Circular_text	TITLE: GCN CIRCULAR NUMBER: 14638 SUBJECT: GRB 130514B: a long GRB detected by INTEGRAL DATE: 13/05/14 14:56:00 GMT FROM: Sandro Mereghetti at IASF/CNR S.Mereghetti (IASF-Milano), D.Gotz (CEA, Saclay), C.Ferrigno, E.Bozzo, E.Filippova (ISDC, Versoix), and J.Borkowski (CAMK, Torun) on behalf of the IBAS Localization Team report: a gamma ray burst lasting about 10 s has been detected by IBAS in the IBIS/ISGRI data at 13:26:32 UT of May 14. A preliminary analysis gives the coordinates (J2000) R.A.= 147.604 deg DEC.= -18.969 deg with an uncertainty of 3 arcmin (90% c.l.). The burst had a peak flux of about 1 counts/cm2/s (20-200 keV, 1-s integration time). Due to telemetry saturation we can only set a lower limit of 6x10^-7 erg/cmq on the fluence in the same energy range. A plot of the light curve has been posted at http://ibas.iasf-milano.inaf.it/IBAS_Results.html

The first good image made 3812 sec after GRB time at 2013-05-14 14:30:06.562 UT. On our first (180s exposure) good set we haven't found optical transient within INTEGRAL error-box (S.Mereghetti et. al GCN 14638). The 5-sigma upper limit has been about 16.5 mag The observations mae on large zenith distance z=83 deg. The message may be cited.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 14651 SUBJECT: GRB 130514B: Swift-XRT Observations DATE: 13/05/15 02:12:20 GMT FROM: Binbin Zhang at PSU B.-B. Zhang (PSU), Dirk Grupe (PSU) and D. Malesani (DARK/NBI) report on behalf of the Swift-XRT team: We have analyzed 2.0 ks of XRT data for the INTEGRAL-detected burst: GRB 130514B, from 5.0 ks to 10.8 ks after the INTEGRAL trigger. The data are entirely in Photon Counting (PC) mode. An X-ray source is detected within the INTEGRAL error circle. Using 1475 s of PC mode data and 2 UVOT images, we find an enhanced XRT position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 147.60859, -18.96517 which is equivalent to: RA (J2000): 09h 50m 26.06s Dec(J2000): -18d 57' 54.6" with an uncertainty of 1.8 arc sec (radius, 90% confidence). This position is 37 arcsec from the INTEGRAL position. The X-ray source was detect with a peak count rate of 0.31 count/s at ~ T0+5359s, where T0= 2013 May 14 at 13:26:29.510 UT, then faded to a count rate of 0.11 count/s at T0+11 ks. A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.17 (+0.31, -0.30). The best-fitting absorption column is 3.6 (+1.2, -1.1) x 10^21 cm^-2, in excess of the Galactic value of 3.6 x 10^20 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.9 x 10^-11 (7.2 x 10^-11) erg cm^-2 count^-1. A summary of the PC-mode spectrum is thus: Total column: 3.6 (+1.2, -1.1) x 10^21 cm^-2 Galactic foreground: 3.6 x 10^20 cm^-2 Excess significance: 5.0 sigma Photon index: 2.17 (+0.31, -0.30) The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00020275.

Detection_method	GROND
Circular_text	TITLE: GCN CIRCULAR NUMBER: 14657 SUBJECT: GRB 130514B: GROND observations DATE: 13/05/15 10:58:01 GMT FROM: Alexander Kann at TLS Tautenburg S. Schmidl, D. A. Kann (both TLS Tautenburg) and J. Greiner (MPE Garching) report on behalf of the GROND team: We observed the field GRB 130514B (INTEGRAL trigger 6843; Mereghetti et al., GCN 14638) simultaneously in g'r'i'z'JHKs with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG/ESO telescope at La Silla Observatory (Chile). Observations started in late twilight at 23:11:33.7 UT on May 14th, 9.75 hours after the IBAS trigger. They were performed at an average seeing of 1".6 and at an average airmass of 1.0. Inside the 1".8 refined XRT error circle (Zhang et al., GCN 14561), we do not detect any sources. Based on an observation with 1500 s integration time in g'r'i'z' and 1200 s integration time in JHK, centered at 0.42572 days after the trigger, we estimate preliminary 3-sigma upper limits (all in AB system) of g' > 24.7, r' > 24.4, J > 21.0, H > 20.7 and K > 20.0. Optically, this GRB is again very faint, similar to GRB 130513A (Schmidl et al., GCN 14639). Galactic extinction is negligible. The XRT spectrum shows strong absorption (Zhang et al., GCN 14561), and this is probably dark GRB. Given magnitudes are calibrated against GROND zero points (g'r'i'z') as well as 2MASS field stars (JHK) and are not corrected for the expected Galactic foreground extinction corresponding to a reddening of E_(B-V)=0.03 mag in the direction of the burst (Schlegel et al. 1998).

Circular_text	TITLE: GCN CIRCULAR NUMBER: 14659 SUBJECT: GRB 130514B Swift-BAT observations DATE: 13/05/15 12:25:14 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift J. R. Cummings (UMBC/CRESST/GSFC) and H. A. Krimm (USRA/CRESST/NASA) report on behalf of the Swift-BAT team: At the time of the INTEGRAL GRB 130514B (Mereghetti et al. GCN Circ# 14638), Swift was in a preplanned slew maneuver. BAT photon event data was collected during this slew. BAT saves such "slew survey" data when possible within telemetry constraints. The source was detected in a mosaic image. As seen in BAT, the burst was a single FRED peak about 7 +/- 1 seconds long. The source had about 10% mask coding in the BAT detector plane. The BAT spectrum is well-fit by a power-law function with a photon index of 1.72 +/- 0.21. The fluence from 15-150 keV in 8 seconds was (8.8 +/- 0.6) x 10^-7 ergs/cm^2/sec. Errors are 68% confidence.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 14665 SUBJECT: GRB 130514B: RATIR Optical and NIR Observations DATE: 13/05/15 19:03:13 GMT FROM: Alan M. Watson at Instituto de Astronomia UNAM Nat Butler (ASU), Alan M. Watson (UNAM), Alexander Kutyrev (GSFC), William H. Lee (UNAM), Michael G. Richer (UNAM), Chris Klein (UCB), Ori Fox (UCB) J. Xavier Prochaska (UCSC), Josh Bloom (UCB), Antonino Cucchiara (UCSC), Eleonora Troja (GSFC), Owen Littlejohns (ASU), Enrico Ramirez-Ruiz (UCSC), Jos A. de Diego (UNAM), Leonid Georgiev (UNAM), Jess Gonzlez (UNAM), Carlos Romn-Ziga (UNAM), Neil Gehrels (GSFC), and Harvey Moseley (GSFC) report: We observed the field of GRB 130514B (Mereghetti, et al., GCN 14638) with the Reionization and Transients Infrared Camera (RATIR; www.ratir.org) on the 1.5m Harold Johnson Telescope at the Observatorio Astronmico Nacional on Sierra San Pedro Mrtir from 2013/05 15.15 to 2013/05 15.16 UTC (14.12 to 14.55 hours after the BAT trigger), obtaining a total of 0.20 hours exposure in the r' and i' bands and 0.08 hours exposure in the Z, Y, J, and H bands. For a source within the Swift-XRT error circle (Zhang et al., GCN Circular 14651), in comparison with USNO-B1 and 2MASS, we obtain the following upper limits (3-sigma): r' > 22.49 i' > 21.95 Z > 20.53 Y > 20.54 J > 19.66 H > 19.72 These magnitudes are in the AB system and not corrected for Galactic extinction in the direction of the GRB. Our non-detection is consistent with the deeper upper limits of Schmidl et al. (GCN Circular, 14657) obtained a few hours earlier. We thank the staff of the Observatorio Astronmico Nacional in San Pedro Mrtir.

Circular_text	TITLE: GCN CIRCULAR NUMBER: 14695 SUBJECT: GRB 130514B: Further Swift-XRT Observations DATE: 13/05/22 20:39:24 GMT FROM: Binbin Zhang at PSU B.-B. Zhang (PSU), Dirk Grupe (PSU). D. Malesani (DARK/NBI) and J. Kennea (PSU) report on behalf of the Swift-XRT team: We have analyzed 6.8 ks of XRT data for the INTEGRAL-detected burst: GRB 130514B, from 314.3 ks to 321.1 ks after the INTERGRAL trigger. The data are entirely in Photon Counting (PC) mode. We confirm that the X-ray source reported in Zhang et al. GCN 14651 has been faded with current count rate of around 3e-3 count/s. The light curve can be modeled with a power-law decay with a decay index of alpha=0.98 (+0.27, -0.15). We therefore conclude that the X-ray source reported in Zhang et al. GCN 14651 is the X-ray afterglow of GRB 130514B.
