Romano (INAF-OAB), T. Sakamoto (NASA/ORAU), M. Stamatikos (NASA/ORAU) and L. Vetere (ASDC) report on behalf of the Swift Team:
At 15:12:00 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060714 (trigger=219101). Swift slewed immediately to the burst. The BAT on-board calculated location is 227.872, -6.546 (15h 11m 29s, -06d 32' 45") (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak with a duration ~20 seconds. The peak count rate was ~500 counts/sec (15-350 keV).
The XRT began observing the field at 15:13:39 UT, 99 seconds after the BAT trigger. XRT found a bright, fading, uncatalogued X-ray source located at RA(J2000) = 15h 11m 26.5s, Dec(J2000) = -06d 33' 57.5", with an estimated uncertainty of 4.7 arcseconds (90% confidence radius). This location is 83 arcseconds from the BAT on-board position, within the BAT error circle. The initial flux in the 2.5s image was 1.0e-08 erg/cm2/s (0.2-10 keV).
UVOT took a finding chart exposure of 100 seconds with the White (160-650 nm) filter starting 109 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at (RA,DEC) (J2000) of (227.8602,-6.5662) or (15h11m26.45s,-06o33'58.3") with a 1-sigma error radius of about 0.5 arc sec. This position is 2.0 arc sec. from the center of the XRT error circle. The estimated magnitude is 19.2 with a 1-sigma error of about 0.5 mag. No correction has been made for the expected extinction corresponding to E(B-V) of 0.08.

"We have observed the field covering the error circle of GRB060714 (GCN 5311) with the unfiltered CCD camera on the 30-cm telescope at University of Miyazaki. The observation was started 15:48:11 UT on Jul. 14. After co-adding a set of 5 images (15:48:11 - 15:52:41 UT) of 30 sec exposures, we have compared with the USNO A2.0 catalog. Preliminary analysis shows there is no new source brighter than 17.1 mag. in the position reported by H.A.Krimm et al.(GCN 5311)"

A. Stefanescu, G. Kanbach, S. Duscha, F. Schrey, M. Muehlegger, N. Prymak, H. Steinle (MPE Garching) of the OPTIMA-Burst Team report the following:
"OPTIMA-Burst at the 1.3m Skinakas Observatory, of the University of Crete, Greece observed the Swift UVOT-Errorcircle of GRB 060714 at 19:53UT (4:42h after the Burst).
We detected a faint source at the UVOT-Position (GCN Circular #5311). We estimate the brightness of this source in a 10min white-light image as 19.9+-.5mag. The position overlaps the UVOT errorcircle. There is no source at this position in the USNO-A2 Catalog, and no minor planet according to MPChecker.

We observed error box of GRB060724 (Krimm et al., GCN5311) with Shajn 2.6m telescope of CrAO. A set of 60 sec R-exposures was taken between July 14 (UT) 19:09 - 19: 40. At the position of the OT candidate (Krimm et al., GCN5311; Stefanescu GCN5314) we found an optical source. The source is clearly visible on a combined image 28x60 sec. A photometry of the source against USNO A2.0 is 19.9 +/-0.03. The photometry is preliminary.
The finding chart can be found in http://grb.rssi.ru/GRB060714/grb060714_ZTSh_R.gif
We also detect the source in Maidanak 1.5m R-images (exposure 120 s) started on July 14 (UT) 16:05 and do not detect OT on single B-images (exposure 120 s). A photometry of this observation is not available yet.

Pall Jakobsson (U. Hertfordshire), Paul Vreeswijk (ESO), Johan P.U. Fynbo, Jens Hjorth (DARK, NBI), Rhaana Starling (U. Amsterdam), D. Alexander Kann (TLS Tautenburg) and Dieter Hartmann (Clemson University) report on behalf of a larger collaboration:
Using FORS1 on the Very Large Telescope, we have obtained 3*30 min spectra (300V) of GRB 060714 (Krimm et al., GCN 5311). The acquisition image shows the UVOT optical afterglow candidate to have R ~ 20.4 on July 14.990 (8.54 hours post-burst).
The combined spectrum is rich of absorption features, including Ly-alpha, Ly-beta, S II, C II, C IV, Si II, Si IV, Fe II, Al II and Zn II, corresponding to a redshift of z = 2.71.
GCN Circular #5321
M. Perri, M.L. Conciatore, L. Vetere, M. Capalbi (ASDC), D.N. Burrows (PSU) report on behalf of the Swift/XRT team:
We have analyzed the first 9 orbits of XRT data from GRB 060714 (Krimm et al., GCN 5311). A 4.2 ks Photon Counting mode image provides a refined XRT position:
```
RA(J2000)  =  15h 11m 26.5s,
Dec(J2000) = -06d 33m 59.3s
```
with an uncertainty of 3.8 arcsec (90% containment). This position is 1.2 arcsec away from the on-board UVOT position of the optical afterglow reported in GCN 5311.
The X-ray light curve displays two flares during the first orbit at about 140 and 180 seconds after the BAT trigger. The afterglow decay from T+300s to T+40ks can be fit with a broken power-law with an initial decay slope of -0.4+/-0.2, a break at 3.7 (+1.7)(- 1.0) ks, and a post-break slope of -1.29+/-0.15.
A power-law fit to the 0.3-10 keV spectrum from T+107s to T+248s gives a photon index of 1.97+/-0.05 and a column density of (1.89+/-0.15)e21 cm**-2. We note the Galactic hydrogen column density in the direction of the burst is 6.7e20cm**-2.
If the burst continues decaying at the current rate we estimate a 0.3-10 keV unabsorbed flux of ~6e-13 ergs cm**-2 s**-1 at T+24hr.
This circular is an official product of the Swift XRT Team.

B. E. Cobb (Yale), part of the larger SMARTS consortium, reports:


Using the ANDICAM instrument on the 1.3m telescope at CTIO, we
obtained optical/IR imaging of the error region of GRB 060714
(GCN 5311, Krimm et al.) with a mid-exposure time of 2006-07-15 01:18 UT
(~10.1 hours post-burst). Total summed exposure times amounted to
36 minutes in I and 30 minutes in J.


The afterglow of GRB 060714 (GCN 5311, Krimm et al.) is well-detected
in the I-band, but only marginally detected in J.  The following
preliminary photometry was calibrated using several USNO-B1.0
stars in the I-band and several 2MASS standards in J.  The
I-band error is dominated by the error in the photometric
calibration, while the error in the J-band in dominated
by the error in the afterglow measurement.

G. Malaspina, L. Nicastro, E. Palazzi, E. Meurs, and P. Goldoni  
report on behalf of the REM/ROSS team:


We imaged the field of GRB 060714 (Krimm et al. GCN 5311) with the

of observations was performed automatically in the near infrared (J,  
H, K) starting on July 14.987 (about 8.5 hours after the BAT trigger)
for a total exposure time of 100 sec on each filter.


We do not detected the possible afterglow candidate reported by
Krimm et al. (GCN 5311) inside the X-ray refined error circle
(Perri et al. GCN 5321) down to a limiting magnitude of J > 16.5,
H > 16.1 and K > 15.3.

on behalf of the Swift-BAT team:


Using the data set from T-240 to T+962 sec from the telemetry downlinks,
we report further analysis of BAT GRB 060714 (trigger #219101)
(Krimm, et al., GCN Circ. 5311).  The BAT ground-calculated position is RA,Dec
= 227.854, -6.545 deg {15h 11m 24.9s, -6d 32' 42.3"} (J2000) +- 1.5 arcmin,
(radius, sys+stat, 90% containment).  The partial coding was 27%.


The mask-weighted lightcurves show an initial triangular-shapped peak
starting at T-15 sec, peaking at T_zero, and ending at T+55.  Then come
two peaks, each about 20 sec FWHM, peaking at T+76 and T+90 sec; the last peak
ending at T+120 sec.  We note that the XRT follow-up observation does not start
until the trailing edge of the second peak.  T90 (15-350 keV) is 115 +- 5 sec
(estimated error including systematics).


The time-averaged spectrum from T-13.3 to T+120.6 is best fit by a simple
power-law model.  The power law index of the time-averaged spectrum is
1.99 +- 0.10.  The fluence in the 15-150 keV band is 3.0 +- 0.2 x 10^-6 erg/cm2.
The 1-sec peak photon flux measured from T+75.42 sec in the 15-150 keV band
is 1.4 +- 0.1 ph/cm2/sec.  All the quoted errors are at the 90% confidence level.


We apologize for the long delay in issuing this standard BAT Second Circular.

Taking into account  early  Swift/UVOT  observations (Boyd et al., GCN5357)
one can suggest that during our observations the afterglow re-brightening
took place.

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).

Krimm: GRB 060714: No Clear Dividing Line Between Prompt Emission and X-ray Flares 
 
The long gamma-ray burst GRB 060714 was observed to exhibit a series of five
X-ray flares beginning ~70 s after the burst trigger T0 and continuing until T0
+ ~200 s. The first two flares were detected by the Burst Alert Telescope (BAT)
on the Swift satellite, before Swift had slewed to the burst location, while
the last three flares were strongly detected by the X-Ray Telescope (XRT) but
only weakly detected by the BAT. This burst provides an unusual opportunity to
track a complete sequence of flares over a wide energy range. The flares were
very similar in their light curve morphology, showing power-law rise and fall
components, and in most cases significant sub-structure. The flares also showed
strong evolution with time, both spectrally and temporally. The small time
scale and large amplitude variability observed are incompatible with an
external shock origin for the flares, and support instead late time sporadic
activity either of the central source or of localized dissipation events within
the outflow. We show that the flares in GRB 060714 cannot be the result of
internal shocks in which the contrast in the Lorentz factor of the colliding
shells is very small, and that this mechanism faces serious difficulties in
most Swift GRBs. The morphological similarity of the flares and the prompt
emission and the gradual and continual evolution of the flares with time makes
it difficult and arbitrary to draw a dividing line between the prompt emission
and the flares.
