D. B. Fox (PSU), J. R. Cummings (NASA/ORAU), N. Gehrels (NASA/GSFC), S. T. Holland (GSFC/USRA), S. D. Hunsberger (PSU), J. A. Kennea (PSU), H. A. Krimm (GSFC/USRA), C. B. Markwardt (GSFC/UMD), F. E. Marshall (NASA/GSFC), D. C. Morris (PSU), D. M. Palmer (LANL) and M. Stamatikos (NASA/GSFC/ORAU) report on behalf of the Swift Team:
At 02:11:18 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060522 (trigger=211117). Swift slewed immediately to the burst. The BAT on-board calculated location is RA,Dec 322.951, +2.876 {21h 31m 48s, +02d 52' 33"} (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). Since this was a 64-sec BAT image trigger, there is not enough information in the light curve at this time to describe the time profile of the burst. The peak count rate was ~500 counts/sec (15-350 keV), at ~5 sec after the trigger.
The XRT began taking data at 02:13:40 UT, 142 seconds after the BAT trigger. The XRT on-board centroid algorithm did not find a source in the image, however analysis of initial downlinked data shows the presence of an uncatalogued point source at the following coordinates: RA (J2000) = 21:31:44.9, Dec(J2000) = +02:53:08.5, with an error radius of 4.0 arcseconds (90% containment). This source is 61 arcseconds from the BAT position.
The UVOT began a 100 s white exposure at 02:13:47. A point source is detected in the XRT error circle with a white magnitude of 19.7. This source is not present in the DSS. The coordinates of this source are 21:31:44.8, +02:53:10 (J2000) with an uncertainty of +/- 0.6 arcsec (90% containment).

P. D'Avanzo (INAF/OAB), S. Piranomonte (INAF/OARm), A. Magazzu`, G. Mainella (INAF/TNG), report on behalf of a larger collaboration:
We observed the field of GRB 060522 (Fox et al. GCN 5150) with the 3.6m TNG telescope located in Canary Islands. One R-band image was obtained with TNG+DOLoRes, starting on May 22.1556 UT (about 1.5 hours after the burst) for a total exposure time of 10 minutes.
We see a bright object at the following position:
R.A.= 21:31:44.8, Dec +02:53:10.35 +/- 0.20 arcsec (J2000)
with a magnitude of R = 20.6 +/- 0.1 (vs USNO@ESO catalog)
We note that the position of this object is consistent with the UVOT afterglow candidate reported by Fox et al. (GCN 5150).
We thank the observing staff at TNG.

We imaged the field of GRB 060522 (Fox et al., GCN 5150) with the robotic 60-cm REM telescope located at La Silla (Chile) under mediocre weather conditions. A first set of observations was performed automatically in the near infrared (J, H, K, z bands) starting on May 22.2306 UT (about 3.3 hours after the burst). Then, we took a set of 20x100s H band images starting on May 22.2785 UT (about 4.5 hours the burst).
Preliminary analysis of both the datasets does not show any new source down to H = 16.5 and H=17.0 (3-sigma upper limits) respectively, at the position of the candidate optical afterglow reported by Fox et al. (GCN 5150) and D'Avanzo et al. (GCN 5151).

Palmer (LANL), A. Parsons (GSFC), T. Sakamoto (GSFC/ORAU), G. Sato (GSFC/JSPS/USRA), M. Stamatikos (GSFC/ORAU), J. Tueller (GSFC), on behalf of the Swift-BAT team:
Using the data set from T-239.0 to T+730.1 sec from the recent telemetry downlink, we report further analysis of BAT GRB 060522 (trigger #211117) (Fox, et al., GCN 5150). The BAT ground-calculated position is (RA,Dec) = 322.953, 2.889 deg {21h 31m 48.8s, 2d 53' 18.9"} (J2000) +- 1.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 75%.
The mask-weighted light curve shows two broad peaks, the first with a FRED-like profile from T+0 to T+20 sec and the second with a square profile from T+25 to T+80 sec. Nearly all emission is below 100 keV. T90 (15-350 keV) is 69 +- 5 sec (estimated error including systematics).
The time-averaged spectrum from T+0.2 to T+76.9 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.59 +- 0.15. The fluence in the 15-150 keV band is 1.1 +- 0.1 x 10^-06 erg/cm2. The 1-sec peak photon flux measured from T+4.41 sec in the 15-150 keV band is 0.6 +- 0.2 ph/cm2/sec. All the quoted errors are at the 90% confidence level.
GCN Circular #5154
J. A. Kennea, D. C. Morris and D. Fox (PSU) report on behalf of the Swift/XRT Team:
We have analysed the first 4 orbits of Swift/XRT data of GRB 060522 (Fox et al., GCN 5150) which equates to 4496+126 seconds of data. We find a refined XRT position for this burst of:
```
RA(J2000)  = 21:31:44.91
Dec(J2000) = +2:53:08.14
```
with an error of 3.7 arcseconds radius (90% containment). This position is 58 arcseconds from the refined BAT position quoted by Krimm et al. (GCN 5153), 0.4 arcseconds from the original XRT position from Fox et al., and 2.8 arcseconds from the optical counterpart reported by UVOT and confirmed by TNG (D'Avanzo et al., GCN 5151).
The afterglow shows several states: from T+150 to T+190 the lightcurve was bright (~6 XRT c/s) and relatively flat, at T+190 the lightcurve breaks and rapidly decays with a power-law slope of -4.0. The lightcurve breaks again at T+233s and flattens to a slope of -1.77. Centered at T+540 there is a small flare in the lightcurve. From T+1000s to T+5500s there is no data in the lightcurve, however the lightcurve appears to have flattened in this time. Data from T+5000 onwards shows the lightcurve is decaying with a slope of -1.3.
The average spectrum of the burst is well fit by an absorbed power-law model. The parameters of this fit are N_H = (4.6 +/- 2.5) x 10^20 cm^-2, and a power-law photon index of 1.97 +/- 0.21 (errors 90% confidence). The expected galactic absorption from this position in the sky is 4.83 x 10^20 cm^-2, so there is no evidence of excess absorption in this burst afterglow.
The prediction for the brightness of the burst 24 hours after the BAT trigger is approximately 2x10^-3 XRT Counts/s which is equivalent to a flux of ~7x10^-14 erg/s/cm^2 (0.2-10 keV).

S. B. Cenko (Caltech), E. Berger (Carnegie), S. G. Djorgovski, A. A. Mahabal (Caltech), and D. B. Fox (Penn State) report on behalf of a larger collaboration:
We have observed the location of the afterglow of GRB060522 (Fox et al., GCN 5150; D'Avanzo et al., GCN 5151) with the Low-Resolution Imaging Spectrometer mounted on the 10-m Keck I telescope. We obtained an 1800 s spectrum shortly before morning twilight at a mean epoch of May 22.65 UT (~ 12.5 hr after the burst).
We find a prominent absorption feature centered around ~ 7425 A, with a strong depression in flux blue-ward of this break. Identifying this as the Lyman-alpha break and fitting a DLA profile to the spectrum, we find z = 5.11 +/- 0.01 and log(nH) = 20.5 +/- 0.5.
At this redshift and using a 15-150 keV fluence of 1.1e-6 (Krimm et al., GCN 5153), we find the prompt emission isotropic energy release from GRB060522 is 5.1e52 ergs.

GRB 060522: Swift/UVOT Observations of the Optical Afterglow
S. T. Holland (NASA/GSFC & USRA) reports on behalf of the Swift/UVOT team:
The Swift UVOT began observing GRB 060522 (trigger #211117, Fox et al., GCN Circular 5150) 129 seconds after the BAT trigger. We detect the UVOT optical transient reported in the above Circular in the White filter. The J2000 coordinates of the afterglow are

  RA =  21:31:44.85
Dec = +02:31:44.9

with an uncertainty of +/- 0.6 arcseconds (90% containment).

These data are consistent with the burst having a redshift of z = 5.11 (Cenko et al., 2006, GCN Circular 5155). No correction has been made for the Galactic reddening of E(B-V) = 0.05 mag (Schlegel et al. 1998) along the line of sight to GRB 060522.

N. R. Tanvir et al.: Star formation in the early universe: beyond the tip of the iceberg
We present late-time Hubble Space Telescope imaging of the fields of six Swift GRBs lying at 5.090% confidence. Although it is not yet possible to make stronger statements, in the future, with larger samples and a fuller understanding of the conditions required for GRB production, studies like this hold great potential for probing the nature of star formation, the shape of the galaxy luminosity function, and the supply of ionizing photons in the early universe.
