GCN Circular #16531
F. E. Marshall (NASA/GSFC), S. D. Barthelmy (GSFC), S. B. Cenko (GSFC), J. R. Cummings (NASA/UMBC), J. A. Kennea (PSU), K. L. Page (U Leicester) and D. M. Palmer (LANL) report on behalf of the Swift Team:
At 19:33:33 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140706A (trigger=603587). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 49.306, -38.059 which is
```
   RA(J2000) = 03h 17m 13s
   Dec(J2000) = -38d 03' 33"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows two main peaks with a total duration of about 55 sec. The peak count rate was ~1700 counts/sec (15-350 keV), at ~0 sec after the trigger.
The XRT began observing the field at 19:34:46.0 UT, 72.8 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 49.29517, -38.05083 which is equivalent to:
```
   RA(J2000)  = 03h 17m 10.84s
   Dec(J2000) = -38d 03' 03.0"
```
with an uncertainty of 4.1 arcseconds (radius, 90% containment). This location is 42 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 5.09e-10 erg cm^-2 s^-1 (0.2-10 keV).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 82 seconds after the BAT trigger. There is a candidate afterglow in the list of sources generated on-board at
```
  RA(J2000)  =	03:17:10.40 =  49.29332
  DEC(J2000) = -38:03:07.4  = -38.05205
```
with a 90%-confidence error radius of about 1.10 arc sec. This position is 4.5 arc sec. from the center of the XRT error circle. The estimated magnitude is 19.05. No correction has been made for the expected extinction corresponding to E(B-V) of 0.02.
Burst Advocate for this burst is F. E. Marshall (marshall AT milkyway.gsfc.nasa.gov). 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.)

GCN Circular #16532
A.P. Beardmore, P.A. Evans, M.R. Goad and J.P. Osborne (U. Leicester) report on behalf of the Swift-XRT team.
Using 1464 s of XRT Photon Counting mode data and 1 UVOT images for GRB 140706A, 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 = 49.29426, -38.05194 which is equivalent to:
```
RA (J2000): 03h 17m 10.62s
Dec (J2000): -38d 03' 07.0"
```
with an uncertainty of 1.8 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. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).
This circular was automatically generated, and is an official product of the Swift-XRT team.
GCN Circular #16534
P. Schady (MPE Garching), S. Klose (TLS Tautenburg) and J.Greiner (MPE Garching) report on behalf of the GROND team:
We observed the field of GRB 140706A (Swift-603587; Marshall et al., GCN #16531) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at ESO La Silla Observatory (Chile).
Observations started at 09:01UT on 7th-July, 13.5 hours after the GRB trigger, and are continuing. They were performed at an average seeing of 1.3" and at an average airmass of 1.5.
We found a single point source within the 2.2" Swift-XRT enhanced error circle reported by Beardmore et al. (GCN #16532) consistent with the UVOT position (Marshall et al., GCN #16531).
Based on the first 8 min exposure, we estimate preliminary magnitudes (all in AB system) of
```
g' = 22.4 +/- 0.1 mag,
r' = 22.1 +/- 0.1 mag,
i' = 21.9 +/- 0.1 mag,
z' = 21.5 +/- 0.1 mag,
J > 20.9 mag,
H > 20.3 mag, and
K > 18.8 mag.
```
Given magnitudes are calibrated against GROND zeropoints as well as 2MASS field stars and are not corrected for the expected Galactic foreground extinction corresponding to a reddening of E_(B-V)=3D0.02 mag in the direction of the burst (Schlegel et al. 1998).
GCN Circular #16537
Bin-Bin Zhang (UAH) reports on behalf of the Fermi GBM Team:
"At 19:33:33.86 UT on 06 July 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140706A (trigger 426368016 / 140706815) which was also detected by Swift (Marshall et al. 2014, GCN 16531). The GBM on-ground location, using the Fermi GBM trigger data, is consistent with the Swift/BAT location.
The GBM light curve consists of two main peaks with a total duration=C2=A0 of about =C2=A047.5 s (50-300keV). The time-averaged spectrum from T0-18 = s=C2=A0 to T0+39 s is well fit by a power law function with an exponential=C2=A0 high-energy cutoff. The power law index is -1.37 +/- 0.15 and the=C2=A0 cutoff energy, parameterized as Epeak, is 96 +/- 19 keV.
The event fluence (10-1000 keV) in this time interval is (2.95 +/- 0.28)E-06 erg/cm^2. The 1.024-sec peak photon flux measured starting from T0+0.58 s in the 10-1000 keV band is 2.9 +/- 0.2 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final=C2=A0 results will be published in the GBM GRB Catalog."
GCN Circular #16538
P. D'Avanzo (INAF-OAB), V. D'Elia (ASDC), M. de Pasquale (INAF-IASFPA), J.A. Kennea (PSU), V. Mangano (PSU), M.C. Stroh (PSU), A.P. Beardmore (U. Leicester), P.A. Evans (U. Leicester), B.P. Gompertz (U. Leicester) and F.E. Marshall report on behalf of the Swift-XRT team:
We have analysed 4.6 ks of XRT data for GRB 140706A (Marshall et al. GCN Circ. 16531), from 62 s to 34.8 ks after the BAT trigger. The data comprise 56 s in Windowed Timing (WT) mode (the first 9 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 Beardmore et al. (GCN Circ. 16532).
The light curve can be modelled with an initial power-law decay with an index of alpha=3.55 (+0.25, -0.26), followed by a break at T+219 s to an alpha of 0.62 (+/-0.06).
A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 1.84 (+0.20, -0.19). The best-fitting absorption column is 8.1 (+5.2, -4.6) x 10^20 cm^-2, in excess of the Galactic value of 2.2 x 10^20 cm^-2 (Willingale et al. 2013). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.6 x 10^-11 (4.1 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     8.1 (+5.2, -4.6) x 10^20 cm^-2
Galactic foreground: 2.2 x 10^20 cm^-2
Excess significance: 2.2 sigma
Photon index:	     1.84 (+0.20, -0.19)
```
If the light curve continues to decay with a power-law decay index of 0.62, the count rate at T+24 hours will be 0.015 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 5.6 x 10^-13 (6.4 x 10^-13) erg cm^-2 s^-1.

Marshall (NASA/GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), 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 140706A (trigger #603587) (Marshall, et al., GCN Circ. 16531). The BAT ground-calculated position is RA, Dec = 49.269, -38.058 deg which is
```
  RA(J2000)  =  03h 17m 04.6s 
  Dec(J2000) = -38d 03' 28.6" 
```
with an uncertainty of 1.1 arcmin, (radius, sys+stat, 90% containment). The partial coding was 77%.
The mask-weighted light curve shows several peaks starting at ~T-20 sec, peaking at ~T-15, ~T+1 and ~T+28 sec, and ending at ~T+40 sec. T90 (15-350 keV) is 48.3 +- 4.3 sec (estimated error including systematics).
The time-averaged spectrum from T-21.3 to T+39.6 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.8 +- 0.1. The fluence in the 15-150 keV band is 2.0 +- 0.1 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T-0.12 sec in the 15-150 keV band is 1.8 +- 0.2 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/603587/BA/
GCN Circular #16541
M. H. Siegel (PSU) and F. E. Marshall (NASA/GSFC) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 140706A 82 s after the BAT trigger (Marshall et al., GCN Circ. 16531). A fading source consistent with the XRT position (Beardmore et al. GCN Circ. 16532) is detected in the initial UVOT exposures.
The preliminary UVOT position is:
```
  RA  (J2000) =  03:17:10.39 =  49.29328 (deg.)
  Dec (J2000) = -38:03:07.8  = -38.05218 (deg.)
```
with an estimated uncertainty of 0.45 arc sec. (radius, 90% confidence).
Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are:
```
