At 05:12:13 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060607 (trigger=213823). Swift slewed immediately to the burst. The BAT on-board calculated location is RA,Dec 329.712, -22.506 {21h 58m 51s, -22d 30' 20"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a double-peaked structure with a duration of about 40 sec. The peak count rate was ~3000 counts/sec (15-350 keV), at ~0 sec after the trigger.
The XRT began observing the field at 05:13:18 UT, 65 seconds after the BAT trigger. XRT found a bright, variable, uncatalogued X-ray source located at RA(J2000) = 21h 58m 50.1s, Dec(J2000) = -22d 29' 49.9", with an estimated uncertainty of 4.7 arcseconds (90% confidence radius). This location is 33 arcseconds from the BAT on-board position, within the BAT error circle. The initial flux in the 2.5s image was 3.3e-09 erg/cm2/s (0.2-10 keV).
UVOT took a finding chart exposure of 100 seconds with the White (160-650 nm) filter starting 75 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 (329.7100,-22.4963) or (21h58m50.40s,-22o29'46.7") with a 1-sigma error radius of about 0.5 arc sec. This position is 4.7 arc sec. from the center of the XRT error circle. The estimated magnitude is 15.7 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 0.03.

We imaged the field of GRB 060607 (Ziaeepour et al. GCN 5233) the robotic 60-cm REM telescope located at La Silla (Chile. A first set of observations was performed automatically in the near infrared (J, H, K, z bands) starting on June 5:13:45UT.
A preliminary analysis reveals an uncatalogued source of H ~ 13.3 at RA,DEC = (21:58:50.4, -22:29:47).
Further observations are in progress.

PROMPT began observing the position of the XRT error circle (Ziaeepour et al., GCN 5233) 44 seconds after the GRB trigger, 25 seconds after the initial alert in Ugriz.
We confirm the presence of the bright, fading optical afterglow: in our initial r' image, we find the source to be r' ~ 16.3 at a mean time of 65 seconds after the burst. It then brightened to r' ~ 16 at 90-s, and by 140-s it had risen to a magnitude of r' ~ 14.5.
GCN Circular #5237
Cedric Ledoux (ESO), Paul Vreeswijk (U. of Chile/ESO), Alain Smette (ESO), Andreas Jaunsen (U. of Oslo), and Andreas Kaufer (ESO) report on behalf of a larger collaboration:
"We triggered Rapid-Response Mode VLT observations with the Ultraviolet and Visual Echelle Spectrograph (UVES) following the Swift detection of GRB 060607 (Ziaeepour et al., GCN 5233). A series of exposures were started at 5:19:52 UT, i.e. 7.5 minutes after the Swift/BAT trigger. The spectra cover the approximate wavelength range 330-670nm at a resolving power of about 7 km/s. A preliminary analysis shows the Lya forest up to a rather weak Lya line, as well as a CIV doublet at a redshift of z=3.082, the presumed GRB redshift. We also detect two probable intervening Damped Lya systems (DLAs) at z=3.050 and z=2.937.
It's a pleasure to thank the excellent support of the Paranal staff."

D. Perley, N. Butler, and Y. Kemper (UCB) report:
Starting at 2006-06-07 10:34 UT (5.37 hours after the trigger) we imaged the field of GRB060607 (GCN 5233) using the Lick 3m telescope equipped with the Gemini IR camera under high airmass conditions and intermittent clouds. We do not detect the afterglow (GCN 5233, GCN 5234) down to a preliminary limiting magnitude of J=17.2 (3 sigma) in a series of dithered exposures lasting 60 minutes.
GCN Circular #5240
Kim Page, Mike Goad & Andy Beardmore (U. Leicester) report on behalf of the Swift-XRT team:
We have analysed the first 3 orbits of X-ray data obtained for GRB 060607 (BAT trigger 213823; Ziaeepour et al., GCN 5233).
The data show 3 flares, superimposed on a decay of alpha_1 = 1.09 +/- 0.04. Around 740 seconds after the trigger, the slope flattens, becoming alpha_2 = 0.45 +/- 0.03.
The flares in the WT data show spectral evolution. The later PC data are well-fitted by a single power-law with Gamma = 1.64 +/- 0.07, with excess NH above the Galactic value. Taking the redshift to be 3.082 (Ledoux et al; GCN 5237), the intrinsic NH is (7.9 +3.8/-3.5)e21 cm^-2.
Assuming the shallow decay of alpha_2 = 0.37 continues, the count rate is estimated to be 0.49 count s^-1 at 24 hours. This corresponds to an observed (unabsorbed) flux of 2.22e-11 (2.44e-11) erg cm^-2 s^-1.

Using the data set from T-119.6 to T+182.5 sec from the recent telemetry downlink, we report further analysis of BAT GRB 060607 (trigger #213823) (Ziaeepour, et al., GCN 5233). The BAT ground-calculated position is (RA,Dec) = 329.712, -22.500 deg {21h 58m 50.8s, -22d 30' 0.0"} (J2000) +- 0.8 arcmin, (radius, sys+stat, 90% containment). The partial coding was 99%.
The mask weighted light curve consists of two overlapping FRED peaks from T-5 sec to T+40 sec. There is a second double peaked structure between T+95 sec and T+105 sec. T90 (15-350 keV) is 100 +- 5 sec (estimated error including systematics).
The time-averaged spectrum from T-14.1 to T+104.5 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.45 +- 0.07. The fluence in the 15-150 keV band is 2.6 +- 0.1 x 10^-06 erg/cm2. The 1-sec peak photon flux measured from T-0.97 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.
Using the redshift of 3.082 reported by Ledoux et al (GCN 5237) and a cosmology of Omega_M - 0.3, Omega_lamba = 0.7 H0 = 65, we find Eiso (1-1000 keV in the rest frame) to be 1.1 X 10^53 ergs. This is based on an extrapolation of the BAT power law fit into the corresponding observer energy band.

S. R. Oates (UCL-MSSL), A. J. Blustin (UCL-MSSL), H. Z. Ziaeepour (UCL-MSSL) report on behalf of the Swift/UVOT team:
The Swift/UVOT began observing the field of GRB 060607 at 05:15:12 on 2006-06-06, 179 s after the BAT trigger (Ziaeepour et al., GCN 5233). An optical counterpart was detected in the V-band at a position (RA,DEC) (21h 58m 50.4s, -22d 29' 47.4'') (J2000) to within 0.5 arcsec. The optical afterglow was detected in white, V, B and U filters. The non-detections in the UV bands is consistent with reported redshift z=3 (Ledoux et al., GCN 5237).

Jin: GRB 060418 and 060607A: the medium surrounding the progenitor and the weak reverse shock emission
We constrain the circum-burst medium profile with the rise behavior of the very early afterglow light curves of gamma-ray bursts (GRBs). Using this method, we find a constant and low-density medium profile for GRB 060418 and GRB 060607A, which is consistent with the inference from the late afterglow data. In addition, we show that the absence of the IR flashes in these two GRB afterglows is consistent with the standard external reverse shock model, which thus renders models like the highly magnetized GRB outflow being unnecessary to a certain extent.

Ziaeepour: GRB 060607A: A GRB with Bright Asynchronous Early $X$-ray and Optical Emissions
Abstract: The early optical emission of the moderately high redshift ($z=3.08$) GRB 060607A shows a remarkable broad and strong peak with a rapid rise and a relatively slow power-law decay. It is not coincident with the strong early-time flares seen in the X-ray and gamma-ray energy bands. There is weak evidence for variability superposed on this dominant component in several optical bands that can be related to flares in high energy bands. While for a small number of GRBs, well-sampled optical flares have been observed simultaneously with X-ray and gamma ray pulses, GRB 060607A is one of the few cases where the early optical emission shows no significant evidence for correlation with the prompt emission. In this work we first report in detail the broad band observations of this burst by Swift. Then by applying a simple model for the dynamics and the synchrotron radiation of a relativistic shock, we show that the dominant component of the early emissions in optical wavelengths has the same origin as the tail emission produced after the main gamma ray activity. The most plausible explanation for the peak in the optical light curve seems to be the cooling of the prompt after the main collisions, shifting the characteristic synchrotron frequency to the optical bands. It seems that the cooling process requires a steepening of the electron energy distribution and/or a break in this distribution at high energies. The sharp break in the X-ray light curve at few thousands of seconds after the trigger, is not observed in the IR/optical/UV bands, and therefore can not be a jet break. Either the X-ray break is due to a change in the spectrum of the accelerated electrons or the lack of an optical break is due to the presence of a related delayed response component (Abbreviated).
