GCN Circular #16477
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.)

Using 794 s of XRT Photon Counting mode data and 2 UVOT images for GRB 140629A, 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 = 248.97716, +41.87689 which is equivalent to:
```
RA (J2000): 16h 35m 54.52s
Dec (J2000): +41d 52' 36.8"

Following the detection of GRB 140629A by Swift (Lien et al. GCNC 16477), we observed the optical counterpart (Lien et al., GCNC 16477, Yurkov et al. GCNC 16478) with the 6-m BTA (+Scorpio-I) on June 29, starting 4.1 hours after the event. We obtained 43.6 minutes of spectral data in the range 4000-9800A and resolution FWHM = 13A. The optical afterglow spectrum shows prominent absorption lines which we interpret as AlIII, CIV, CII, FeII, MgII, SiIV at the redshift z = 2.275 +/- 0.003. We suggest this to be the redshift to GRB 140629A.

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.

We acquired 10 exposures of 180 seconds each. The optical afterglow (Lien et al., GCN 16477; Yurkov et al. GCN 16478) is well-detected in the stacked image. Comparing to SDSS field stars, we measure a magnitude of:
r = 20.91 +/- 0.03 (t_mid = 0.590 days)

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.

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).

The long GRB 140629A (Swift-BAT trigger #602884: Lien et al., GCN 16477;=20 Cummings et al., GCN 16481; T0(BAT)=3D14:17:30 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 =B1 0.5)x10^-6 erg/cm2 and a 2.944-s peak energy flux, measured from ~T0(BAT)+13.450 s, of (4.7 =B1 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 =3D -1.42 =B1 0.54, and Ep =3D 86 =B1 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 =3D -1.50 =B1 0.23, and Ep =3D 156 =B1 52 keV.
Assuming the redshift z=3D2.275 (Moskvitin et al., GCN 16489; D'Avanzo et al., GCN 16493) and a standard cosmology model with H_0 =3D 70 km/s/Mpc, Omega_M =3D 0.27, and Omega_Lambda =3D 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.

GCN Circular #16498
D. A. Perley (Caltech) and S. B. Cenko (NASA/GSFC) report:
We acquired additional imaging of the afterglow of GRB 140629A (Lien et al., GCN 16477; Yurkov et al. GCN 16478) with the Palomar 60-inch (P60) robotic telescope on UT 2014-07-01 between 04:23 and 04:52, acquiring 9x180s exposures in the r' filter. We measure a magnitude of:
r = 22.92 +/- 0.14 (t_mid = 1.598 days)
This indicates a relatively rapid decay index of alpha=1.87 since our observation the previous night (see also Garnavich and Rose, GCN 16492).

A. Moskvitin (SAO-RAS, N. Arkhyz), R. Burenin (IKI, Moscow), R. Uklein, V. Sokolov, T. Sokolova (SAO-RAS, N. Arkhyz), on behalf of a larger collaboration, report:
We performed the photometrical monitoring of the GRB 140629A OT (Lien et al., GCNC 16477) with two optical telescopes of SAO RAS: the 6-m BTA (V band) and the 1-m Zeiss-1000 (BVRcIc bands) on the night of June, 29/30. Observations started 4.1 hours after the Swift trigger. The optical transient (Lien et al., GCNC 16477; Yurkov et al., GCNC 16478; Bikmaev et al., GCNC 16482; Masi, GCNC 16483; Maehara, GCNC 16484; Malesani et al., GCNC 16485; Sonbas et al., GCNC 16486; and other teams) is clearly detected in every single image.
On the basis of the same star from USNO-B1 as Bikmaev et al. (GCNC 16482) with the coordinates R.A., = 16:35:59.9, Decl.= +41:51:10, J2000 and magnitude R1_mag = 16.49 we made preliminary photometric estimations of the OT Rc images. The results are as follows:

Three MASTER system telescopes located in Blagoveshchensk, Tunka and Kislovodsk have observed GRB140629A (Lien et al., GCN 16477) from 33 seconds till ~9 hours after the trigger. MASTER II robotic telescope (MASTER-Net: http://observ.pereplet.ru) located in Blagoveschensk was pointed to GRB140629A 15 sec after notice time and 33 sec after trigger time at 2014-06-29 14:18:03.188 UT and found OT in SWIFT error-box. MASTER II Tunka was pointed to GRB140629A 78 sec after trigger time at 2014-06-29 14:18:48.102 UT on the evening twilight sky (Sun ~5 d. below horizon) with dark sky observations starting ~ 50 min after trigger time. MASTER II Kislovodsk was pointed to GRB140629A ~3.2 hours after the trigger directly after the Sun set and weather conditions became suitable.
The preliminary light curve is available here: http://master.sai.msu.ru/static/GRB/GRB140629A_slope2.png
The optical transient (Lien et al., GCN 16477; Yurkov et al., GCN 16478; Moskvitin et al., GCN 16489; Bikmaev et al., GCN 16482; Masi, GCN 16483; Maehara, GCN 16484; Malesani et al., GCN 16485; Sonbas et al., GCN 16486 etc.) has a maximum at ~ 150 sec. after the burst, reaching 13.8 mag, after which it shows a power law decay. The power law index (alpha) from 200 to 10000 seconds after the trigger is 1.12 +- 0.1 (F ~ t^-alpha).
There was no polarization more than 3% discovered on afterglow stage.

We observed the Swift GRB 140629A field (Lien et al., GCNC 16477) using 1.04m ST telescope at ARIES Nainital. Observations were started at 17:40:59 UT on 2014-06-29 (approximately 3.4 h after the burst). Several frames with an exposure time of 300 s each in R_c and I_c bands were obtained in good sky conditions.
The optical counterpart of GRB 140629A (Lien et al., GCNC 16477; Yurkov et al., GCNC 16478; Bikmaev et al., GCNC 16482; Masi, GCNC 16483; ) is clearly detected in each individual frames.

A.S. Moskvitin, V.N. Komarova, T.N. Sokolova, V.V. Sokolov (SAO RAS, N. Arkhyz), on behalf of a larger collaboration, report:
We observed the GRB 140629A field (Lien et al., GCNC 16477) with the 1-m SAO RAS telescope Zeiss-1000 on June, 30. Observations started at 21:21:36 and ended at 23:48:49 UT. 22 x 300 sec. images in the Rc filter were obtained under good weather conditions.
Unlike the previous night, the OT is not visible in single images, but is clearly detectable in the stacked image. Based on the same USNO-B1 star (Moskvitin et al., GCNC 16499; Bikmaev et al., GCNC 16482) with R1_mag = 16.49, we measured the OT magnitude as R = 22.1 +/- 0.2 on the phase 1.35 days after the trigger.
