//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 16408 SUBJECT: GRB 140614C found in ground analysis of BAT data DATE: 14/06/15 14:51:46 GMT FROM: Jay R. Cummings at NASA/GSFC/Swift J. R. Cummings reports on behalf of the Swift-BAT team: The IPN reported a burst at 20:06:56. It occurred near the end of a Swift pointing on top of an approach to the SAA. No source was found onboard. In ground analysis a significant source was found at RA, Dec 147.423, 71.945, which is: RA (J2000) 09h 49m 41.5s Dec (J2000) 71d 56' 41" with an estimated 90% uncertainty radius of 3 arcmin. The burst was a single peak about 20 seconds long. The spectrum during the peak 10 seconds of the burst is best fit by a simple power law function with a photon index of 1.0 ± 0.3. The fluence from 15-150 keV in the 10 seconds was (1.6 ± 0.5) x 10^-7 ergs/cm^2. Errors quoted are 68% confidence. A Swift TOO has been requested. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 16410 SUBJECT: GRB 140614C: 1.23m CAHA (+EDIPO) observations DATE: 14/06/15 23:17:26 GMT FROM: Alberto Castro-Tirado at Inst.de Astro. de Andalucia A. J. Castro-Tirado (IAA-CSIC, ISA-UMA), J. Gorosabel (IAA-CSIC, UPV-EHU), S. Guziy (Univ. of Nikolaev), O. Rabaza (UGR), I. Syniavskyi, Y. Ivanov (Kiev Main Astronomical Observatory), R. Cunniffe, A. Gonzalez-Rodriguez, M. Jelinek, S. Jeong, O. Lara-Gil, S. R. Oates, R. Sanchez-Ramirez and J. C. Tello (IAA-CSIC) report: “Following the detection of GRB 140614C by Swift/BAT (Cummings et al. GCNC 16408) we obtained R-band images at the 1.23m telescope (+EDIPO) at Calar Alto Observatory in southern Spain, starting on June 15, 20:27 UT (i.e. 24.4 hr postburst). In the coadded image (6 x 300s), we see no credible optical candidate within the BAT error box when compared to the DSS-1 down to R = 20.5. Further observations are ongoing.”
