Circular_text TITLE: GCN CIRCULAR NUMBER: 16477 SUBJECT: GRB 140629A: Swift detection of a burst with an optical counterpart DATE: 14/06/29 14:29:09 GMT FROM: Scott Barthelmy at NASA/GSFC A. Y. Lien (GSFC/UMBC), S. D. Barthelmy (GSFC), M. G. Bernardini (INAF-OAB), P. D'Avanzo (INAF-OAB), J. A. Kennea (PSU) and K. L. Page (U Leicester) report on behalf of the Swift Team: At 14:17:30 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140629A (trigger=602884). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 248.982, +41.890 which is RA(J2000) = 16h 35m 56s Dec(J2000) = +41d 53' 25" with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows an initial rise of the event starting at ~T-5 sec out to ~T+5 sec, at which point there is a gap in the TDRSS light curve so nothing can be said at this time for the light curve past T+5 sec. The peak count rate was ~2000 counts/sec (15-350 keV), at ~0 sec after the trigger. The XRT began observing the field at 14:19:04.5 UT, 94.2 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 248.97675, 41.87702 which is equivalent to: RA(J2000) = 16h 35m 54.42s Dec(J2000) = +41d 52' 37.3" with an uncertainty of 4.0 arcseconds (radius, 90% containment). This location is 48 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. No spectrum from the promptly downlinked event data is yet available to determine the column density. The initial flux in the 2.5 s image was 6.08e-10 erg cm^-2 s^-1 (0.2-10 keV). UVOT took a finding chart exposure of 150 seconds with the White filter starting 101 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at RA(J2000) = 16:35:54.46 = 248.97691 DEC(J2000) = +41:52:36.7 = 41.87685 with a 90%-confidence error radius of about 0.74 arc sec. This position is 0.8 arc sec. from the center of the XRT error circle. The estimated magnitude is 14.81 with a 1-sigma error of about 0.14. No correction has been made for the expected extinction corresponding to E(B-V) of 0.01. Burst Advocate for this burst is A. Y. Lien (yarleen AT gmail.com). 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.)

Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team): Using the data set from T-240 to T+622 sec from recent telemetry downlinks, we report further analysis of BAT GRB 140629A (trigger #602884) (Lien, et al., GCN Circ. 16477). The BAT ground-calculated position is RA, Dec = 249.017, 41.897 deg, which is RA(J2000) = 16h 36m 04.1s Dec(J2000) = +41d 53' 49.6" with an uncertainty of 1.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 41%. The mask-weighted light curve shows several overlapping peaks starting at ~T-8 sec, peaking at ~T+12 sec, and ending at ~T+90 sec. T90 (15-350 keV) is 42.0 +- 14.3 sec (estimated error including systematics). The time-averaged spectrum from T-7.53 to T+56.47 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.86 +- 0.11. The fluence in the 15-150 keV band is 2.4 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+12.47 sec in the 15-150 keV band is 4.2 +- 0.4 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

Lien report on behalf of the Swift-XRT team: We have analysed 10 ks of XRT data for GRB 140629A (Lien et al. GCN Circ. 16477), from 80 s to 34.9 ks after the BAT trigger. The data comprise 136 s in Windowed Timing (WT) mode (the first 10 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. 16479). The late-time light curve (from T0+4.2 ks) can be modelled with a power-law decay with a decay index of alpha=1.37 (+/-0.09). A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 1.82 (+0.17, -0.16). The best-fitting absorption column is 4.5 (+3.8, -3.4) x 10^20 cm^-2, in excess of the Galactic value of 9.3 x 10^19 cm^-2 (Willingale et al. 2013). The PC mode spectrum has a photon index of 1.98 (+/-0.10) and a best-fitting absorption column of 5.2 (+2.2, -2.0) x 10^20 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.3 x 10^-11 (3.7 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 5.2 (+2.2, -2.0) x 10^20 cm^-2 Galactic foreground: 9.3 x 10^19 cm^-2 Excess significance: 3.5 sigma Photon index: 1.98 (+/-0.10) If the light curve continues to decay with a power-law decay index of 1.37, the count rate at T+24 hours will be 7.4 x 10^-3 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 2.4 x 10^-13 (2.8 x 10^-13) erg cm^-2 s^-1.

Rose (Notre Dame) We observed the field of GRB140629A (Lien et al. GCN 16477) with the Vatican Advanced Technology Telescope and VATT4K CCD camera on 2014 June 30.2757 (UT). The afterglow is well-detected in two 300s exposures through a SDSS-r filter. Calibrating from SDSS stars in the field we estimate the afterglow to be r=21.08 +/- 0.03 mag at 16.33 hours after the burst. Combining the brightness reported here and SDSS magnitudes estimated by Malesani et al. (GCN 16485) and Perley et al. (GCN 16491), the optical power law decay index is 1.7 between 7 and 16 hours after the burst.

Mainella (INAF/TNG) report on behalf of the CIBO collaboration: We observed the optical afterglow of GRB 140629A (Lien et al., GCN 16477; Yurkov et al. GCN 16478) on 2014 June 30 with the 3.6m TNG telescope located in the Canary Islands, equipped with the DOLORES operated in both imaging and spectroscopic mode. The observations were carried out under poor weather conditions (clouds and calima). In a 120 s image started at 01:41:38 UT (~11.4 hr after the GRB), the afterglow has a magnitude r = 20.4 +/- 0.1 (AB), calibrated against nearby SDSS stars. We also obtained three optical spectra, each one lasting 1200 s, using the grism LR-B covering the wavelength range 3000 - 8000 AA. The observation started at 02:07:21 UT (~11.8 hr after the GRB). Using a preliminary wavelength calibration, in the co-added spectrum we detect several absorption lines which we interpret as due to Ly-alpha, C II (1334), C IV (1548/1550) at a common redshift of 2.29. Our result is in agreement with the redshift reported by Moskvitin et al. (GCN 16489).

Lien (GSFC/UMBC) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 140629A 101 s after the BAT trigger (Lien et al., GCN Circ. 16477). A fading source consistent with the XRT position (Evans et al. GCN Circ. 16479) is detected in the initial UVOT exposures. The fact that it is not seen in uvm2 or uvw2 filters is consistent with the redshift given by Moskvitin et al., GCN Circ. 16489 and DAvanzo et al., GCN Circ. 16493. The preliminary UVOT position is: RA (J2000) = 16:35:54.42 = 248.97676 (deg.) Dec (J2000) = +41:52:36.8 = 41.87690 (deg.) with an estimated uncertainty of 0.42 arc sec. (radius, 90% confidence). Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf.

Frederiks, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, A. Tsvetkova, A.Lyssenko, and T. Cline on behalf of the Konus-Wind team, report: The long GRB 140629A (Swift-BAT trigger #602884: Lien et al., GCN 16477; Cummings et al., GCN 16481; T0(BAT)=14:17:30 UT) was detected by Konus-Wind in the waiting mode. The light curve shows a double-peaked structure which started ~4 s before the BAT trigger and lasted till ~T0(BAT)+22 s. The K-W light curve of this burst is available at http://www.ioffe.rssi.ru/LEA/GRBs/GRB140629A/ As observed by Konus-Wind, the burst had a fluence of (3.4 0.5)x10^-6 erg/cm2 and a 2.944-s peak energy flux, measured from ~T0(BAT)+13.450 s, of (4.7 0.7)x10^-7 erg/cm2 (both in the 20 - 10000 keV energy range). Modeling the KW 3-channel time-integrated spectrum (from T0(BAT)-4.214 s to T0(BAT)+22.282 s) by a power law with exponential cutoff (CPL) model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) yields alpha = -1.42 0.54, and Ep = 86 17 keV. Modelling the 3-channel spectrum near the peak count rate (from T0(BAT)-13.450 s to T0(BAT)+16.394 s) by the CPL model yields alpha = -1.50 0.23, and Ep = 156 52 keV. Assuming the redshift z=2.275 (Moskvitin et al., GCN 16489; D'Avanzo et al., GCN 16493) and a standard cosmology model with H_0 = 70 km/s/Mpc, Omega_M = 0.27, and Omega_Lambda = 0.73, we estimate the following rest-frame parameters: the isotropic energy release E_iso is ~4.4x10^52 erg, the peak luminosity L_iso is ~2.0x10^52 erg/s, and the rest-frame peak energy of the time-integrated spectrum, Ep,i, is ~283 keV. All the quoted errors are estimated at the 1 sigma confidence level. All the presented results are preliminary.
