TITLE: GCN CIRCULAR NUMBER: 7750 SUBJECT: GRB 080514B: second epoch Swift XRT data confirms the X-ray afterglow DATE: 08/05/19 10:23:12 GMT FROM: Paolo Esposito at INAF-IASF,Milano P. Esposito, A. De Luca, A. Tiengo, G. Vianello (INAF-IASF MI), K.L. Page (U. Leicester) report: GRB 080514B was discovered by the SuperAGILE detector on May 14th, at 09:55:56 UT (Rapisarda et al., GCN Circ. 7715) and possibly detected at energies E>50 MeV in AGILE GRID data (Giuliani et al., GCN Circ. 7716). The first Swift/XRT observation was performed on May 14th at 20:12, starting about 37 ks after the GRB trigger (Page et al., GCN Circ. 7723). A likely afterglow candidate was found, with a flux decay described by a power-law (slope: 1.5+/-1.0; GCN Circ. 7723). The spectrum was modelled with an absorbed ( 1.2x10^21 cm^-2) power-law, with photon index = 2.06 (GCN Circ. 7723). Swift/XRT observed again the field of GRB 080514B on May 16th at 20:13, about 58 hours after the trigger. 6 ks of data in Photon Counting mode were collected in three consecutive orbits, spanning 5 hours. The candidate X-ray afterglow (GCN Circ. 7723) is significantly detected with a 0.3-10 keV observed flux of (1.9+/-0.8)x10^-13 erg cm^-2 s^-1 (assuming the spectrum of Circ. 7723). The new XRT data confirm the fading trend reported in (GCN Circ. 7723) and better constrain the decay slope at 1.6 +0.3/-0.2. We thank the Swift PI, N. Gehrels, for approval of this TOO, and the the Swift team (in particular the duty scientists and science planners) for performing it.
