  J. L. Racusin (PSU), S. D. Barthelmy (GSFC), D. N. Burrows (PSU), M. M. Chester (PSU), N. Gehrels (NASA/GSFC), H. A. Krimm (GSFC/USRA), D. M. Palmer (LANL) and T. Sakamoto (NASA/ORAU) report on behalf of the Swift Team:
  At 04:59:29 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 070714 (trigger=284856). Swift slewed immediately to the burst. The BAT on-board calculated location is RA, Dec 57.854, +28.295 which is

     RA(J2000)  =  03h 51m 25s
     Dec(J2000) = +28d 17' 43"
  

  with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a duration of 3 seconds with a spike to a peak of 20000 counts/s (15-350 keV) at T+0.2 s.
  The XRT began observing the field at 05:00:30 UT, 61 seconds after the BAT trigger. Using ground processed data, XRT found a bright, fading, uncatalogued X-ray source located at RA, Dec 57.8423, +28.2978 which is

     RA(J2000)  =  03h 51m 22.1s
     Dec(J2000) =  28d 17' 52.0"
  

  with an uncertainty of 3.9 arcseconds (radius, 90% containment). This location is 39 arcseconds from the BAT on-board position, within the BAT error circle. The initial flux in the 2.5s image was 2.4e-09 erg/cm2/s (0.2-10 keV).
  The UVOT began observing the field at 05:00:40.05 UT, 70.4 s after the BAT trigger. No counterpart is apparent in the 2.7' x 2.7' subimage, based on visual comparison with the DSS. Additional processing is underway.

  A. Melandri (Liverpool JMU) on behalf of the Liverpool GRB team report:
  On 2007 Jul 14 at 05:10:56 UT the 2-m Liverpool Telescope automatically observed the field of GRB 070714 (trigger=284856, Racusin et al. GCN 6620).
  Due to the incoming dawn the automatic observation sequence stopped after ~15 minutes, after the acquisition of only 9 frames.
  Inside the XRT error circle (Racusin et al. GCN 6620) we find a single source at the position (error of 0.5 arcsec)

  RA = 03:51:22.2
  Dec = +28:17:51.4
  

  It is not a catalog source but presently it's not clear yet whether the object is fading.

  Using the data set from T-120 to T+182 sec from recent telemetry downlinks, we report further analysis of BAT GRB 070714B (trigger #284856) (Racusin, et al., GCN Circ. 6620). The BAT ground-calculated position is RA, Dec = 57.853, 28.294 deg which is

     RA(J2000)  =  3h 51m 24.8s
     Dec(J2000) = 28d 17' 37"
  

  with an uncertainty of 1.4 arcmin, (radius, sys+stat, 90% containment). The partial coding was 93%.
  The BAT mask-weighted light curve shows multiple short spikes starting from T-0.8 sec with a duration of 3 sec. There is extended softer emission from T+20 sec to T+70 (and possibly T+100) sec. T90 (15-350 keV) is 64 +- 5 sec (estimated error including systematics). The light curve looks similar to previous short bursts such as GRB 050724 with a short-hard initial episode followed by a softer extended episode, so we think it is likely that this burst is in the short category.
  The time-averaged spectrum from T-0.8 to T+65.6 sec is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.36 +- 0.19. The fluence in the 15-150 keV band is 7.2 +- 0.9 x 10^-7 erg/cm2. The 1-sec peak photon flux measured from T-0.39 sec in the 15-150 keV band is 2.7 +- 0.2 ph/cm2/sec. Separating out the initial "spike" of emission (from T-0.8 to T+2 sec), the photon index in a simple power-law fit is 0.99 +- 0.08. The fluence in the 15-150 keV band of this part is 5.1 +-0.3 x 10^-7 erg/cm2. All the quoted errors are at the 90% confidence level.

  "We clarify that the imaging information reported in the circular GCN 6624 (Nugent & Bloom) refers to GRB 070714b (short-hard burst; Barbier et al. 6623; trigger #284856) and not GRB 070714a (short and XRF-like; Barthelmy et al. 6622; trigger #284850). We apologize for any confusion and thank S. Barthlemy for alerting us to the citation error in the previous circular.

  GRB 070714b ("Bastille"): Optical Pre-Imaging
  P. Nugent (LBL) and J. S. Bloom (UC Berkeley) report:
  "We have created a stacked image through the co-addition of 8 unfiltered images taken by the NEAT collaboration and 51 images in the RG610 filter taken by the Palomar-Quest Consortium at the Palomar Oschin Schmidt telescope (obtained from 2002-2006), of what is being called a short-hard burst (SHB) 070714B (Barbier et al.; GCN #6623). The stacked image is significantly deeper than the DSS (3 sigma limit of R~22.7 mag). There is no source at the position of the proposed counterpart (Melandri et al. GCN #6621). Since this Liverpool Telescope source was detected in twilight, it was likely seen near the DSS limit (or brighter) and thus, while we cannot say for sure (since no magnitude was given in GCN #6621), the absence of a similarly bright source in our image suggests that the Melandri et al. source was indeed the afterglow.
  Note that the source @ position RA = 03:51:21.24, DEC = +28:17:45.5 is in the 2MASS catalog and is blue (J - K = 0.5 mag).

  J. Racusin, J. Kennea, C. Pagani, L. Vetere (PSU), and P. Evans (U. Leicester) report on behalf of the Swift/XRT team:
  We have analyzed the first 15 ks of Swift XRT PC and WT data from GRB 070714B (Racusin et al., GCN 6620). Using 770 s of overlapping XRT Photon Counting mode and UVOT V-band data, 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 = 57.84287, 28.29782 which is equivalent to:

  RA (J2000):  03h 51m 22.29s
  Dec (J2000): +28d 17' 52.2"
  

  with an uncertainty of 1.8 arcsec (90% confidence, radius). This is 35 arcsec from the refined BAT position (Barbier et al., GCN 6623), and 1.4 arcsec from the Liverpool optical afterglow candidate (Melandri et al., GCN 6621).
  The XRT light curve shows a fading behavior with super-imposed small flaring. The light curve can be fit with a power-law beginning with a steep decay with a slope of 2.49 +/- 0.18 followed by a plateau beginning at 413s +/- 50s with a slope of 0.60 +/- 0.29 until another break at 1187 +/- 270s with a decay of 1.73 +/- 0.11.
  The X-ray PC and WT spectrum is well fit by an absorbed power law with a photon index for 1.2 +/- 0.1 and a column density of 13 +/- 3 e20 cm^-2 in excess of the galactic value (6.4e20 cm-2). The absorbed (unabsorbed) 0.3-10.0 keV flux of the WT spectrum is 9.2e-10 (1.0e-9) erg cm^-2s^-1 and the flux of the PC spectrum is 3.4e-12 (3.7e-12) ergs cm^-2 s^-1.
  Assuming the source continues to decay at the same rate, we predict an XRT count rate of 2.7e-4 counts/s at T0+24 hours, which corresponds to an observed (unabsorbed) flux of 1.8e-13 (2.0e-13) ergs cm^-2 s^-1.

  We imaged the field of GRB 070714B (Racusin et al. GCNC 6620) with the William Herschel Telescope (WHT), obtaining at total of 2700s of observations in the R-band, beginning on July 15 04:17 UT. At the position of the afterglow candidate of Melandri (GCNC 6621), we detect an object with a magnitude of R~23.5 (relative to two USNO stars within the field). The observed fading confirms the association with GRB 070714B. Further observations will be necessary to determine if the current magnitude is significantly contaminated by an underlying host galaxy.

  J. Norris (Stanford U), S.D. Barthelmy (GSFC), T. Ukwatta (GWU) on behalf of the Swift-BAT team:
  Using the event-by-event data from Swift-BAT, the spectral lag for GRB 070714B (Racusin, et al., 6620; Barbier, et al., 6623) is:

       9 ms +- 4 ms   (100-350 to 25-50 keV)
      14 ms +- 7 ms   ( 50-100 to 15-25 KeV)
  

  using 4-msec binning (for the 2.9-sec interval covering the initial spike). This is consistent with "zero lag" for short hard bursts.

  The Swift/UVOT observed the field of GRB 070714B starting 70 s after the BAT trigger (Racusin et al. GCN Circ.6620).

  The short GRB 070714B (Swift/BAT trigger #284856; Racusin et al., GCN 6620; Barbier et al., GCN 6623) triggered the Suzaku Wide-band=20 All-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV at 04:59:29.247 UT (=3DT0). The observed light curve with 1/64 sec resolution shows a multi-peaked structure with a sharp strong peak at ~T0+0.45 sec. The duration (T90)=20 was about 2.0 sec. The fluence in 100 - 1000 keV was (2.3 =B1 0.2)x10^-6 erg/cm^2, while the 1-s peak flux measured from T0+0 to T0+1 sec was 2.8 =B1 0.3 photons/cm^2/s in the same energy range.
  Preliminary result shows that the time-averaged spectrum from T0+0 to T0+2 sec is well fitted by a single power-law with a photon index of 1.3 =B1 0.2 (chi^2 / d.o.f. =3D 22/20).

  report:
  We performed the Swift/BAT, and Suzaku/WAM joint fit spectral analysis of GRB 070714B (Swift-BAT trigger #284856; Racusin, et al., GCN Circ. 6620). The time interval of the spectral data for each instrument is chosen from T0(WAM) to T0(WAM)+2 sec where T0(WAM) is the trigger time of WAM at 04:59:29.247 UTC. The energy ranges which we used in the joint spectral analysis are 14-150 keV and 100-2000 keV for Swift/BAT and Suzaku/WAM respectively. The spectral data of two instruments are fit with the spectral model multiplied by the constant factor to take into account the systematic uncertainties in the response matrices of each instrument.
  The spectrum is well fit with a power-law with exponential cutoff model (dN/dE ~ E^{alpha} * exp(-(2+alpha)*E/Epeak)). The constant factors of each instrument agree within 10%. No systematic residual from the best fit model is seen in the spectral data of each instrument. The best fit spectral parameters are: alpha = -0.86 +- 0.10 and Epeak = 1120 (-380/+780) keV (chi2/dof = 64/69). The energy fluence in the 15-2000 keV band calculated by a power-law with exponential cutoff model for this two-second interval is 3.7 (-0.6/+1.3) x 10^-6 erg/cm2 (assuming the constant factor of the BAT is fixed to 1).

  On the night of 2007 July 18 (UT) we observed the field of GRB 070714B with the 10m Keck I Telescope (+LRIS) for 780 seconds in R and 920 seconds in g', starting at 14:30 UT. We detect a single, very faint source consistent with the position reported by Melandri et al. (GCN 6621) and inside the refined (GCN 6627) and improved [1] XRT error circles, in both filters. The location of this source is:

  RA = 03:51:22.23
  Dec = +28:17:50.8

  The object has an approximate magnitude of R~25.5, calibrating relative to the USNO-B2.0 star at (03:51:21.5973, +28:18:55.810). It does not appear visibly extended in our imaging. This rules out the presence of a bright host galaxy and, comparing to the magnitude reported by Levan et al. (GCN 6630) suggests a rapid late-time afterglow decay rate of the afterglow.

  Gemini Nod & Shuffle spectroscopy on the host of GRB 070714B shows a single emission line at 7165 A. A photometric redshift based on Gemini grizJHK observations with GMOS and NIRI strongly implies that this is the 3727 A [O II] line. This places the host at a redshift of z=.92
  The Swift BAT discovery data show the burst to have had a short, hard main component of three seconds duration followed by a soft, longer duration tail (Sakamoto et al. GCN 6623). The main component also shows a small spectral lag (Norris et al. GCN 6631). Both of these observations are consistent with GRB 070714B being a short GRB. This then would be the highest spectroscopically confirmed redshift of a short burst.
  The observed fluence of 7.2 x 10^-7 erg/cm^2 (Barbier et al. GCN 6638) at a redshift of z=.92 corresponds to an isotropic energy release of Eiso = 1.6 x 10^51 erg.

  Graham: GRB 070714B - Discovery of the Highest Spectroscopically Confirmed Short Burst Redshift
  Abstract: Gemini Nod & Shuffle spectroscopy on the host of the short GRB 070714B shows a single emission line at 7167 angstroms which, based on a grizJHK photometric redshift, we conclude is the 3727 angstrom [O II] line. This places the host at a redshift of z=.923 exceeding the previous record for the highest spectroscopically confirmed short burst redshift of z=.546 held by GRB 051221. This dramatically moves back the time at which we know short bursts were being formed, and suggests that the present evidence for an old progenitor population may be observationally biased.

  Graham: GRB 070714B - Discovery of the Highest Spectroscopically Confirmed Short Burst Redshift
  Abstract: We detect the afterglow and host galaxy of GRB 070714B. Our observations of the afterglow show an initial plateau in the lightcurve for approximately the first 5 to 25 minutes, then steepening to a powerlaw decay with index alpha = 0.86 +/- 0.10 for the period between 1 to 24 hours post burst. This is consistent with the X-ray light-curve which also shows an initial plateau followed by similar subsequent decay. Such an initial plateau, commonly observed with both long and short GRBs, is suggestive of ongoing central engine activity. We also detect a host galaxy at the location of the optical transient. Our Gemini Nod & Shuffle spectroscopic observations of the host show a single emission line at 7167 angstroms which, based on a grizJHK photometric redshift, we conclude is the 3727 angstrom [O II] line. This places the host at a redshift of z=0.923 which, along with the subsequent probable spectroscopic redshift determination on GRB 070429B of z=0.904 by another group, significantly exceeds the previous highest spectroscopically confirmed short burst redshift of z=0.546 held by GRB 051221. This dramatically moves back the time at which we know short bursts were being formed, and suggests that the present evidence for an old progenitor population may be observationally biased.

  He Gao et al.: Searching for magnetar powered merger-novae from short GRBs
  The merger of a double neutron star (NS-NS) binary may result in a rapidly rotating massive NS with an extremely strong magnetic field (i.e., a millisecond magnetar). In this case, the magnetic spin-down of the NS remnant provides an additional source of sustained energy injection, which would continuously power the merger ejecta. The thermal emission from the merger ejecta would give rise to a bright optical "magnetar-powered merger-nova". In this work, we carry out a complete search for magnetar-powered merger-nova from \emph{Swift} short gamma-ray burst (SGRB) sample. We focus on short GRBs with extended emission or internal plateau, which may signify the presence of magnetars as the central engine. We eventually find three candidates of "magnetar-powered merger-nova" from the late observations of GRB 050724, GRB 070714B and GRB 061006. With standard parameter values, the magentar remnant scenario could well interpret the multi-band data of all three bursts, including the extended emission and their late chromatic features in the optical and X-ray data. The peak luminosities of these merger-novae reach several times $10^{42}~{\rm erg~s^{-1}}$, more than one order of magnitude brighter than traditional "kilo-novae" with peak luminosity of $\sim 10^{41}~{\rm erg~s^{-1}}$. Intense, multi-color late time observations of short GRBs are encouraged to identify more merger-novae in the future.
