At 11:50:43 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 080702 (trigger=315710). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 312.853, +72.308 which is
```
   RA(J2000) = 20h 51m 25s
   Dec(J2000) = +72d 18' 28"
```
with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with the second peak larger and a total duration of about 1.5 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0.5 sec after the trigger, during the second peak.
The XRT began observing the field at 11:51:50.0 UT, 66.3 seconds after the BAT trigger. Using promptly downlinked data we find a fading, uncatalogued X-ray source with an enhanced position: RA, Dec 313.05101, 72.31271 which is equivalent to:
```
   RA(J2000)  = 20h 52m 12.24s
   Dec(J2000) = +72d 18' 45.8"
```
with an uncertainty of 3.0 arcseconds (radius, 90% containment). This location is 217 arcseconds from the BAT onboard position, slightly outside the BAT error circle.
A power-law fit to a spectrum formed from promptly downlinked event data gives a column density consistent with the Galactic value of 1.53e+21 cm^-2 (Kalberla et al. 2005).
UVOT took a finding chart exposure of 100 seconds with the White (160-650 nm) filter starting 72 seconds after the BAT trigger. No afterglow candidate has been found in the initial data products. The XRT position is outside the 2.7'x2.7' sub-image. 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 0.67.
Burst Advocate for this burst is M. De Pasquale (mdp AT mssl.ucl.ac.uk). 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.R. Goad, J.P. Osborne, A.P. Beardmore and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team.
Using 95 s of overlapping XRT Photon Counting mode and UVOT data for GRB 080702A, 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 = 313.05081, +72.31271 which is equivalent to:
```
RA (J2000): 20h 52m 12.20s
Dec (J2000): +72d 18' 45.8"
```
with an uncertainty of 1.9 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 http://www.swift.ac.uk/xrt_positions/Goad.pdf), the current algorithm is an extension of this method.

GCN Circular #7925
K.L. Page (U. Leicester) & M. De Pasquale (UCL-MSSL) report on behalf of the Swift-XRT team:
We have analysed the first 3 orbits of Swift-XRT data obtained for GRB 080702A (De Pasquale et al., GCN Circ. 7920), covering 5.2 ks of Photon Counting mode data, between ~75 and 12.6 ks after the trigger. The UVOT-enhanced XRT position was given by Goad et al. in GCN Circ. 7923.
The light-curve can be modelled by a broken power-law, with a flat decay of alpha = 0.5 +/- 0.3 until around the end of the first orbit of data. At this point, the decay steepens to 1.6 +0.9/-0.3. The afterglow is already faint by the end of the third orbit.
A spectrum extracted from the first orbit of data can be modelled with an absorbed power-law, with Gamma = 2.05 +0.71/-0.64 and NH = (6.2 +5.4/-3.6)x10^21 cm^-2, in excess of the Galactic column in this direction of 1.53x10^21 cm^-2. The observed (unabsorbed) flux over this time interval (75-800 s post-trigger) is 5.7x10^-12 (1.0x10^-11) erg cm^-2 s^-1.
If the light-curve continues to decay with alpha ~ 1.6, the count rate 24 hours after the burst is estimated to be 3.3x10^-5 count s^-1, which corresponds to an observed flux of 2x10^-15 erg cm^-2 s^-1.
This is an official product of the Swift-XRT team.

Palmer (LANL), M. De Pasquale (UCL-MSSL), T. Sakamoto (GSFC/UMBC), G. Sato (ISAS), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC), T. Ukwatta (GWU) (i.e. the Swift-BAT team):
Using the data set from T-120 to T+182 sec from recent telemetry downlinks, we report further analysis of BAT GRB 080702A (trigger #315710) (De Pasquale, et al., GCN Circ. 7920). The BAT ground-calculated position is RA, Dec = 313.049, 72.278 deg, which is
```
   RA(J2000)  =  20h 52m 11.8s 
   Dec(J2000) = +72d 16' 39.7" 
```
with an uncertainty of 3.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 81%.
The mask-weighted light curve shows a weak single spike. T90 (15-350 keV) is 0.5 +- 0.2 sec (estimated error including systematics).
The time-averaged spectrum from T-0.0 to T+0.5 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.34 +- 0.42. The fluence in the 15-150 keV band is 3.6 +- 1.0 x 10^-8 erg/cm2. The 1-sec peak photon flux measured from T-0.22 sec in the 15-150 keV band is 0.7 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

Y.A. Mori, T. Shimokawabe, Y. Kudou, H. Nakajima and N. Kawai (Tokyo Tech) report on behalf of the MITSuME collaboration:
The 3-color 50cm MITSuME Telescope at Akeno, Japan, responded to GRB 080702A (de Pasquale et al. GCN 7920) at 43 sec after the trigger, though we obtained the first sky image 20 min after the trigger due to the poor sky condition with frequent cloud coverage. In the co-added images of Ic, Rc, and g' bands, we did not detect any afterglow candidate in the XRT error circle. The 3-sigma limiting magnitudes based on USNO-B1.0 (I-band) and NOMAD (R-band,g'-band) stars are following.
```

GCN Circular #7932
M. De Pasquale (MSSL/UCL) on the behalf of the Swift/UVOT team:
The Swift/UVOT began settled exposures of the field of GRB080702A 73s after the BAT trigger (De Pasquale et al., GCN Circ. 7920). We do not find any newsource in any of the exposures inside the enhanced XRT error circle (Goad et al., GCN Circ. 7923).
The 3-sigma upper limits for detecting a source in the first finding chart (FC) exposure and co-added frames are:
```

The values quoted above are not corrected for the expected high Galactic extinction corresponding to a reddening of E(B-V) = 0.67 mag in the direction of the burst (Schlegel et al. 1998).
