Circular_text TITLE: GCN CIRCULAR NUMBER: 11705 SUBJECT: GRB 110213A: Swift detection of a burst with optical afterglow DATE: 11/02/13 05:33:13 GMT FROM: David Palmer at LANL V. D'Elia (ASDC), N. Gehrels (NASA/GSFC), J. M. Gelbord (PSU), S. T. Holland (CRESST/USRA/GSFC), H. A. Krimm (CRESST/GSFC/USRA), C. B. Markwardt (NASA/GSFC), D. M. Palmer (LANL), M. H. Siegel (PSU), E. Sonbas (GSFC/USRA/Adiyaman Univ.), E. Troja (NASA/GSFC/ORAU) and T. N. Ukwatta (MSU) report on behalf of the Swift Team: At 05:17:29 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 110213A (trigger=445414). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 43.004, +49.291 which is RA(J2000) = 02h 52m 01s Dec(J2000) = +49d 17' 29" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a single-peaked structure with a duration of about 10 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger. The XRT began observing the field at 05:19:01.2 UT, 91.7 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 42.9641, +49.2726 which is equivalent to: RA(J2000) = 02h 51m 51.38s Dec(J2000) = +49d 16' 21.3" with an uncertainty of 5.5 arcseconds (radius, 90% containment). This location is 115 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. UVOT took a finding chart exposure of 150 seconds with the White filter starting 100 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at RA(J2000) = 02:51:51.40 = 42.96417 DEC(J2000) = +49:16:23.6 = 49.27321 with a 90%-confidence error radius of about 0.61 arc sec. This position is 2.2 arc sec. from the center of the XRT error circle. The estimated magnitude is 16.31 with a 1-sigma error of about 0.14. No correction has been made for the expected extinction corresponding to E(B-V) of 0.32. Burst Advocate for this burst is V. D'Elia (delia AT asdc.asi.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.)

Cenko (UC Berkeley) reports on behalf of a larger collaboration: We have imaged the error circle of GRB110213A (D'Elia et al., GCN 11705) with the automated Palomar 60 inch telescope. Observations began at 05:19 UT (~ 2 minutes after the burst trigger time) and were taken in the r' filter. We detect a bright source at the location of the UVOT afterglow, with coordinates: 02:51:51.43 +49:16:23.3 Using several USNO-B1 field stars for comparison, we measure a magnitude of R ~ 17.1 at this time. Observations are ongoing.

Schaefer (Louisiana State), E.S. Rykoff (LBNL), report on behalf of the ROTSE collaboration: ROTSE-IIIb, located at McDonald Observatory, Texas, responded to GRB 110213A (Swift trigger 445414). The first image was at 05:17:56.7 UT, 27.1 s after the burst (0.7 s after the GCN notice time). The unfiltered images are calibrated relative to USNO A2.0. We detect a 15.8 magnitude, fading source with coordinates: 02:51:51.11 +49:16:20.57 (J2000), with positional uncertainty of 1' or better start UT mag mlim(of image) ---------------------------------- 05:17:56.7 15.8 17.0 This source is not visible in DSS (second epoch), 2MASS or the MPChecker database. Our light curve shows a beautiful rise starting 100 seconds after the Swift trigger, reaching a peak around 14.5 mag at 200 seconds after the trigger and then starting a fast decline. Continuing observations are in progress.

Cenko (UC Berkeley) report on behalf of a larger collaboration: We have obtained a series of optical spectra of the afterglow of GRB 110213A (D'Elia et al, GCN 11705) with the Boller and Chivens Spectrograph mounted on the 2.3-m Bok telescope. Observations began at 05:53 UT (~ 36 minutes after the Swift trigger time) and cover the wavelength range from ~ 4000-8300 A. We detect a series of strong, narrow absorption features corresponding to Mg II and Fe II at a common redshift of z = 1.46. Without the detection of fine structure lines or a DLA system, we cannot definitively identify this as the redshift of the GRB host galaxy. However, the lack of detection of Lyman alpha absorption down to ~ 4000 A limits the redshift of the host galaxy to z <~ 2.3.

Filippenko, University of California, Berkeley, on behalf of the KAIT GRB team, report: The robotic 0.76-m Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory observed GRB 110213A (D'Elia et al., GCN 11705). The automatic sequence started at 05:18:43 UT, 74 s after the BAT trigger. The BAT location has been monitored in V, I, and clear filters, with varying exposure times. Our image processing pipeline found a new object within the BAT error circle, with the following position: R. A. = 02:51:51.40 DEC. = +49:16:23.2 (J2000), which is consistent with the reported afterglow position by D'Elia et al. (GCN 11705), Cenko (GCN 11706), and Rujopakarn et al. (GCN 11707). The OA has magnitude of 17.0 at t = 74 s, brightened to a peak of 14.6 at t = 300 s, then declined to mag 16.0 at t = 2000 s. The OA then displayed several episodes of re-brightening between t = 2000 s and 2600 s, at which point the observation was stopped due to a physical limit of KAIT.

Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team. Using 2597 s of XRT Photon Counting mode data and 3 UVOT images for GRB 110213A, 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 = 42.96403, +49.27257 which is equivalent to: RA (J2000): 02h 51m 51.37s Dec (J2000): +49d 16' 21.2" 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.

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 the recent telemetry downlink, we report further analysis of BAT GRB 110213A (trigger #445414) (D'Elia, et al., GCN Circ. 11705). The BAT ground-calculated position is RA, Dec = 42.978, 49.278 deg which is RA(J2000) = 02h 51m 54.8s Dec(J2000) = +49d 16' 41.4" with an uncertainty of 1.4 arcmin, (radius, sys+stat, 90% containment). The partial coding was 5%. The masked-tagged light curve shows low-level emission starting at about T-30 s and then a steep rise starting at T-3 s to a peak at T+0.5 s, followed by a slow decline out to about T+30 s. T90 (15-350 keV) is 48.0 +- 16.0 sec (estimated error including systematics). The time-averaged spectrum from T-31.2 to T+32.8 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.83 +- 0.12. The fluence in the 15-150 keV band is 5.9 +- 0.4 x 10-6 erg/cm2. The 1-sec peak photon flux measured from T+8.31 sec in the 15-150 keV band is 1.6 +- 0.6 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

D'Elia (ASDC) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 110213A 100 s after the BAT trigger (D'Elia et al., GCN Circ. 11705). This GRB was reported by many observers. We see an initial peak around T+300s after which the GRB declines in brightness until around T+1500s when a small rebrightening occurs. A tentative redshift was reported by P.A. Milne (GCN Circ. No 11708) of z=1.46, which is consistent with the much fainter magnitudes we find in the uvm2 and uvw2 filters. The refined uvot position (90% confidence limit, 0.5" accuracy) with reference to USNO-B1 is: RA (J2000) = 02h 51m 51.39s DEC (J2000) = 49d 16' 23.54" Preliminary magnitudes and 3-sigma upper limits in the UVOT photometric system (Poole et al. 2008, MNRAS, 383, 627) for the first finding chart (FC) exposures and summed with subsequent exposures up to about 2500s are: Filter T_start(s) T_stop(s) Exp(s) Mag (VEGA) white_FC 100 250 147 16.36 +/- 0.05 u_FC 312 562 246 15.54 +/- 0.04 white 100 2579 517 16.57 +/- 0.01 v 642 2455 227 16.19 +/- 0.04 b 568 2206 178 16.77 +/- 0.03 u 312 2529 448 15.94 +/- 0.02 uvw1 692 2505 198 17.28 +/- 0.08 uvm2 667 2479 218 18.72 +/- 0.20 uvw2 618 2606 238 19.10 +/- 0.18 The values quoted above are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.32 in the direction of the burst (Schlegel et al. 1998).

D'Elia (ASDC) report on behalf of the Swift-XRT team: We have analysed 22 ks of XRT data for GRB 110213A (D'Elia et al. GCN Circ. 11705), from 81 s to 54.5 ks after the BAT trigger. The data comprise 121 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 Osborne et al. (GCN. Circ 11712). The light curve can be modelled with a series of power-law decays. The initial decay index is alpha=5.2 (+0.5, -0.4). At T+141 s the decay flattens to an alpha of -0.22 (+0.10, -0.14). The light curve breaks again at T+1489 s to a decay with alpha=1.10 (+0.07, -0.08), before a final break at T+9954 s s after which the decay index is 2.14 (+0.10, -0.09). A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.11 (+/-0.07). The best-fitting absorption column is 2.81 (+0.24, -0.23) x 10^21 cm^-2, in excess of the Galactic value of 2.2 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 4.1 x 10^-11 (6.8 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 2.81 (+0.24, -0.23) x 10^21 cm^-2 Galactic foreground: 2.2 x 10^21 cm^-2 Excess significance: 20.5 sigma Photon index: 2.11 (+/-0.07) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00445414.

Frederiks, E. Mazets, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report: The long GRB 110213A, (Swift/BAT trigger=445414: D'Elia, et al., GCN 11705; Barthelmy et.al, GCN 11714) triggered Konus-Wind at T0=19048.893s UT (05:17:28.893) The burst light curve consists of a single pulse with a total duration of ~50 s. The emission is seen up to ~2 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB110213_T19048/ As observed by Konus-Wind the burst had a fluence of (1.0 0.15)x10-5 erg/cm2, and a 256-ms peak flux, measured from T0+1.024s, of (1.4 0.2)x10-6 erg/cm2/s (both in the 20 keV - 2 MeV energy range). The time-integrated spectrum of the burst (from T0 to T0+24.832 s) is best fitted in the 20 keV - 2 MeV range by a power law with exponential cutoff model, for which alpha = -1.65 (-0.2, +0.3), and Ep = 91(-26, +31) keV, chi2 = 62.5/61 dof. The spectrum at the maximum count rate (measured from T0 to T0+8.448 s) is well fitted in the 20 keV - 2 MeV range by a power law with exponential cutoff model, for which alpha = -1.53 (-0.21, +0.24), and Ep = 110(-20, +32) keV, chi2 = 52.8/61 dof. This spectrum is nearly well fitted in the 20 keV - 2 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -1.28 (-0.32, +0.44), the high energy photon index beta = -2.4 (-0.7, +0.2), the peak energy Ep = 89(-19, +28) keV, chi2 = 49.1/60 dof. Assuming the Bok telescope redshift z = 1.46 (Milne & Cenko, GCN 11708) and a standard cosmology model with H_0 = 71 km/s/Mpc, Omega_M = 0.27, Omega_Lambda = 0.73, the isotropic energy release E_iso is (5.5 0.08)x10^52 erg, the peak luminosity L_iso_max is (1.9 0.3)x10^52 erg/s, and Ep_rest is 224 74 keV. All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.

Foley (MPE) reports on behalf of the Fermi GBM Team: "At 05:17:11.27 UT on 13 February 2011, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 110213A (trigger 319267033 / 110213220) which was also detected by the Swift/BAT (D'Elia et al. 2011, GCN 11705). The GBM on-ground location is consistent with the Swift position. The angle from the Fermi LAT boresight is 101 degrees. The GBM light curve consists of two main pulses with a duration (T90) of about 33 s (50-300 keV). The time-averaged spectrum from T0-3.072 s to T0+31.745 s is well fit by a power law function with an exponential high-energy cutoff. The power law index is -1.44 (+/- 0.05) and the cutoff energy, parameterized as Epeak, is 98.4 (+8.5/-6.9) keV. The event fluence (10-1000 keV) in this time interval is (1.03 +/- 0.03)E-05 erg/cm^2. The 1.024-sec peak photon flux measured starting from T0+18.17 s in the 10-1000 keV band is 17.7 +/- 0.5 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

D'Elia (ASDC) and P. Kuin (MSSL-UCL) report, on behalf of the Swift team: GRB110213A (D'Elia et al., GCN circ 11705) exhibits an interesting behaviour both in the X-ray and optical bands. After a broad peak and phase of normal decline, the lightcurves show achromatic breaks at about T0+10 ks, after which the slopes in both bands becomes about -2. These data strongly indicate that we are seeing a very early jet break. We encourage observations from ground facilities. The predicted magnitudes for 00:00 UT of 15/2/2011 are R ~ 22.6, v ~ 21.7, b ~ 23.8, u ~ 21.7.

D'Elia et al., GCN 11705) under fair observing conditions. Our narrow-field instruments began observing the location at 05:17:58.2 UTC, 28.7 seconds after the initial BAT trigger. We detect the optical counterpart at the location reported by the Swift UVOT team. The counterpart brightens from below our threshold at around 100 seconds after the BAT trigger. It reaches a peak magnitude of 14.7 at T~300 s. The counterpart then begins a steady decline to magnitude 16.0 at T~2000 s. At that point, the counterpart re-brightens to a plateau at roughly magnitude 15.8 for about an hour before resuming the fading behavior.

We took several series in both epochs in R filter. The optical afterglow (D'Elia et al., GCN 11705, Cenko GCN 11706, Rujopakarn et al., GCN 1707) is clearly visible on single 60 s exposure images on Feb. 13, and afterglow is visible in a stacked image on Feb. 15. During our observations within 2 hours on Feb. 13 (0.2555 - 0.3316 days after burst) the brightness of the afterglow was not changing within error bars of about 0.06m. One can suggest that we observed a plateau phase or a broad peak of the afterglow light curve. The afterglow is still bright (R ~ 20.45) at 2.297 days after burst.
