We observed the INTEGRAL/IBIS GRB 160629A (Gotz et al., GCN 19621) with
the AMI Large Array at 15 GHz on 2016 Jul 01.23, Jul 02.23, Jul 04.19,
and Jul 08.19 (UT) as part of the 4pisky program. We detect a transient
radio source consistent with the SAO RAS location (Sokolov et al., GCN
19623) at 219+/-49 uJy and 128+/-37 uJy in the first two epochs, and
obtain 3sigma upper limits of 135 uJy and 243 uJy in the later two epochs.
We thank the AMI staff for scheduling these observations. The AMI-GRB
database is a log of all GRB follow up observations with the AMI, and is

A.P. Beardmore (U. Leicester), A. Maselli (INAF-IASFPA), A. Melandri

Swift-XRT team:
Swift-XRT has performed follow-up observations of the INTEGRAL-detected
burst GRB 160629A (Gotz et al. GCN Circ. 19621), collecting 2.6 ks of
Photon Counting (PC) mode data between T0+77.1 ks and T0+89.3 ks.
An uncatalogued X-ray source is detected within the 3-sigma INTEGRAL
error region and is believed to be the afterglow. Using 1633 s of PC
mode data and 1 UVOT image, we find an enhanced XRT position (using the
XRT-UVOT alignment and matching UVOT field sources to the USNO-B1
catalogue): RA, Dec = 4.86537, +76.96703 which is equivalent to:
RA (J2000): 00h 19m 27.69s
Dec(J2000): +76d 58' 01.3"
with an uncertainty of 3.4 arcsec (radius, 90% confidence). This
position is 111 arcsec from the INTEGRAL position. We cannot determine
at the present time whether the source is fading.
Since this position is consistent with the one reported for the optical
afterglow (Klotz et al. GCN Circ 19622; Sokolov et al. GCN Circ 19623;
Rebolo et al. GCN Circ. 19638), we propose this source as the X-ray
afterglow of GRB 160629A.

The long GRB 160629A (INTEGRAL detection: Gotz et al., GCN 19621;
Fermi GBM observation: Toelge, GCN 19628)
triggered Konus-Wind at T0=80385.314 s UT (22:19:45.314).
The light curve shows a smooth pulse with a total duration of ~40 s.
The weaker subsequent emission is traceable up to ~T0+70 s.
The emission in the main pulse is seen up to ~4 MeV.
As observed by Konus-Wind, the burst had a fluence
of 1.5(-0.4,+0.6)x10^-5 erg/cm2, and a 64-ms peak flux,
measured from T0+10.560 s, of 1.4(-0.3,+0.3)x10^-6 erg/cm2/s
(both in the 20 keV - 10 MeV energy range).
The time-averaged spectrum (measured from T0 to T0+24.832 s)
is best fit in the 20 keV - 5 MeV range
by the GRB (Band) function with the following model parameters:
the low-energy photon index alpha = -0.79 (-0.17,+0.23),
the high energy photon index beta = -2.92 (-3.68,+0.50),
the peak energy Ep = 227 (-41,+41) keV,
chi2 = 76/76 dof.
Assuming the redshift z=3.332 (Castro-Tirado et al., GCN Circ. 19632)
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 ~3.7x10^53 erg,
the peak luminosity L_iso is ~1.5x10^53 erg/s,
and the rest-frame peak energy of the time-integrated spectrum,
Ep,i, is ~980 keV.

"At 22:19:38.28 UT on 26 June 2016, the Fermi Gamma-Ray Burst Monitor
triggered and located GRB 160629A (trigger 488931582 / 160629930),
which was also detected by the INTEGRAL/IBAS
(Gotz et al. 2016, GCN 19621)
The GBM on-ground location is consistent with the INTEGRAL position.
The GBM light curve consists of a long main peak and a short second peak
after
around 65 seconds.
The duration (T90) is about 66.6 +/- 0.4 s (50-300 keV).
The time-averaged spectrum from T0-4.1 s to T0+70.7 s is
best fit by a power law function with an exponential
high-energy cutoff. The power law index is -1.05 +/- 0.03 and
the cutoff energy, parameterized as Epeak, is 295.50 +/- 19.30 keV
The event fluence (10-1000 keV) in this time interval is
(1.9 +/- 0.1)E-05 erg/cm^2. The 1-sec peak photon flux measured
starting from T0+14.1 s in the 8-1000 keV band

The observations started 21s after the GRB trigger

39 degrees above horizon and weather conditions were good.
We detect a new fading source in the error box given by INTEGRAL

optical flux until R~16.4 at 81s. This image must
be analyzed more carefuly.
Magnitudes were estimated with the nearby USNO-B1 stars
