GCN Circular #16546
L. M. Z. Hagen (PSU), S. D. Barthelmy (GSFC), S. B. Cenko (GSFC), M. M. Chester (PSU), J. R. Cummings (NASA/UMBC), N. Gehrels (NASA/GSFC), J. A. Kennea (PSU), H. A. Krimm (CRESST/GSFC/USRA), F. E. Marshall (NASA/GSFC), D. M. Palmer (LANL), T. Sakamoto (AGU), B. Sbarufatti (INAF-OAB/PSU) and M. H. Siegel (PSU) report on behalf of the Swift Team:
At 01:13:41 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 140709A (trigger=603810). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 304.639, +51.223 which is
```
   RA(J2000) = 20h 18m 33s
   Dec(J2000) = +51d 13' 23"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows several peaks with a total duration of about 80 sec. The peak count rate was ~2800 counts/sec (15-350 keV), at ~0 sec after the trigger.
The XRT began observing the field at 01:15:04.0 UT, 82.9 seconds after the BAT trigger. Using promptly downlinked data we find a bright, uncatalogued X-ray source located at RA, Dec 304.66332, 51.22316 which is equivalent to:

with an uncertainty of 3.7 arcseconds (radius, 90% containment). This location is 54 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 1.01e-08 erg cm^-2 s^-1 (0.2-10 keV).
UVOT took a finding chart exposure of 150 seconds with the White filter starting 92 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of the XRT error circle. The typical 3-sigma upper limit has been about 19.6 mag. Results from the list of sources generated on-board are not available at this time. No correction has been made for the expected extinction corresponding to E(B-V) of 0.40.

We observed the field of GRB 140709A (Hagen, et al., GCN 16546) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astron=C3=B3mico Nacion= al on Sierra San Pedro M=C3=A1rtir from 2014/07 9.17 to 2014/07 9.25 UTC (2.76 = to 4.78 hours after the BAT trigger), obtaining a total of 1.42 hours exposure in the r and i bands and 0.60 hours exposure in the Z, Y, J, and H bands.
We detect no sources within the Swift-XRT error circle. In comparison wi= th 2MASS, we obtain the following upper limits (3-sigma):
```
  r > 23.39
  i > 23.20
  Z > 22.17
  Y > 21.61
  J > 21.55
  H > 21.13
```
These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB. We note that a faint, red source is detected just outside the XRT error region at a position:
RA, DEC =3D 304.661780, 51.224069 +/- 0.5" (J2000), with
```
  r > 23.08
  i =3D 22.15 +/- 0.13
  Z =3D 21.43 +/- 0.18
  Y > 21.25
  J =3D 20.90 +/- 0.20
  H =3D 20.76 +/- 0.25
```
We cannot confirm fading in this source. We thank the staff of the Observatorio Astron=C3=B3mico Nacional in San Pedro M=C3=A1rtir.

P.A. Evans, M.R. Goad, J.P. Osborne and A.P. Beardmore (U. Leicester) report on behalf of the Swift-XRT team.
Using 1569 s of XRT Photon Counting mode data and 4 UVOT images for GRB 140709A, 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 = 304.66235, +51.22497 which is equivalent to:
```
RA (J2000): 20h 18m 38.96s
Dec (J2000): +51d 13' 29.9"
```
with an uncertainty of 1.6 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).

N. P. M. Kuin (UCL-MSSL) and L. M. Z. Hagen (PSU) report on behalf of the Swift/UVOT team:
The Swift/UVOT began settled observations of the field of GRB 140709A 93 s after the BAT trigger (Hagen et al., GCN Circ. 16546). No optical afterglow consistent with the XRT position (Evans et al. GCN Circ. 16548) is detected in the initial 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:
```

V. D'Elia (ASDC), M. de Pasquale (INAF-IASFPA), V. Mangano (PSU), M.C. Stroh (PSU), D.N. Burrows (PSU), P.A. Evans (U. Leicester), B.P. Gompertz (U. Leicester), J.P. Osborne (U. Leicester), A. Maselli (INAF-IASFPA) and L.M.Z. Hagen report on behalf of the Swift-XRT team:
We have analysed 7.1 ks of XRT data for GRB 140709A (Hagen et al. GCN Circ. 16546), from 75 s to 30.7 ks after the BAT trigger. The data comprise 195 s in Windowed Timing (WT) mode (the first 6 s were taken while Swift was slewing) with the remainder in Photon Counting (PC) mode.
The late-time light curve (from T0+5.7 ks) can be modelled with a power-law decay with a decay index of alpha=0.89 (+0.08, -0.09).
A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 2.48 (+/-0.07). The best-fitting absorption column is 9.9 (+/-0.5) x 10^21 cm^-2, in excess of the Galactic value of 4.1 x 10^21 cm^-2 (Willingale et al. 2013). The PC mode spectrum has a photon index of 1.88 (+/-0.14) and a best-fitting absorption column of 8.0 (+1.2, -1.1) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 4.9 x 10^-11 (8.0 x 10^-11) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     8.0 (+1.2, -1.1) x 10^21 cm^-2
Galactic foreground: 4.1 x 10^21 cm^-2
Excess significance: 5.8 sigma
Photon index:	     1.88 (+/-0.14)
```
If the light curve continues to decay with a power-law decay index of 0.89, the count rate at T+24 hours will be 0.038 count s^-1, corresponding to an observed (unabsorbed) 0.3-10 keV flux of 1.9 x 10^-12 (3.1 x 10^-12) erg cm^-2 s^-1.

Using the data set from T-239 to T+626 sec from the recent telemetry downlink, we report further analysis of BAT GRB 140709A (trigger #603810) (Hagen, et al., GCN Circ. 16546). The BAT ground-calculated position is RA, Dec = 304.666, 51.222 deg which is
```
    RA(J2000)  =  20h 18m 39.9s
    Dec(J2000) = +51d 13' 17.8"
```
with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 61%.
The mask-weighted light curve shows a complex structure. Burst activity begins at T-50 sec, with a gradual rise to a peak at T+0 sec, punctuated by several subsidiary peaks. Then there is a return to near background by T+8 sec, followed by a second main peak at T+15 sec. There are additional smaller and softer peaks centered at T+55 and T+75 sec. T90 (15-350 keV) is 98.6 +- 7.7 sec (estimated error including systematics).
The time-averaged spectrum from T-46.1 to T+93.4 sec is best fit by a power law with an exponential cutoff. This fit gives a photon index 1.23 +- 0.27, and Epeak of 78.0 +- 20.4 keV (chi squared 57.80 for 56 d.o.f.). For this model the total fluence in the 15-150 keV band is 5.2 +- 0.2 x 10^-6 erg/cm2 and the 1-sec peak flux measured from T+15.48 sec in the 15-150 keV band is 3.1 +- 0.3 ph/cm2/sec. A fit to a simple power law gives a photon index of 1.74 +- 0.06 (chi squared 69.09 for 57 d.o.f.). All the quoted errors are at the 90% confidence level.

Following the detection of GRB 140709A by Swift (Hagen et al., GCNC 16546), the 0.6m TELMA robotic telescope at the BOOTES-2 astronomical station Malaga (Spain), responded to the GRB location starting at 01:14:41 UT (i.e. 60s postburst, in the clear filter, 5s integrations), with an upper limit of R > 16.5. Further optical observations were carried out at the 1.5m OSN telescope starting on July 9.06-9.12 UT (i.e. 0.37--1.72 hours post GRB). A source coincident with the enhanced XRT position is found (Evans et al. GCN 16548) at coordinates RA(J2000) = 20:18:38.95, DEC(J2000) = 51:13:29.6 (+/-0.5") when the 78x60s frames are co-added. Using USNO-B1.0 as reference, we measure a Vega magnitude of I = 20.8 (uncorrected for Galactic reddening), which is the potential optical afterglow. At the present stage we do not know is the source is fading or not. We also detect the object reported by RATIR (Butler et al. GCN 16547), which is not consistent with the position of our candidate. Further observations are planned.

E. Burns (UAH) reports on behalf of the Fermi GBM Team:
"At 01:13:41.38 UT on 09 July 2014, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 140709A (trigger 426561224 / 140709051). which was also detected by the Swift/BAT (L. Hagen et al., GCN 16546) The GBM on-ground location is consistent with the Swift position.
The angle from the Fermi LAT boresight is 111 degrees.
The GBM light curve consists of two main peaks with a duration (T90) of about 70s (50-300 keV). The time-averaged spectrum from T0-25 s to T0+45 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.10 +/- 0.07 and the cutoff energy, parameterized as Epeak, is 126 +/- 9 keV
The event fluence (10-1000 keV) in this time interval is (8.8 +/- 0.4)E-06 erg/cm^2. The 1-sec peak photon flux measured starting from T0+15.0 s in the 10-1000 keV band is 5.2 +/- 0.3 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

G. Masi, the Virtual Telescope Project - Italy, reports:
I started observations of GRB 140709A (Hagen et al. GCN 16546) with the 17" robotic unit part of the Virtual Telescope (Ceccano, Italy) at 02:04:00 UT, 3000 seconds after the burst.
An optical source is visible where described by Castro-Tirado et al. (GCN 16554) in a image coming from the sum of three, 180-seconds exposures, unfiltered. The position of the source is RA: 20h18m38.94s +51d13'29.9" (J2000.0, mean residuals of 0.2") and the magnitude was estimated to be 21.0, assuming R mags for the reference stars from UCAC-4.

The field of GRB 140709A (Hagen et al. GCNC 16546) was observed in i'-band with the 10.4m GTC telescope in two epochs centered on July 9.12955 and 10.10966 UT (1.9 and 25.4 hours post burst). Comparison between those two epochs reveals that the optical candidate reported by Castro-Tirado et al. (GCNC 16554) has faded by ~0.7 mags (from i'~21.3 to 22.0, both in AB), implying a shallow decay index of ~0.2. A similar decay is measured in z'-band.

These magnitudes are in the AB system and are not corrected for Galactic extinction in the direction of the GRB. Upper limits are 3-sigma. We cannot reliably confirm fading in this source. We note that another RATIR source outside of the Swift XRT error region (see, GCN 16547) does not appear to fade and is not likely to be the afterglow to GRB 140709A.

We observed the position of GRB 140709A (GCN 16546) at 15 GHz with the Arcminute Microkelvin Imager (AMI-LA) starting on 2014 July 11.93 to 12.10 UT, corresponding to 2.88 days post-burst. We have detected a possible radio counterpart consistent with the UVOT-enhanced XRT position (GCN 16548) with a preliminary flux of 0.35 +/- 0.06 mJy. However, this source is blended with the nearby NVSS source 201841+511349 lying at an angular distance of 27.5 arcseconds. The angular resolution of AMI is ~30 arcseconds. The flux was calculated by first subtracting the contribution from the NVSS source. Earlier AMI observations an 2014 July 9.05 to 9.14 UT and July 10.04 to 10.2, corresponding to <5 minutes and 1 day post-burst, did not detect a radio source at the position of the GRB with 3 sigma upper limits of 0.30 and 0.21 mJy, respectively. Further AMI monitoring is planned. We thank the AMI staff for scheduling these observations.
