Circular_text TITLE: GCN CIRCULAR NUMBER: 12964 SUBJECT: GRB 120219A: Swift detection of a burst DATE: 12/02/19 14:40:43 GMT FROM: David Palmer at LANL C. A. Swenson (PSU), D. N. Burrows (PSU), N. Gehrels (NASA/GSFC), F. E. Marshall (NASA/GSFC), A. Melandri (INAF-OAB), D. M. Palmer (LANL), C. J. Saxton (UCL-MSSL), B. Sbarufatti (INAF-OAB/PSU), G. Tagliaferri (INAF-OAB) and T. N. Ukwatta (MSU) report on behalf of the Swift Team: At 14:30:08 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 120219A (trigger=515375). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 129.793, +51.025 which is RA(J2000) = 08h 39m 10s Dec(J2000) = +51d 01' 29" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). As is usual for an image trigger, there is no obvious variation in the immediately available lightcurve. The XRT began observing the field at 14:32:16.4 UT, 128.3 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 129.79218, 51.03194 which is equivalent to: RA(J2000) = 08h 39m 10.12s Dec(J2000) = +51d 01' 55.0" with an uncertainty of 4.1 arcseconds (radius, 90% containment). This location is 25 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 3.48 x 10^20 cm^-2 (Kalberla et al. 2005). The initial flux in the 2.5 s image was 2.37e-09 erg cm^-2 s^-1 (0.2-10 keV). UVOT took a finding chart exposure of 150 seconds with the White filter starting 139 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 0.03. Burst Advocate for this burst is C. A. Swenson (cswenson AT astro.psu.edu). 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.)

On our first (20s exposure, diagonal polarisation) set we haven't found optical transient within SWIFT XRT error-box. The 5-sigma upper limit has been about 17.0 mag One MASTER Very Wide Field Camera located at Tunka (D=68 mm, 420 square degrees, 11 Mpx) was observed GRB error box with 5 s exposure befoure, during and after GRB Trigger Time without time gap between images. Our unfiltered images are calibrated relative to Tycho stars (V). The magnitude limit of the each emage is 11.5 m at the edge of FOW. We do not detect OT. But we need the duration and beginning time of the GRB. The redaction is continuated. The message may be cited.

Wang, J.S. Deng, C. Wu, X. H. Han on behalf of EAFON report: We began to observe GRB120219A (Swenso et al. GCN 12964 ) with Xinglong TNT telescope at 14:32:15 (UT), 127 sec after the burst. A serveral white and R-band were obtained. After combining 11*300s R-band images, a new marginal source was found within the errorbox of X-ray counterpart ( Swenso et al. GCN 12964). Its coordinates ( RA and Dec ) are 08:39:09.55 51:01:56.5 (J2000) with an uncertainty of about 1 arcsecond. The brightness of the source is estimated to be about 21.5 +/- 0.3 mag relatively to USNO B1.0 R2 mag at the mean time of 37 min after the burst. Further observations and confirmation are encouraged.

Beardmore and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team. Using 1088 s of XRT Photon Counting mode data and 2 UVOT images for GRB 120219A, 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 = 129.79026, +51.03174 which is equivalent to: RA (J2000): 08h 39m 9.66s Dec (J2000): +51d 01' 54.2" with an uncertainty of 1.6 arcsec (radius, 90% confidence).

Sato (ISAS), M. Stamatikos (OSU), C. A. Swenson (PSU), 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 120219A (trigger #515375) (Swenson, et al., GCN Circ. 12964). The BAT ground-calculated position is RA, Dec = 129.862, 51.006 deg, which is RA(J2000) = 08h 39m 26.8s Dec(J2000) = +51d 00' 21.4" with an uncertainty of 2.2 arcmin, (radius, sys+stat, 90% containment). The partial coding was 77%. The mask-weighted light curve shows two slightly overlapping peaks starting at ~T-15 sec, peaking at T+0 and T+70 sec, and returning to baseline at ~T+140 sec. T90 (15-350 keV) is 90.5 +- 10.9 sec (estimated error including systematics). The time-averaged spectrum from T-7.83 to T+90.06 sec is best fit by a power law with an exponential cutoff. This fit gives a photon index -0.60 +- 1.69, and Epeak of 51.6 +- 14.2 keV (chi squared 54.9 for 56 d.o.f.). For this model the total fluence in the 15-150 keV band is 5.4 +- 1.4 x 10^-7 erg/cm2 and the 1-sec peak flux measured from T-2.30 sec in the 15-150 keV band is 0.3 +- 0.1 ph/cm2/sec. A fit to a simple power law gives a photon index of 1.56 +- 0.23 (chi squared 63.9 for 57 d.o.f.). All the quoted errors are at the 90% confidence level.

Swenson (PSU) reports on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 120219A 139 s after the BAT trigger (Swenson et al., GCN Circ. 12964). No optical afterglow consistent with the XRT position (Goad et al., GCN Circ. 12967) is detected in the initial UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf.

Circular_text TITLE: GCN CIRCULAR NUMBER: 12971 SUBJECT: GRB 120219A: Swift-XRT refined Analysis DATE: 12/02/20 07:40:03 GMT FROM: Phil Evans at U of Leicester D.N. Burrows (PSU), O.M. Littlejohns (U. Leicester), J.P. Osborne (U. Leicester), K.L. Page (U. Leicester), G. Stratta (ASDC), P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC), J.A. Kennea (PSU), M.C. Stroh (PSU) and C.A. Swenson report on behalf of the Swift-XRT team: We have analysed 6.3 ks of XRT data for GRB 120219A (Swenson et al. GCN Circ. 12964), from 118 s to 51.3 ks after the BAT trigger. The data comprise 667 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 12967). The light curve can be modelled with an initial power-law decay with an index of alpha=3.25 (+0.11, -0.10), followed by a break at T+444 s to an alpha of 1.64 (+0.15, -0.14). A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 3.25 (+0.16, -0.14). The best-fitting absorption column is 2.25 (+0.26, -0.24) x 10^21 cm^-2, in excess of the Galactic value of 3.5 x 10^20 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 2.11 (+0.14, -0.11) and a best-fitting absorption column consistent with the Galactic value. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.4 x 10^-11 (3.8 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 0 (+3.4, -0) x 10^20 cm^-2 Galactic foreground: 3.5 x 10^20 cm^-2 Excess significance: <1.6 sigma Photon index: 2.11 (+0.14, -0.11) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00515375.

Bellm (Caltech) report: We imaged the location of GRB 120219A (Swenson et al., GCN 12964) with the Keck I telescope (+ LRIS) on 2012-02-20 (UT) between 10:22-10:41 UT. Observations suffered from strong attenuation due to clouds and poor seeing (>2 arcsec). In a stack of our two deepest individual 200 second R-band frames (at 10:27 and 10:32) UT, we detect no source to a limiting magnitude of R > 24.0 mag. The afterglow is also not detected in our g-band or I-band images. If the reported object of Xin et al. (GCN 12966) represents a real source, this apparent fading confirms it as the afterglow of GRB 120219A.
