  W. Rujopakarn (Steward), E.S. Rykoff (UCSB), report on behalf of the ROTSE collaboration:
  ROTSE-IIIb, located at McDonald Observatory, Texas, responded to GRB 080607 (Swift trigger 313417). The first image was at 06:07:49.0 UT, 22.0 s after the burst (6.0 s after the GCN notice time). The unfiltered images are calibrated relative to USNO A2.0. We detect a 14.8 magnitude, fading source with coordinates:
  12:59:47.3 +15:55:10.8 (J2000), with positional uncertainty of 1" or better

  start UT    	mag     mlim(of image)
  ----------------------------------
  06:07:49.0     14.8     16.4
  

  This source is not visible in DSS (second epoch), 2MASS or the MPChecker database.
  A jpeg image is available at http://www.rotse.net/images/gsb313417_3b00_img.jpg Note that the object marked 11 is the candidate in question.
  Continuing observations are in progress.

• GCN Circular #7847
  V. Mangano (INAF-IASFPA), J. R. Cummings (NASA/UMBC), G. Cusumano (INAF-IASFPA), N. Gehrels (NASA/GSFC), V. La Parola (INAF-IASFPA), C. B. Markwardt (CRESST/GSFC/UMD), J. P. Osborne (U Leicester), B. Sbarufatti (INAF-IASFPA) and D. E. Vanden Berk (PSU) report on behalf of the Swift Team:
  At 06:07:27 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 080607 (trigger=313417). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 194.967, +15.900 which is

     RA(J2000) = 12h 59m 52s
     Dec(J2000) = +15d 54' 01"
  

  with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve showed a multi-peak structure with a duration of about 80 sec. The peak count rate was ~35000 counts/sec (15-350 keV), at ~2 sec after the trigger.
  The XRT began observing the field at 06:08:49.1 UT, 82.1 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 194.9462, +15.9208 which is equivalent to:

     RA(J2000)  = 12h 59m 47.0s
     Dec(J2000) = +15d 55' 14.8"
  

  with an uncertainty of 5.0 arcseconds (radius, 90% containment). This location is 103 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy.
  UVOT took a finding chart exposure of 100 seconds with the White (160-650 nm) filter starting 92 seconds after the BAT trigger. There is a candidate afterglow in the rapidly available 2.7'x2.7' sub-image at

    RA(J2000)  =	12:59:47.21 = 194.9467
    DEC(J2000) = +15:55:10.9  =  15.9197
  

  with a 1-sigma error radius of about 0.5 arc sec. This position is 4.9 arc sec. from the center of the XRT error circle. The estimated magnitude is 19.7 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 0.02.
  Burst Advocate for this burst is V. Mangano (vanessa AT ifc.inaf.it). 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.)

  Adria C. Updike (Clemson University), Peter A. Milne (Steward Observatory), and G. Grant Williams (MMTO) report:
  Super-LOTIS began observing GRB 080607 35 second after the trigger (313417). We detect the fading source reported by Rujopakarn et al. (GCN 7846) at R = 15.2 +/- 0.05 mag (as compared to a nearby star in the USNO B1.0 catalog) 40 seconds after the trigger. Observations are continuing.

  J. X. Prochaska (UCO/Lick), J. Shiode, J. S. Bloom, D. A. Perley, A. A. Miller, J. Shiode, D. Starr, R. Kennedy, and J. Brewer (UC Berkeley) report:
  Upon receiving the GCN alert we immediately slewed with Keck I (+LRIS) to the field of GRB 080607 (GCN 7847, Mangano et al.). The optical transient (GCN 7846, Rujopakarn et al.) was visually identified on the guider. Spectroscopic observations began at 06:20:35 UT, 13 minutes after the trigger, using the 600 and 400 line gratings on the blue and red cameras, respectively, for wavelength coverage between 3000-9300 A.
  Our preliminary reduction of the LRIS-b spectrum reveals a very strong, damped Lya profile and metal-line transitions of OI, SiII, CII, SiII* among others. These establish the redshift of the GRB to be z=3.036.
• GCN Circular #7850
  A. A. Miller, J. S. Bloom, D. A. Perley (UC Berkeley), D. Starr (UCB, LCOGT) report:
  We observed the optical afterglow of GRB 080607 (Mangano et al., GCN 7847, Rujopakarn et al., GCN 7846) with the 1.3m Peters Automated Infrared Imaging Telescope (PAIRITEL). Observations began at 06:08:44 Jun 07, 2008 UT. We detect the afterglow in a 612 sec mosaic of 7.8 sec simultaneous exposures in the J, H, and Ks filters. Preliminary photometry for the afterglow in exposures beginning on 06:10:32 Jun 07, 2008 UT yields J = 17.1 +- 0.1, H = 15.3 +- 0.1, and Ks = 13.7 +- 0.1, calibrated to the 2MASS system.

  Using the data set from T-240 to T+302 sec from recent telemetry downlinks, we report further analysis of BAT GRB 080607 (trigger #313417) (Mangano, et al., GCN Circ. 7847). The BAT ground-calculated position is RA, Dec = 194.964, 15.910 deg, which is

     RA(J2000)  =  12h 59m 51.4s 
     Dec(J2000) = +15d 54' 37.6" 
  

  with an uncertainty of 1.0 arcmin, (radius, sys+stat, 90% containment). The partial coding was 11%.
  The mask-weighted light curve shows multiple peaks. The first starts at ~T-5 sec. The main cluster of overlapping peaks starts at ~T-1 sec, with the brightest peak at T+2.0 sec, and ending at ~T+10 sec. Following that is a series of weak peaks out to ~T+180 sec. T90 (15-350 keV) is 79 +- 5 sec (estimated error including systematics).
  The time-averaged spectrum from T-5.9 to T+154.7 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.31 +- 0.04. The fluence in the 15-150 keV band is 2.4 +- 0.0 x 10^-05 erg/cm2. The 1-sec peak photon flux measured from T+1.50 sec in the 15-150 keV band is 23.1 +- 1.1 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

  J.P. Osborne, A.P. Beardmore, P.A. Evans and M.R. Goad (U. Leicester) report on behalf of the Swift-XRT team.
  Using 818 s of overlapping XRT Photon Counting mode and UVOT data for GRB 080607, 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 = 194.94644, +15.91935 which is equivalent to:

  RA (J2000): 12h 59m 47.15s
  Dec (J2000): +15d 55' 09.7"
  

  with an uncertainty of 1.7 arcsec (radius, 90% confidence).

  The Katzman Automatic Imaging Telescope (KAIT) at Lick Observatory responded to the Swift alert for GRB 080607 (Mangano et al., GCN 7847) and detected the optical afterglow previously announced by several other teams (Rujopakarn et al., GCN 7846; Mangano et al., GCN 7847; Updike et al., GCN 7848; Prochaska et al., GCN 7849; Miller et al., GCN 7850).
  KAIT took a series of V, I, and unfiltered images starting at 06:09:25 (UT), 118s after the BAT trigger. The KAIT position is:

  P. Schady (MSSL/UCL) and V. Mangano (INAF-IASFPA) report on behalf of the Swift UVOT team
  The Swift UltraViolet/Optical Telescope (UVOT) began taking settled observations of GRB 080607 92 seconds after the initial Swift BAT trigger (Mangano et al., GCN Circ. 7847). A faint afterglow is detected in the first white and v-band finding chart exposures only at the refined uvot position of RA=194.94665, Dec=+15.91965 deg.(= 12:59:47.20 +15:55:10.74), with an accuracy of 0.5". This is consistent with the GRB being at a redshift of z=3.036, as reported in GCN Circ. 7849 (Prochaska et al.)
  The first white and v-band finding chart magnitudes with 1-sigma errors are given below, as well as the 3-sigma upper limits for co-added images from later observations.

• GCN Circular #7859
  B. Sbarufatti, V. Mangano, V. La Parola (INAF-IASF Pa) report on behalf of the Swift-XRT team.
  Swift-XRT began observations of the field of GRB 080607 (trigger 313417, Mangano et al., GCN circ. 7847) on date 2008 June 07, 06:08:54 UT, 87 s after the BAT trigger. The data consist of 478 s in Windowed timing mode and 3 ks in Photon Counting mode.
  The lightcurve shows a complex behaviour. After an initial steep decay (index 5.8 +/- 0.4) we observe a double peaked flare, starting at T+ 118 (+/- 1) s and peaking at T+120 s and T+140 s. The underlying decay breaks at T+ 119 (+ 5, - 2) s to a slope of 1.7 (+/- 0.1). A second break at t+700 (+/- 300) marks the beginning of a plateau phase (index 0.5 +/- 1.3). The lightcurve breaks again around T+1600 (+/- 500) s, with a final decay index of -2.0 +/- 0.5. The countrate predictions for T+24h and T+48h are 2.1E-3 counts/s and 5.5E-4 count/s respectively.
  The WT spectrum can be fit by a powerlaw with photon index 1.81 +/- 0.02 and an intrinsic absorbing column density of (4.0 +/- 0.2)E22 cm^-2 at z=3.036 (Prochaska et al. GCN Circ. 7849), in excess with respect to the Galactic value of 1.69E+20 cm^-2 (Kalberla et al. 2005). The observed (unabsorbed) flux in the 0.3 - 10 keV band is 2.9 (3.0)E-9 erg cm^-2 s^-1. The PC spectrum can be fit by a powerlaw with photon index 2.1 +/- 0.1 and an intrinsic absorbing column density of (4.0 +/- 0.8)E21 cm^-2 at z=3.036, in excess with respect to the Galactic value. The observed (unabsorbed) flux in the 0.3 - 10 keV band is 5.3 (5.4)E-11 erg cm^-2 s^-1.

  S. Golenetskii, R.Aptekar, E. Mazets, V. Pal'shin, D. Frederiks, P. Oleynik, M. Ulanov, D. Svinkin, and T. Cline on behalf of the Konus-Wind team report:
  The bright GRB 080607 (Swift-BAT trigger #313417: Mangano et al., GCN 7847, Stamatikos et al., GCN 7852) triggered Konus-Wind at T0=22043.336 s UT (06:07:23.336).
  The burst light curve consists of the main part, which shows a multipeaked structure with a duration of ~16 s, and the extended emission, which shows many weak pulses up to ~T0+85 s in the soft energy band (~18-70 keV).
  As observed by Konus-Wind the burst had a fluence of 8.93(-0.47, +0.52)x10^-5 erg/cm2, and a 16-ms peak flux measured from T0+7.168 s of (2.69 +/- 0.54)x10^-5 erg/cm2/s (both in the 20 keV - 4 MeV energy range).
  The time-integrated spectrum of the burst (from T0 to T0+84.48 s) can be fitted (in the 20 keV - 4 MeV range) by a power law with exponential cutoff model: dN/dE ~ (E^alpha)*exp(-E*(2+alpha)/Ep) with alpha = -1.08(-0.06, +0.07), and Ep = 419(-38, +46) keV (chi2 = 78.8/73 dof). Fitting by GRBM (Band) model yields: the low-energy photon index is alpha = -1.06(-0.08, +0.09), the high energy photon index beta < -2.28, the peak energy Ep = 394(-54, +58) keV (chi2 = 77.2/72 dof).
  The spectrum of the main part (from T0 to T0+18.944 s) can be fitted (in the 20 keV - 4 MeV range) by GRBM (Band) model for which: the low-energy photon index is alpha = -0.76(-0.06, +0.07), the high energy photon index beta = -2.57(-0.26, +0.18), the peak energy Ep = (348 +/- 27) keV (chi2 = 99.6/72 dof). The fluence of this part is (8.59 +/- 0.40)x10^-5 erg/cm2.
  All the quoted errors are at the 90% confidence level.
  Assuming z = 3.036 (Prochaska et al., GCN 7849) and a standard cosmology model with H_0 = 70 km/s/Mpc, Omega_M = 0.27, Omega_\Lambda = 0.73, the isotropic energy release is E_iso = 1.87(-0.10, +0.11)x10^54 erg, the peak luminosity is (L_iso)_max = (2.27 +/- 0.46)x10^54 erg/s, and Ep_rest ~1600 keV. This isotropic energy release is one of the largest ever measured (the current record holder is GRB 990123 for which the isotropic energy release is ~2.8x10^54 erg), and this peak luminosity is the highest ever reported.

  "The Swift localized GRB 080607 (Mangano et al., GCN 7847; Stamatikos et al., GCN 7852) triggered the Mini-Calorimeter (MCAL) instrument onboard the AGILE satellite at 06:07:23 UT (=T0). The MCAL instrument covers the energy range 350 keV - 10 MeV, without imaging capabilities.
  Using the preliminary in-flight calibration and assuming a Crab-like spectrum, we can estimate the fluence in the 350-700 keV energy band to be (23 +/- 7) photons/cm2 corresponding to (1.8 +/- 0.5)x10^-5 erg/cm2, in the time interval T0-T0+14 s. The 1-s peak flux measured at T0+5.1 s is (4.2 +/- 1.2) photons/cm2/s in the same energy band. The GRB was detected also in the 1.4-2.8 MeV energy band with a 10 sigma significance in the 256-ms time window.
  We note that the quoted fluence is in agreement within errors with that obtained using the Konus-Wind spectrum reported in Golenetskii et al., GCN 7862. Assuming the spectral model reported in GCN 7862, an agreement in flux within 10% for the energy band 350-700 keV is obtained.
  The Swift localization is at about 113 degrees off-axis with respect to the AGILE pointing, so well out of the field of view of the AGILE Gamma-Ray Imaging Detector (GRID), sensitive in the 50 MeV - 50 GeV energy range. Analysis of the GRID count rate does not show any detection.
  This GRB triggered also SuperAGILE and was detected at about 17 sigma significance level in the 18-60 keV band, although it was well outside the field of view, and was detected through the collimator shielding."

• 1205.0387 from 3 May 12
  Tayyaba Zafar et al.: The properties of the 2175AA extinction feature discovered in GRB afterglows
  Giorgos Leloudas (1), Pall Jakobsson (4), Christina C. Thone (5), Daniel A. Perley (6), Adam N. Morgan (6), Joshua Bloom (6), Jochen Greiner (3) ((1) DARK, (2) LAM, (3) MPI, (4) Univ. of Iceland (5) Univ. of California) The unequivocal, spectroscopic detection of the 2175 bump in extinction curves outside the Local Group is rare. To date, the properties of the bump have been examined in only two GRB afterglows (GRB 070802 and GRB 080607). In this work we analyse in detail the detections of the 2175 extinction bump in the optical spectra of the two further GRB afterglows: GRB 080605 and 080805. We gather all available optical/NIR photometric, spectroscopic and X-ray data to construct multi-epoch SEDs for both GRB afterglows. We fit the SEDs with the Fitzpatrick & Massa (1990) model with a single or broken PL. We also fit a sample of 38 GRB afterglows, known to prefer a SMC-type extinction curve, with the same model. We find that the SEDs of GRB 080605 and GRB 080805 at two epochs are fit well with a single PL with a derived extinction of A_V = 0.52(+0.13 -0.16) and 0.50 (+0.13 -0.10), and 2.1(+0.7-0.6) and 1.5+/-0.2 respectively. While the slope of the extinction curve of GRB 080805 is not well-constrained, the extinction curve of GRB 080605 has an unusual very steep far-UV rise together with the 2175 bump. Such an extinction curve has previously been found in only a small handful of sightlines in the MW. One possible explanation of such an extinction curve may be dust arising from two different regions with two separate grain populations, however we cannot distinguish the origin of the curve. We finally compare the four 2175 bump sightlines to the larger GRB afterglow sample and to Local Group sightlines. We find that while the width and central positions of the bumps are consistent with what is observed in the Local Group, the relative strength of the detected bump (A_bump) for GRB afterglows is weaker for a given A_V than for almost any Local Group sightline. Such dilution of the bump strength may offer tentative support to a dual dust-population scenario.
