Vanden Berk (PSU) report on behalf of the Swift Team:
At 21:30:19 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060707 (trigger=217704). Swift slewed immediately to the burst. The BAT on-board calculated location is RA,Dec 357.079, -17.923 {23h 48m 19s, -17d 55' 21"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single FRED-like peak at T_0 lasting about 30 sec. There is a hard precusor at T-45 sec. The total duration is ~75 sec. The peak count rate was ~1500 counts/sec (15-350 keV), at ~2 sec after the trigger.
The XRT began taking data at 21:32:20 UT, 122 seconds after the BAT trigger. The XRT on-board centroid algorithm did not find a source in the image and no prompt position is available. Down-linked data show a bright source at RA(2000)=23 48 19.00 DEC(2000):-17 54 21.8 with an error circle of 3.8". This position is 60" from the BAT position.
UVOT took a finding chart exposure of 100 seconds with the White (160-650 nm) filter starting 126 seconds after the BAT trigger. No afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 25% of the BAT error circle and 100% of the ground-determined XRT error circle. The typical 3-sigma upper limit has been about 18.5 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the BAT 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.

"The BOOTES-IR 0.6m telescope, located at IAA-CSIC Observatorio de Sierra Nevada in Granada (Spain), observed the SWIFT error box for GRB 060707 (Moretti et al. GCNC 5285). R-band observations started at 01:20 UT(3:50 h after the burst, when it became observable from our location). A limiting R-band magnitude of ~20 is derived for the afteglow at ~ 1:45 UT.

Using the data set from T-120 to T+182 sec from recent telemetry downlinks, we report further analysis of BAT GRB 060707 (trigger #217704) (Moretti, et al., GCN 5285). The BAT ground-calculated position is RA,Dec = 357.073, -17.908 deg {23h 48m 17.4s, -17d 54' 27.4"} (J2000) +- 1.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 43%.
The mask-tagged lightcurve consists of two peaks. The first starts at T-50 sec, peaks at ~T-40 and then returns to a minumum at T-18 sec where it start to rise for the beginning of the second peak. The second peaks at ~T+5sec and ends at ~T+40 sec. There is no apparent further emission out to T+1400 sec. T90 (15-350 keV) is 68 +- 5 sec (estimated error including systematics).
The time-averaged spectrum from T-50 to T+25 is best fit by a power law with an exponential cutoff. This fit gives a photon index 0.66 +- 0.63, and Epeak of 66 (-10/+25) keV (chi squared 64.0 for 56 d.o.f.). For this model the total fluence in the 15-150 keV band is 1.7 +- 0.2 x 10^-6 erg/cm2 and the 1-sec peak flux measured from T+3.05 sec in the 15-150 keV band is 1.1 +- 0.2 ph/cm2/sec. A fit to a simple power law gives a photon index of 1.68 +- 0.13 (chi squared 73.4 for 57 d.o.f.). All the quoted errors are at the 90% confidence level.

"OPTIMA-Burst at the 1.3m Skinakas Observatory, located on Crete, Greece observed the Swift XRT-Errorbox of GRB 060707 at 00:30 UT (3h after the Burst).
We detected a faint source at the edge of the XRT-error circle (GCN Circular #5285). We estimate the brightness of this source in a 10min white-light image as 20.3+-.5mag. The position of the source is RA 23:48:19 Dec -17:54:18.4 (J2000). There is no source at this position in the USNO-A2 Catalog, and no minor planet according to MPChecker.
This source seems compatible with the source reported in GCN Circular 5290"
GCN Circular #5293
C. Guidorzi (Univ Bicocca & INAF-OAB), A. Moretti (INAF-OAB), J. A. Kennea (PSU) on behalf of the Swift-XRT team:
We have analyzed the first two orbits of data of GRB060707 (Moretti et al 2006, GCN 5285). The XRT data set consists of 43 s exposure in Windowed Timing (WT) in the first orbit followed by 3.1 ks exposure in Photon Counting (PC).
The refined position of the source is
```
   RA  (2000) =  23h 48m 18.89s  
   Dec (2000) = -17d 54' 20.4"
```
with an uncertainty of 3.9 arcsec (90% containment).
This position is 2.1 arcsec from the XRT position first reported (Moretti et al 2006, GCN 5285), 3.7 arcsec from the IR optical afterglow candidate position (de Ugarte-Postigo et al., GCN 5290) and 22.4 arcsec from the BAT ground-calculated position (Stamatikos et al. 2006, GCN 5289).
The 0.3-10 keV X-ray light curve shows the typical steep-to-shallow decay, with an initial power-law index of alpha ~ 1.6, followed by alpha ~ 0.7, break time around 600s from the BAT trigger time.
The PC spectrum is well fitted by an absorbed power law with photon index 2.0 +/- 0.1 and N_H consistent with the Galactic value (1.8e20 cm^-2). The average 0.3-10 keV unabsorbed flux during the second orbit is 5.5e-12 erg cm^-2 s^-1.
Assuming alpha ~ 0.7, the extrapolated unabsorbed flux at 24 hours is 9e-13 erg cm^-2 s^-1.

Using FORS1 on the Very Large Telescope, we have obtained 3*30 min spectra (300V) of the GRB 060707 field (Moretti et al., GCN 5285). The acquisition image shows that the proposed optical afterglow (de Ugarte Postigo et al., GCN 5290) has faded by approximately two magnitudes. Using photometric zeropoints from the ESO webpages we estimate the afterglow magnitude to be R ~ 22.4 on July 9.329 (1.432 days post-burst).
The combined spectrum displays a strong absorption feature around 5386 AA, with the flux dropping substantially blueward of this feature. Associating it with Ly-alpha gives a redshift of z = 3.43 for the burst. At this redshift we find several other absorption features, including Ly-beta, Si II, Si IV, C IV, Al II and O III].

Jakobsson et al: HI column densities of z > 2 Swift gamma-ray bursts
Context: Before the launch of the Swift satellite, the majority of the gamma-ray burst (GRB) afterglows for which Ly-alpha was redshifted into the observable spectrum showed evidence for a damped Ly-alpha absorber. This small sample indicated that GRBs explode either in galaxies, or regions within them, having high neutral hydrogen column densities. Aims: To increase the spectroscopic sample of GRBs with z > 2 and hence establish the N(HI) distribution along GRB lines-of-sight. Methods: We have obtained six z > 2 GRB afterglow spectra and fitted the Ly-alpha absorption line in each case to determine N(HI). This has been complemented with 12 other Swift N(HI) values from the literature. Results: We show that the peak of the GRB N(HI) distribution is qualitatively consistent with a model where GRBs originate in Galactic-like molecular clouds. However, a systematic difference, in particular an excess of low column-density systems compared to the predictions, indicates that selection effects and conditions within the cloud (e.g. strong ionization) influence the observed N(HI) range. We also report the discovery of Ly-alpha emission from the GRB 060714 host, corresponding to a star-formation rate of approximately 0.8 M_Sun/year. Finally, we present accurate redshifts of the six bursts: z = 3.240 +/- 0.001 (GRB 050319), z = 2.198 +/- 0.002 (GRB 050922C), z = 3.221 +/- 0.001 (GRB 060526), z = 3.425 +/- 0.002 (GRB 060707), z = 2.711 +/- 0.001 (GRB 060714) and z = 3.686 +/- 0.002 (GRB 060906).
