S. T. Holland (CRESST/USRA/GSFC), S. D. Barthelmy (GSFC), D. N. Burrows (PSU), J. R. Cummings (NASA/UMBC), V. D'Elia (ASDC), B. Gendre (ASDC), C. Gronwall (PSU), H. A. Krimm (CRESST/GSFC/USRA), C. B. Markwardt (NASA/GSFC), D. M. Palmer (LANL), P. Romano (INAF-IASFPA), M. H. Siegel (PSU) and E. Troja (NASA/GSFC/ORAU) report on behalf of the Swift Team:
At 15:24:29 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 110709A (trigger=456939). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 238.895, +40.898, which is
```
   RA(J2000)  =  15h 55m 35s
   Dec(J2000) = +40d 53' 51"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows 8 roughly equal bright peaks with a total duration of about 50 sec. The peak count rate was ~12,000 counts/sec (15-350 keV), at ~18 sec after the trigger.
The XRT began observing the field at 15:25:34.7 UT, 65.6 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 238.8931, +40.9232 which is equivalent to:
```
   RA(J2000)  = 15h 55m 34.34s
   Dec(J2000) = +40d 55' 23.5"
```
with an uncertainty of 4.9 arcseconds (radius, 90% containment). This location is 92 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy.
UVOT took a finding chart exposure of 150 seconds with the White filter starting 73 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. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.02.
Burst Advocate for this burst is S. T. Holland (Stephen.T.Holland AT 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.)

P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team:
Using promptly downlinked XRT event data for GRB 110709A, we find an enhanced XRT position of the afterglow: RA, Dec: 238.8911, 40.9244 which is equivalent to:
```
   RA (J2000)  = 15 55 33.86
   Dec (J2000) = +40 55 28.0
```
with an uncertainty of 2.0 arc sec (radius, 90% confidence). Analysis of the promptly available data is online at http://www.swift.ac.uk/sper/456939.
Position enhancement is is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177).

J.P. Osborne, A.P. Beardmore, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team.
Using 3951 s of XRT Photon Counting mode data and 7 UVOT images for GRB 110709A, 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 = 238.89144, +40.92427 which is equivalent to:
```
RA (J2000): 15h 55m 33.95s
Dec (J2000): +40d 55' 27.4"
```
with an uncertainty of 1.5 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).

Markwardt (GSFC), D. M. Palmer (LANL), 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+733 sec from recent telemetry downlinks, we report further analysis of BAT GRB 110709A (trigger #456939) (Holland, et al., GCN Circ. 12118). The BAT ground-calculated position is RA, Dec = 238.895, 40.918 deg, which is
```
   RA(J2000)  =  15h 55m 34.8s 
   Dec(J2000) = +40d 55' 06.4" 
```
with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 91%.
The mask-weighted light curve shows at least 8 peaks starting at T-5 sec, with the brightest peak at ~T+34 sec, and returning to background at ~T+100 sec. T90 (15-350 keV) is 44.7 +- 1.0 sec (estimated error including systematics).
The time-averaged spectrum from T-4.3 to T+65.5 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.24 +- 0.03. The fluence in the 15-150 keV band is 1.0 +- 0.02 x 10^-05 erg/cm2. The 1-sec peak photon flux measured from T+34.31 sec in the 15-150 keV band is 6.2 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

GCN Circular #12133
V. Connaughton (UAH) reports on behalf of the Fermi GBM Team:
"At 15:24:27.37 UT on 09 July 2011, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 110709A (trigger 331917869 / 110709642), which was also detected by the Swift/BAT (Holland et al. 2011, GCN 12118) and the Swift/XRT (Evans et al. 2011, GCN 12119). The GBM on-ground location is consistent with the Swift position.
The angle from the Fermi LAT boresight at trigger time was 54 degrees. Approximately 6 - 200 s from trigger time, the Fermi spacecraft executed an automatic maneuver in response to a command from GBM, in order to place the burst closer to the LAT boresight, and observed this position for the following 2.5 hours, subject to Earth limb constraints.
The GBM light curve shows several bright peaks from trigger time to 50-s post-trigger, with a duration (t90) of 43.5 s (50-300 keV). The time-averaged spectrum from T0-4.096 s to T0+62.5 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -1.16 +/- 0.02 and the cutoff energy, parametrized as Epeak, is 533 +/- 37 keV.
The event fluence (10-1000 keV) in this time interval is (4.43 +/- 0.07)E-5 erg/cm^2. The 64 ms peak photon flux measured starting from T0+25.28 s in the 10-1000 keV band is 15.4 +/- 1.7 ph/s/cm^2.
The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."

S. Golenetskii, R.Aptekar, D. Frederiks, E. Mazets, V. Pal'shin, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team, report:
The long GRB 110709A (Swift-BAT trigger #456939: Holland et al., GCN 12118; Sakamoto et al., GCN 12127) triggered Konus-Wind at T0=3D55470.576s UT (15:24:30.062)
The burst light curve consists of several partially overlapped pulses, a total duration of the burst ~60 s. The emission is seen up to ~5 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB110709_T55470/
As observed by Konus-Wind the burst had a fluence of (3.7 =B1 0.3)x10-5 erg/cm2, and a 256-ms peak flux, measured from T0+12.544 s, of (4.1 =B1 0.4)x10-6 erg/cm2/s (both in the 20 keV - 5 MeV energy range).
The time-integrated spectrum of the burst (measured from T0 to T0+48.896 s) is best fitted in the 20 keV - 5 MeV range by a power law with exponential cutoff model, for which alpha =3D -1.03 (-0.07, +0.07), and Ep =3D 356(-34, +42) keV, chi2 =3D 72.6/76 dof.
The spectrum at the maximum count rate (measured from T0+7.963 to T0+16.128 s) is best fitted in the 20 keV - 5 MeV range by a power law with exponential cutoff model, for which alpha =3D -0.72 (-0.12, +0.13), and Ep =3D 523(-68, +87) keV, chi2 =3D 72.4/76 dof.
All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.

G. Stratta (ASDC), V. D'Elia (ASDC) and S. T. Holland (CRESST/USRA/GSFC) report on behalf of the Swift-XRT team:
We have analysed 9.6 ks of XRT data for GRB 110709A (Holland et al. GCN Circ. 12118), from 71 s to 19.3 ks after the BAT trigger. The data comprise 565 s in Windowed Timing (WT) mode with the remainder in Photon Counting (PC) mode. The enhanced XRT position for this burst was given by Osborne et al. (GCN. Circ 12119).
The late-time light curve (from T0+5.2 ks) can be modelled with a power-law decay with a decay index of alpha=1.72 (+/-0.10).
A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 2.21 (+0.09, -0.08). The best-fitting absorption column is 7.5 (+0.6, -0.5) x 10^21 cm^-2, in excess of the Galactic value of 1.5 x 10^20 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 2.07 (+/-0.11) and a best-fitting absorption column of 7.3 (+/-0.7) x 10^21 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 5.0 x 10^-11 (1.0 x 10^-10) erg cm^-2 count^-1.
A summary of the PC-mode spectrum is thus:
```
Total column:	     7.3 (+/-0.7) x 10^21 cm^-2
Galactic foreground: 1.5 x 10^20 cm^-2
Excess significance: 17.8 sigma
Photon index:	     2.07 (+/-0.11)

J. Kelemen,(Konkoly Obs.) on behalf of the GRB OT observing program at the Konkoly Observatory.
We observed the field of GRB 110709A (trigger=456939) S. T. Holland et al. (GCN 12118) using the enhanced Swift-XRT position provided by P. A. Evans. (GCN 12119) with a 60/90 cm Schmidt telescope located at the Mountain Station of the Konkoly Observatory. We coadded 6 red sensitive CCD images without filter with 300 sec exposure time each. On the coadded frame we checked the position RA (J2000) = 15:55:33.86 Dec (J2000) = +40:55:28.0 provided by J. P. Osborne et al. (GCN 12123). We found a faint marginaly visible source at the position RA (J2000) = 15:55:33.96 Dec (J2000) = +40:55:27.7 within the error circle of the astrometricaly corrected X-ray position. Based on nearby UCAC-3 stars the brightness of this object in the R band is 21.4 +/- 0.2 magnitude.

Nakazawa, K. Makishima (Univ. of Tokyo), on behalf of the Suzaku WAM team, report:
The bright long GRB110709A (Swift/BAT trigger #456939, GCN 12118; Holland et al.) triggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV at 15:24:27.951 UT (=T0).
The observed light curve shows multiple peaks starting at T0 s, ending at T0+45 s, with a duration (T90) of about 41.5 seconds. The fluence in 100 - 1000 keV was 2.02 (-0.26, +0.10) x 10^-5 erg/cm^2. The 1-s peak flux measured from T0+7 s was 4.10 (-0.96, +0.10) photons/cm^2/s in the same range.
Preliminary result shows that the time-averaged spectrum from T0 s to T0+45 s is well fitted by a power-law with exponential cutoff model:
```
 dN/dE ~  E^{-alpha} * exp(-(2-alpha)*E/Epeak) with
 alpha       1.37 (-0.61, +0.49), and
 Epeak       431 (-113, +173) keV (chi^2/d.o.f. = 18.0/12).
```
We also shows the results with the same spectrum fitted by a GRB Band model fixing beta of 2.5, the low-energy photon index alpha: 1.34 (-0.49, +0.74) and the peak energy Epeak: 407 (-96, +158) keV (chi^2/d.o.f = 17.4/12). All the quoted errors are at statistical 90% confidence level.
