GCN Circular #19697
M. H. Siegel (PSU), J. A. Kennea (PSU), A. Y. Lien (GSFC/UMBC), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL) and B. Sbarufatti (INAF-OAB/PSU) report on behalf of the Swift Team:
At 02:19:15 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 160714A (trigger=704310). Swift did not slew immediately due to an observational constraint. The BAT on-board calculated location is RA, Dec 234.461, +63.831 which is
```
   RA(J2000) = 15h 37m 51s
   Dec(J2000) = +63d 49' 53"
```
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 0.5 sec. The peak count rate was ~2000 counts/sec (15-350 keV), at ~0.3 sec after the trigger.
Due to an observing constraint, Swift will not slew until T0+26.0 minutes. There will be no XRT or UVOT data until this time.
Burst Advocate for this burst is M. H. Siegel (siegel AT swift.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.)

M. Perri (ASDC), G. Tagliaferri (INAF-OAB), P.A. Evans (U. Leicester), J.P. Osborne (U. Leicester), D.N. Burrows (PSU) and J.A. Kennea (PSU) report on behalf of the Swift-XRT team:
The XRT began observing the field of GRB 160714A at 02:47:12.7 UT, 1677.2 seconds after the BAT trigger. No source was detected in 1.0 ks of promptly downlinked data, which covered 88% of the BAT error circle. We are waiting for the full dataset to detect and localise the XRT counterpart.

A. de Ugarte Postigo (IAA-CSIC, DARK/NBI), A. Sota (IAA-CSIC) report on behalf of a larger collaboration:
We have observed the field of GRB 160714A (Siegel et al. GCN 19697) with the 1.5m OSN telescope, in Granada (Spain). Observations started at 2:33 UT (14 min after the GRB onset) and consisted of 3x180s + 4x300s I-band images. Each of the individual images cover the complete BAT error circle. In a preliminary analysis we detect no new source within the BAT error box down to a 3-sigma limit of I(AB) > 20.5 mag in the first image, and down to I(AB) > 21.5 mag in the combined image (mean time 2:48 UT, 29 minutes after the burst), as compared to SDSS data.

Using the data set from T-239 to T+963 sec from the recent telemetry downlink, we report further analysis of BAT GRB 160714A (trigger #704310) (Siegel, et al., GCN Circ. 19697). The BAT ground-calculated position is RA, Dec = 234.490, 63.809 deg which is
```
   RA(J2000)  =  15h 37m 57.7s
   Dec(J2000) = +63d 48' 32.1"
```
with an uncertainty of 2.7 arcmin, (radius, sys+stat, 90% containment). The partial coding was 35%.
The mask-weighted light curve shows a double-peak structure starting at T0, peaking at T+0.05 sec and T+0.2 sec and ending at T+0.3 sec. T90 (15-350 keV) is 0.35 +- 0.11 sec (estimated error including systematics).
The time-averaged spectrum from T+0.02 to T+0.40 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.38 +- 0.37. The fluence in the 15-150 keV band is 6.9 +- 1.6 x 10^-8 erg/cm2. The 1-sec peak photon flux measured from T-0.29 sec in the 15-150 keV band is 1.1 +- 0.3 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
The results of the batgrbproduct analysis are available at http://gcn.gsfc.nasa.gov/notices_s/704310/BA/

Hoi-Fung Yu (MPE) and Charles A. Meegan (USRA) report on behalf of the Fermi GBM Team:
"At 02:19:15.62 UT on 14 July 2016, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 160714A (trigger 490155559/160714097), which was also detected by the Swift/BAT (Siegel et al. 2016, GCN 19697) The GBM on-ground location is consistent with the Swift position.
The angle from the Fermi LAT boresight at the GBM trigger time is 51 degrees.
The GBM light curve shows a short pulse with sub-structures with a duration (T90) of about 0.32 s (50-300 keV). The time-averaged spectrum from T0-0.064 s to T0+0.192 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.5 +/- 0.4 and the cutoff energy, parameterized as Epeak, is 200 +/- 55 keV.
The event fluence (10-1000 keV) in this time interval is (1.6 +/- 0.3)E-07 erg/cm^2. The 64-ms peak photon flux measured starting from T0+0.128 s in the 10-1000 keV band is 6 +/- 1 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

We have analysed 6.2 ks of Photon Counting (PC) mode XRT data for the Swift/BAT-detected burst GRB 160714A (Palmer et al. GCN Circ. 19705), collected between T0+1.7 ks and T0+43.3 ks.
Three uncatalogued X-ray sources have been detected within 296 arcsec of the Swift/BAT position, however none of them is above the RASS limit or shows definitive signs of fading. Therefore, at the present time we cannot identify which, if any, is the afterglow. Details of these sources are given below:
Source 1:

  RA (J2000.0):  234.3249  =  15:37:17.98

  Error: 4.3 arcsec (radius, 90% conf.)
  Count-rate: (5.8 +/- 1.2)e-3 ct s^-1	 
  Distance: 254 arcsec from Swift/BAT position.
  Flux: (1.78 +/- 0.37)e-13 erg cm^-2 s^-1 (observed, 0.3-10 keV)

  RA (J2000.0):  234.4312  =  15:37:43.50
  Dec (J2000.0): +63.8530  =  +63:51:10.9
  Error: 7.1 arcsec (radius, 90% conf.)
  Count-rate: (1.70 +/- 0.76)e-3 ct s^-1   
  Distance: 92 arcsec from Swift/BAT position.
  Flux: (7.0 +/- 3.2)e-14 erg cm^-2 s^-1 (observed, 0.3-10 keV)
```
Eight uncatalogued sources were also detected too far from the GRB position to be likely afterglow candidates.
The results of the XRT-team automatic analysis of the XRT observations, including a position-specific upper limit calculator, are available at http://www.swift.ac.uk/ToO_GRBs/00704310.

Klotz A., Turpin D., Atteia J.L. (CNRS-OMP-IRAP), Boer, M., Laugier, R. (CNRS-ARTEMIS), Gendre B. (UVI - Etelman Obs.) report:
We imaged the field of GRB 160714A detected by SWIFT (trigger 704310) with the TAROT robotic telescope (D=25cm) located at the Calern observatory, France.
The observations started 40s after the GRB trigger (20s after the notice). The elevation of the field decreased from 34 degrees above horizon and weather conditions were good.
The first image is trailed with a duration of 60.0s (see the description in Klotz et al., 2006, A&A 451, L39). We do not detect any OT with a limiting magnitude of: t0+40.0s to t0+100.0s : Rlim = 16.3
The second image is 30.0s exposure in tracking mode: t0+115.7s to t0+145.7s : Rlim = 17.5
We co-added a series of exposures: t0+115.7s to t0+412.9s : Rlim = 18.9
Magnitudes were estimated with the nearby USNO-B1 stars and are not corrected for galactic dust extinction.

M. H. Siegel (PSU)reports on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 160714A 1682 s after the BAT trigger (Siegel et al., GCN Circ. 19697). No optical afterglow consistent with the BAT position is detected in the UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first finding chart (FC) exposure and subsequent exposures are:

The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.02 in the direction of the burst (Schlegel et al. 1998).

The AMI Large Array robotically triggered on the Swift alert for GRB 160714A (Siegel et al., GCN 19697) as part of the 4pisky program, and subsequent follow up observations were obtained up to 10 days post-burst. Our observations at 15 GHz on 2016 Jul 14.65, Jul 17.85, and Jul 21.85 (UT) do not reveal any variable radio source within the BAT error circle (Palmer et al., GCN 19705), with 3sigma upper limits of 150 uJy, 213 uJy, and 132 uJy respectively.
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 available at http://4pisky.org/ami-grb/.
