Romano (INAF-OAB), T. Sakamoto (NASA/ORAU), M. Stamatikos (NASA/ORAU) and L. Vetere (ASDC) report on behalf of the Swift Team: At 15:12:00 UT, the Swift Burst Alert Telescope (BAT) triggered and located GRB 060714 (trigger=219101). Swift slewed immediately to the burst. The BAT on-board calculated location is 227.872, -6.546 (15h 11m 29s, -06d 32' 45") (J2000) with an uncertainty of 3 arcmin (radius, 90% containment, including systematic uncertainty). The BAT light curve shows a single peak with a duration ~20 seconds. The peak count rate was ~500 counts/sec (15-350 keV). The XRT began observing the field at 15:13:39 UT, 99 seconds after the BAT trigger. XRT found a bright, fading, uncatalogued X-ray source located at RA(J2000) = 15h 11m 26.5s, Dec(J2000) = -06d 33' 57.5", with an estimated uncertainty of 4.7 arcseconds (90% confidence radius). This location is 83 arcseconds from the BAT on-board position, within the BAT error circle. The initial flux in the 2.5s image was 1.0e-08 erg/cm2/s (0.2-10 keV). UVOT took a finding chart exposure of 100 seconds with the White (160-650 nm) filter starting 109 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 (227.8602,-6.5662) or (15h11m26.45s,-06o33'58.3") with a 1-sigma error radius of about 0.5 arc sec. This position is 2.0 arc sec. from the center of the XRT error circle. The estimated magnitude is 19.2 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 0.08. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5312 SUBJECT: GRB 060714, optical observation DATE: 06/07/14 17:11:15 GMT FROM: Shouta Maeno at U.of Miyazaki E.Sonoda, S.Maeno, M.Yamauchi (University of Miyazaki) "We have observed the field covering the error circle of GRB060714 (GCN 5311) with the unfiltered CCD camera on the 30-cm telescope at University of Miyazaki.

Hertfordshire), Paul Vreeswijk (ESO), Johan P.U. Fynbo, Jens Hjorth (DARK, NBI), Rhaana Starling (U. Amsterdam), D. Alexander Kann (TLS Tautenburg) and Dieter Hartmann (Clemson University) report on behalf of a larger collaboration: Using FORS1 on the Very Large Telescope, we have obtained 3*30 min spectra (300V) of GRB 060714 (Krimm et al., GCN 5311). The acquisition image shows the UVOT optical afterglow candidate to have R ~ 20.4 on July 14.990 (8.54 hours post-burst).

Perri, M.L. Conciatore, L. Vetere, M. Capalbi (ASDC), D.N. Burrows (PSU) report on behalf of the Swift/XRT team: We have analyzed the first 9 orbits of XRT data from GRB 060714 (Krimm et al., GCN 5311). A 4.2 ks Photon Counting mode image provides a refined XRT position: RA(J2000) = 15h 11m 26.5s, Dec(J2000) = -06d 33m 59.3s with an uncertainty of 3.8 arcsec (90% containment). This position is 1.2 arcsec away from the on-board UVOT position of the optical afterglow reported in GCN 5311. The X-ray light curve displays two flares during the first orbit at about 140 and 180 seconds after the BAT trigger. The afterglow decay from T+300s to T+40ks can be fit with a broken power-law with an initial decay slope of -0.4+/-0.2, a break at 3.7 (+1.7)(- 1.0) ks, and a post-break slope of -1.29+/-0.15. A power-law fit to the 0.3-10 keV spectrum from T+107s to T+248s gives a photon index of 1.97+/-0.05 and a column density of (1.89+/-0.15)e21 cm**-2. We note the Galactic hydrogen column density in the direction of the burst is 6.7e20cm**-2. If the burst continues decaying at the current rate we estimate a 0.3-10 keV unabsorbed flux of ~6e-13 ergs cm**-2 s**-1 at T+24hr. This circular is an official product of the Swift XRT Team. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5322 SUBJECT: GRB 060714 : Liverpool Telescope Observations DATE: 06/07/15 14:28:01 GMT FROM: Andrea Melandri at Liverpool John Moores U A.

E. Cobb (Yale), part of the larger SMARTS consortium, reports: Using the ANDICAM instrument on the 1.3m telescope at CTIO, we obtained optical/IR imaging of the error region of GRB 060714 (GCN 5311, Krimm et al.) with a mid-exposure time of 2006-07-15 01:18 UT (~10.1 hours post-burst). Total summed exposure times amounted to 36 minutes in I and 30 minutes in J. The afterglow of GRB 060714 (GCN 5311, Krimm et al.) is well-detected in the I-band, but only marginally detected in J. The following preliminary photometry was calibrated using several USNO-B1.0 stars in the I-band and several 2MASS standards in J. The I-band error is dominated by the error in the photometric calibration, while the error in the J-band in dominated by the error in the afterglow measurement. time post-burst I magnitude J magnitude ------------------------------------------------------ 10.1 hrs 20.72 +/- 0.17 19.74 +/- 0.18 //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5324 SUBJECT: GRB060714: optical observations DATE: 06/07/16 17:37:27 GMT FROM: Alexei Pozanenko at IKI, Moscow E.

The BAT ground-calculated position is RA,Dec = 227.854, -6.545 deg {15h 11m 24.9s, -6d 32' 42.3"} (J2000) +- 1.5 arcmin, (radius, sys+stat, 90% containment). The partial coding was 27%. The mask-weighted lightcurves show an initial triangular-shapped peak starting at T-15 sec, peaking at T_zero, and ending at T+55. Then come two peaks, each about 20 sec FWHM, peaking at T+76 and T+90 sec; the last peak ending at T+120 sec. We note that the XRT follow-up observation does not start until the trailing edge of the second peak. T90 (15-350 keV) is 115 +- 5 sec (estimated error including systematics). The time-averaged spectrum from T-13.3 to T+120.6 is best fit by a simple power-law model. The power law index of the time-averaged spectrum is 1.99 +- 0.10. The fluence in the 15-150 keV band is 3.0 +- 0.2 x 10^-6 erg/cm2. The 1-sec peak photon flux measured from T+75.42 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. We apologize for the long delay in issuing this standard BAT Second Circular. //////////////////////////////////////////////////////////////////////// TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5336 SUBJECT: GRB060714: optical observations DATE: 06/07/18 13:51:44 GMT FROM: Alexei Pozanenko at IKI, Moscow V.
