 3.6 sigma Photon index: 2.23 (+0.09, -0.14) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00505646.

Aoki, Y. Yatsu, M. Hayashi, K. Kawakami, S. Song, Y. Saito and N. Kawai (Tokyo Tech) report on behalf of the MITSuME collaboration: We observed GRB 111016A (Mangano et al., GCNC 12439) with an optical three color (g, Rc, and Ic) CCD camera attached to the MITSuME 50 cm telescope of Akeno Observatory, Yamanashi, Japan. The follow-up observation was started at 18:52:46, ~15 min after the BAT trigger. We did not find any new point source within the enhanced XRT error circle (Evans et al., GCNC 12441) in all the three bands. Photometric results are listed below.

Cenko (UC Berkeley) reports on behalf of a larger collaboration: We have imaged the field of GRB111016A (Mangano et al., GCN 12439) with the robotic Palomar 60 inch telescope. Observations began at 11:30 UT on 2011 October 17 (~ 16.9 hours after the initial Swift trigger) and were obtained in the Sloan r', i', and z' filters. Inside the revised localization of the X-ray afterglow (Evans et al., GCN 12441) we marginally detect a source in the i' filter with coordinates: RA: 10:15:20.23; Dec: +27:27:44.0 (J2000) Compared with nearby point sources from the Sloan Digital Sky Survey, we measure a magnitude of i' ~ 22.1 +/- 0.3 mag at this time. No significant emission is detected at this location in the r' filter to r' > 21.9 mag. Given the modest significance of the detection in only a single filter, we encourage further observations to confirm if this possible source is indeed the afterglow of GRB111016A.

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-239 to T+963 sec from recent telemetry downlinks, we report further analysis of BAT GRB 111016A (trigger #505646) (Mangano, et al., GCN Circ. 12439). The BAT ground-calculated position is RA, Dec = 153.826, 27.474 deg, which is RA(J2000) = 10h 15m 18.2s Dec(J2000) = +27d 28' 26.7" with an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 64%. The mask-weighted light curve shows a series of slighlty overlapping peaks starting at ~T-5 sec, peaking at T+58, T+118, T+160, T+210, T+255, then returning to baseline, followed by smaller peaks at T+410, T+540, T+600, and possible peaks at T+700 and T+800. The burst location goes out of the BAT FOV at T+960 sec. T90 (15-350 keV) is 550 +- 105 sec (estimated error including systematics). The time-averaged spectrum from T+35.41 to T+614.48 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.95 +- 0.12. The fluence in the 15-150 keV band is 4.0 +- 0.3 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+115.23 sec in the 15-150 keV band is 0.9 +- 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/505646/BA/

Circular_text TITLE: GCN CIRCULAR NUMBER: 12446 SUBJECT: GRB 111016A: Swift/UVOT Detection of a Source DATE: 11/10/17 18:18:13 GMT FROM: Tyler Pritchard at PSU T. A. Pritchard (PSU) and V. Mangano (INAF-IASFPA) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 111016A 188 s after the BAT trigger (Mangano et al., GCN Circ. 12439). No optical afterglow consistent with the Enhanced Swift-XRT position (Evans et al., GCN Circ 12441) is detected in the initial UVOT exposures, however a marginal source is detected in followup observations in the UVOT white filter. This position is consistent with the source observed by Cenko et all (GCN Circ 12444). Preliminary 3-sigma upper limits and magnitudes using the UVOT photometric system (Poole et al. 2008, MNRAS, 383, 627) for the first finding chart (FC) exposure and subsequent exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white_FC 188 337 147 >20.3 u_FC 345 595 246 >19.3 white 188 23781 1926 >21.5 white 27360 45216 4662 21.56 v 4468 16602 1278 >20.5 b 5288 23264 1967 >21.6 u 345 22351 1328 >20.4 w1 724 18207 1095 >20.5 m2 700 17507 1298 >20.8 w2 651 12429 1135 >20.7 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.04 in the direction of the burst (Schlegel et al. 1998).

Circular_text TITLE: GCN CIRCULAR NUMBER: 12447 SUBJECT: GRB 111016A: Gemini Detection of the NIR Counterpart DATE: 11/10/18 03:52:20 GMT FROM: S. Bradley Cenko at Caltech S. B. Cenko (UC Berkeley), A. Cucchiara (UC Santa Cruz), N. R. Tanvir (U. Leicester), A. J. Levan (U. Warwick), A. S. Fruchter (STScI), and E. Berger (Harvard) report on behalf of a larger collaboration: We have imaged the field of GRB111016A (Mangano et al., GCN 12439) with the Near-Infrared Imager and Spectrometer (NIRI) mounted on the 8 m Gemini North telescope. Observations were obtained in the J, H, and K filters beginning at 14:25 UT on 2011 October 17 (~ 19.8 hours after the initial Swift trigger). We detect a faint, unresolved source in all three filters coincident with the optical afterglow candidate from P60 (Cenko et al., GCN 12444) and UVOT (Pritchard et al., GCN 12446). Having established the reality of this object, pre-outburst limits from the Sloan Digital Sky Survey imply some degree of variability and establish it as the optical counterpart of GRB111016A. Using the only two 2MASS sources within the NIRI field of view for calibration, we measure K ~ 20.4 +/- 0.2 (Vega) at this time. Assuming limited evolution from the time of the P60 observations, the i' - K color implies a relatively unusual blue SED (flat spectrum in fnu) when compared with other GRB afterglows at this time, particularly given the presence of a modest host galaxy dust column inferred from the X-ray spectrum (Mangano et al., GCN 12442). We caution however, that the photometric calibration in the NIR remains somewhat uncertain due to the lack of reference sources in the field. We wish to thank the entire Gemini staff for the prompt execution of these observations. Further observations are encouraged.

The observation started at 01:59:08 UT on October 17, 2011, approx. 5.5 hours after the Swift trigger. We report no detection of the optical counterpart on the unfiltered images within the error circle given by SWIFT-XRT (Evans et al., GCN 12441). The upper limit of 19.5 mag in R-band was estimated using nearby sources from GSC2.2 catalogue."
