  K. L. Page (U Leicester), S. D. Barthelmy (GSFC), A. P. Beardmore (U Leicester), J. R. Cummings (NASA/UMBC), V. D'Elia (ASDC), S. T. Holland (CRESST/USRA/GSFC), F. E. Marshall (NASA/GSFC), C. Pagani (U Leicester), D. M. Palmer (LANL), P. Romano (INAF-IASFPA), C. J. Saxton (UCL-MSSL), M. H. Siegel (PSU), M. C. Stroh (PSU) and T. N. Ukwatta (MSU) report on behalf of the Swift Team:
  At 21:08:28 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 110625A (trigger=456073). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 286.750, +6.753, which is

     RA(J2000)  =  19h 07m 00s
     Dec(J2000) = +06d 45' 10"
  

  with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows several bright peaks with a total duration of about 60 sec. The peak count rate was ~20,000 counts/sec (15-350 keV), at ~13 sec after the trigger.
  The XRT began observing the field at 21:10:48.8 UT, 140.3 seconds after the BAT trigger. Using promptly downlinked data we find a bright, fading, uncatalogued X-ray source located at RA, Dec 286.73189, 6.75386 which is equivalent to:

     RA(J2000)  = 19h 06m 55.65s
     Dec(J2000) = +06d 45' 13.9"
  

  with an uncertainty of 3.8 arcseconds (radius, 90% containment). This location is 64 arcseconds from the BAT onboard position, within the BAT error circle. This position may be improved as more data are received; the latest position is available at http://www.swift.ac.uk/sper.
  A power-law fit to a spectrum formed from promptly downlinked event data does not constrain the column density.
  The initial flux in the 2.5 s image was 1.72e-09 erg cm^-2 s^-1 (0.2-10 keV).
  UVOT took a finding chart exposure of 250 seconds with the U filter starting 205 seconds after the BAT trigger. No credible afterglow candidate has been found in the initial data products. The 2.7'x2.7' sub-image covers 100% of the XRT error circle. The typical 3-sigma upper limit has been about 19.2 mag. The 8'x8' region for the list of sources generated on-board covers 100% of the XRT error circle. The list of sources is typically complete to about 18.0 mag. No correction has been made for the large, but uncertain extinction expected.
  Burst Advocate for this burst is K. L. Page (kpa AT star.le.ac.uk). 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.)

  W. Zheng (U Mich) and W. Rujopakarn (Steward), report on behalf of the ROTSE collaboration:
  ROTSE-IIId, located at the Turkish National Observatory at Bakirlitepe, Turkey, responded to GRB 110625A (Swift trigger 456073; Page et al., GCN 12088), producing images beginning 6.8 s after the GCN notice time. An automated response took the first image at 21:08:48.8 UT, 20.3 s after the burst, and during the gamma-ray emission, under fair conditions. We took 10 5-sec, 10 20-sec and 110 60-sec exposures. These unfiltered images are calibrated relative to USNO A2.0 (R). Imaging is on going.
  Comparison to the DSS (second epoch) reveals no new sources within the 3-sigma Swift/BAT error circle or the XRT error circle, for both single images and coadding into sets of 10. Individual images have limiting magnitudes ranging from 15.5-16.6; we set the following specific limits.

Page (U Leicester), T. Sakamoto (GSFC/UMBC), M. Stamatikos (OSU), J. Tueller (GSFC), T. N. Ukwatta (MSU) (i.e. the Swift-BAT team):
  Using the data set from T-240 to T+602 sec from the recent telemetry downlink, we report further analysis of BAT GRB 110625A (trigger #456073) (Page, et al., GCN Circ. 12088). The BAT ground-calculated position is RA, Dec = 286.751, 6.755 deg, which is

     RA(J2000)  =  19h 07m 00.3s 
     Dec(J2000) = +06d 45' 17.8" 
  

  with an uncertainty of 1.3 arcmin, (radius, sys+stat, 90% containment). The partial coding was 5%.
  The mask-weighted light curve shows a series of peaks starting at ~T-12 sec, with major peaks at ~T-5, ~T+2, ~T+13 and ~T+18, followed by a long tail ending at ~T+350 sec. T90 (15-350 keV) is 44.5 +- 10.1 sec (estimated error including systematics).
  The time-averaged spectrum from T-6.2 to T+140.3 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.44 +- 0.04. The fluence in the 15-150 keV band is 2.8 +- 0.1 x 10^-5 erg/cm2. The 1-sec peak photon flux measured from T+13.74 sec in the 15-150 keV band is 49.5 +- 2.4 ph/cm2/sec. All the quoted errors are at the 90% confidence level.

  K. L. Page (U Leicester) reports on behalf of the Swift-XRT team:
  We have analysed 4.1 ks of XRT data for GRB 110625A (Page et al. GCN Circ. 12088), from 129 s to 34.9 ks after the BAT trigger. The data comprise 96 s in Windowed Timing (WT) mode (the first 10 s were taken while Swift was slewing) with the remainder in Photon Counting (PC) mode. The best available XRT position (using the promptly downlinked event data, the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue) is RA, Dec = 286.7327, 6.7553 which is equivalent to:

  RA (J2000): 19 06 55.85
  Dec(J2000): +06 45 19.2
  

  with an uncertainty of 2.1 arcsec (radius, 90% confidence).
  The light curve can be modelled with an initial power-law decay with an index of alpha=1.12 (+0.04, -0.03), followed by a break at T+18.7 ks to an alpha of 2.7 (+7.3, -1.2). There are insufficient data to constrain this steeper decay well at this time.
  A spectrum formed from the WT mode data can be fitted with an absorbed power-law with a photon spectral index of 2.5 (+/-0.4). The best-fitting absorption column is 6.3 (+1.1, -1.0) x 10^22 cm^-2, in excess of the Galactic value of 1.4 x 10^22 cm^-2 (Kalberla et al. 2005). The PC mode spectrum has a photon index of 1.8 (+/-0.4) and a best-fitting absorption column of 5.9 (+1.3, -1.1) x 10^22 cm^-2. The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 1.1 x 10^-10 (3.2 x 10^-10) erg cm^-2 count^-1.
  A summary of the PC-mode spectrum is thus:

  Total column:	     5.9 (+1.3, -1.1) x 10^22 cm^-2
  Galactic foreground: 1.4 x 10^22 cm^-2
  Excess significance: 8.7 sigma
  Photon index:	     1.8 (+/-0.4)

  The long bright GRB 110625A (Swift-BAT trigger #456073: Page et al., GCN 12088; Palmer et al., GCN 12091) triggered Konus-Wind at T0=3D76105.088s UT (21:08:25.088)
  The burst light curve consists of several multi-peaked pulses, a total duration of the burst is ~60 s. The emission is seen up to ~8 MeV. The Konus-Wind light curve of this GRB is available at http://www.ioffe.ru/LEA/GRBs/GRB110625_T76105/
  As observed by Konus-Wind the burst had a fluence of (6.1 =B1 0.6)x10-5 erg/cm2, and a 64-ms peak flux, measured from T0+20.992 s, of (1.5 =B1 0.2)x10-5 erg/cm2/s (both in the 20 keV - 10 MeV energy range).
  The time-integrated spectrum of the burst (from T0 to T0+58.880 s) is best fitted in the 20 keV - 10 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -1.05 (-0.08, +0.08), the high energy photon index beta = -2.7 (-0.5, +0.2), the peak energy Ep = 190(-14, +17) keV, chi2 = 79.7/87 dof.
  The spectrum at the maximum count rate (measured from T0+20.992 to T0+21.504 s) is best fitted in the 20 keV - 10 MeV range by the GRB (Band) model, for which: the low-energy photon index alpha = -0.8 (-0.2, +0.2), the high energy photon index beta = -2.5 (-0.5, +0.2), the peak energy Ep =3D 168(-24, +40) keV, chi2 = 45.2/46 dof.
  All the quoted results are preliminary. All the quoted errors are at the 90% confidence level.

  We observed the field of GRB 110625A (trigger=456073) using the Swift-XRT position provided by K.L. Page et al. (GCN 12088) with a 60/90 cm Schmidt telescope located at the Mountain Station of the Konkoly Observatory. We coadded 4 CCD images with 300 sec exposure time each. After checking the coadded frame we did not find any OT brighter than 21.5 mag in R the band within the XRT error circle. The photometry based on UCAC-3 stars around the field.

  We observed GRB 110625A (Page et al. GCN 12088) in zYHK filters with UKIRT starting at 2011 June 26,10:08:47 UT. Within the enhanced XRT error circle (Page et al. GCN 12092), we detect a NIR source in all the filters, whose coordinate is
  RA=19:06:55.8, Dec=06:45:19.2
  with positional error of ~0.5". K-band magnitude is found to be about 17.5 mag, calibrated against a 2MASS star at (19:06:55.65, 06:45:16.2)
  The variability of the source is being examined with additional data.
• GCN Circular #12096
  R. Filgas (MPE Garching), A. Rossi, A.D. Kann (both TLS Tautenburg), A. Rau and J. Greiner (both MPE Garching) report on behalf of the GROND team:
  We observed the field of GRB 110625A (Swift trigger 456073; Page et al., GCN #12088) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPI/ESO telescope at La Silla Observatory (Chile).
  Observations started at 02:24 UT on June 26, 5.3 hours after the GRB trigger, continued until 03:11 UT, and were obtained at high airmass. A second epoch was obtained starting at 05:35, 8.46 hours after the burst, and finished at 07:06 UT.
  Inside the refined XRT error circle (Page et al., GCN #12092) we found a single source at
  RA,DEC (J2000)= 19:06:55.89, +06:45:19.5
  (+-0.3"), consistent with the source reported by Im at al., GCN #12095. Over the course of 5 hrs, no variability is detected in relative photometry measured against a field star at RA,DEC(J200)=19:06:56.99,+06:45:20.4 with z_AB = 19.4 mag.
  We measure the following magnitudes (all in AB) from the first 1440s and 1200s of exposure in g'r'i'z' and JHK, respectively:

  g' > 24.3
  r' = 24.1 +/- 0.2
  i' = 22.6 +/- 0.1
  z' = 21.5 +/- 0.1
  J =  21.1 +/- 0.7
  H > 18.6
  K > 17.8
  

  The photometry were derived by calibration against GROND zeropoints and 2MASS field stars and are not corrected for the Galactic foreground extinction corresponding to a reddening of E_(B-V) ~ 10.5 mag in the direction of the burst (Schlegel et al. 1998).
  Given the lack of variability and a color much bluer than would be expected according to the strong foreground extinction, we suggest that this optical/near-IR source is likely a Galactic object unrelated to GRB 110625A.
• GCN Circular #12097
  P.H.T. Tam and A.K.H. Kong (NTHU) report:
  We report on the detection of >100 MeV gamma-ray emission from the direction of GRB 110625A (Swift trigger 456073; Page et al., GCN #12088) using the Fermi Large Area Telescope (LAT).
  The GRB position was outside the LAT field of view (i.e., >75 deg with respect to the LAT boresight) at the burst onset (T0; 2011-06-25 UT 21:08:28; GCN #12088). However, prominent emission up to several GeV was detected from the GRB direction around T0+200s to T0+500s, during which the light curve seems to resemble a double-peak structure. Using the data obtained from the above period, we localized the LAT emission at RA, DEC (J2000 deg) = 286.6, 6.9, with a statistical error of ~0.3 deg (68% CL), which is compatible with the refined Swift/XRT position (Page et al., GCN #12092). A preliminary spectral fit gives a photon spectral index of around -3 at energies above 100 MeV.

  J. Gorosabel (IAA-CSIC), V. Terron (IAA-CSIC), P. Ferrero (IAC), M. Jelinek (IAA-CSIC), P. Kubanek (IAA-CSIC & U. Valencia), M. Fernandez (IAA-CSIC), report on behalf of a larger collaboration:
  "We observed the field of GRB 110625A (Page et al., GCN 12088) with the 1.23m telescope of Calar Alto observatory. We obtained 45x60s I-band images on July 25.88457--25.93027 UT (i.e, starting 5.32 min after the trigger).
  In the co-added image, we detect a source at RA(J2000)=19:06:55.88, DEC(J200)=06:45:19.4 (+/-0.5") which is consistent with the objects reported by Im et al. (GCN 12095) and Filgas et al. (GCN 12096). Using as photometric reference the USNO B1.0 star located at RA(J2000) = 19:06:56.17, DEC(J2000)=06:44:25.9 with I=16.56, we derived a preliminary magnitude of I=20.6 (Vega system) for the object inside the XRT error circle.
  This magnitude might indicate some degree of fading with respect to the i-band AB mag reported by Filgas et al. (GCN 12096). However, we are still cautious on the possible association of this object with the GRB.
  Further multi-band observations are encouraged."

• GCN Circular #12100
  David Gruber (MPE), Nicola Omodei (Stanford U.), Vandiver Chaplin (UAH), J. Chiang (KIPAC/SLAC), J. McEnery (NASA/GSFC), J. L. Racusin (NASA/GSFC) report on behalf of the Fermi GBM and LAT Teams:
  At 21:08:18.24 UT on 25 June 2011, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 110625A (trigger 330728900 / 110625881), which was also detected by the Swift/BAT (Page et al. 2011, GCN 12088). The GBM on-ground location is consistent with the Swift position.
  The angle from the Fermi LAT boresight is 88 degrees at the trigger time. Moreover, this burst was bright enough to result in a Fermi spacecraft autonomous rapid repoint (ARR) maneuver.
  This burst was also independently detected by INTEGRAL SPI-ACS.
  The GBM light curve shows several pulses with a duration (T90) of about 27.7 +/- 1.4 s (50-300 keV). The time-averaged spectrum from T0-2.048 s to T0+60.417 s is best fit by a power law function with an exponential high-energy cutoff. The power law index is -0.95 +/- 0.01 and the cutoff energy, parameterized as Epeak, is 209 +/- 3 keV.
  The event fluence (10-1000 keV) in this time interval is (6.71 +/- 0.02)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+23.9 s in the 10-1000 keV band is 77.3 +/- 0.7 ph/s/cm^2.
  A Band function fits the spectrum equally well with Epeak= 175 +/- 5 keV, alpha = -0.85 +/- 0.02 and beta = -2.37 +/- 0.05.
  The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog.
  The ARR maneuver put the GRB inside the Fermi/LAT field of view for several hundred seconds (from ~100-600 seconds after the GBM trigger).
  The Spacecraft continued its maneuver toward the Fermi GBM flight software reconstructed position, that was off by 68 degrees from the Enhanced Swift/XRT position (GCN 12092), providing non-optimal exposure for LAT follow-up observations.
  We analyzed the LAT data and we see significant high-energy emission from a point source coincident with the XRT position, confirming the already reported results by P.H.T. Tam and A.K.H. Kong (GCN 12097).
  We model the source spectrum with a power law model N(e) = N0 e^{\beta}, and the background including both the contribution from the Galactic diffuse emission and the isotropic contribution due to the residual contamination of charged particles.
  We detect the GRB in two distinct time periods. In the first time bin (from 237.1 seconds to 316.2 seconds after the GBM trigger), we measure a flux (100 MeV-10 GeV) of (4.9 +/- 1.9) x 1e-05 ph/cm^2/s and a spectral index beta of -2.1 +/- 0.3, with a Test Statistic TS=31.
  In the second time bin, from 421.7 to 562.3 seconds after the GBM trigger, the measured flux is (3.7 +/- 1.5) x 1e-5 ph/cm^2/s with spectral index beta of -3.6 +/- 0.8 and a TS=19 (stat errors only).
  The Fermi LAT point of contact for this burst is Nicola Omodei (nicola.omodei@gmail.com).
  The Fermi LAT is a pair conversion telescope designed to cover the energy band from 20 MeV to greater than 300 GeV. It is the product of an international collaboration between NASA and DOE in the U.S. and many scientific institutions across France, Italy, Japan and Sweden.

  triggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV at 2011-06-25 21:08:22.01 UT (=T0).
  The observed light curve shows a multi-peaked structure (starting at T0-1s, ending at T0+28s) with a duration (T90) of about 24 seconds. The fluence in 100 - 1000 keV was 2.54 (+/-0.09) x 10^-05 erg/cm^2.
  The 1-s peak flux measured from T0+20s was 13.6 (+/-1.0) photons/cm^2/s in the same energy range.
  Preliminary result shows that the time-averaged spectrum from T0-1s to T0+28s is well fitted by a single power-law with a photon index of 2.26 (+/- 0.09) (chi^2/d.o.f = 31.7/24).
  However, there might be some calibration uncertainties in the flux value because GRB photons came to the WAM detector by passing through the large Ne dewar of the X-ray micro-calorimeter (XRS).
  All the quoted errors are at statistical 90% confidence level, in which the systematic uncertainties are not included.

  P. H. Thomas Tam et al.: Fermi Large Area Telescope observations of GRB 110625A
  Gamma-ray bursts (GRBs) that emit photons at GeV energies form a small but significant population of GRBs. However, the number of GRBs whose GeV-emitting period is simultaneously observed in X-rays remains small. We report gamma-ray observations of GRB 110625A using Fermi's Large Area Telescope (LAT) in the energy range 100 MeV to 20 GeV. Gamma-ray emission at these energies was clearly detected using data taken between 180s and 580s after the burst, an epoch after the prompt emission phase. The GeV light curve differs from a simple power-law decay, and probably consists of two emission periods. Simultaneous Swift/XRT observations did not show flaring behaviors as in the case of GRB 100728A. We discuss the possibility that the GeV emission is the synchrotron self-Compton radiation of underlying ultraviolet flares.
