The event was localized by SuperAGILE at approximately 38 degrees off axis, in the one-dimensional portion of its field of view, thus providing a narrow and long error box. The narrow side is 6 arcmin wide, while the long side is approximately 40 degrees wide. In the 20-60 keV energy range the event had a 10s duration, with a multi-peaked structure. The same event was also detected by Mars Odyssey. The IPN was thus able to reduce the SuperAGILE error box to the 100 sq arcmin error box whose corners are given by the following coordinates (RA, Dec): 322.962 (21h 31m 50.81s) 0.733 (0d 43m 59.69s) 322.774 (21h 31m 5.74s) 0.667 (0d 40m 2.78s) 322.867 (21h 31m 27.99s) 0.806 (0d 48m 21.16s) 322.678 (21h 30m 42.80s) 0.740 (0d 44m 23.63s) The centroid of the error box is at (RA, Dec)= (322.820, 0.737) and the maximal distance between the box corners is 0.283 deg, that is 16.9 arcmin.

Page, A.P. Beardmore (U. Leicester), S. Mereghetti (INAF - IASF Milano), M. Feroci and M. Tavani (INAF/IASF Roma) report on behalf of the Swift-XRT and AGILE teams: Following a ToO request, Swift-XRT started observing the field of GRB 080514B at 20:12 on 14th May, about 37 ks after the trigger. Within the SuperAGILE/IPN error box, there are two sources detected, one of which is much brighter and appears to be fading. We therefore believe this to be the X-ray afterglow of the GRB. Using 925 s of overlapping XRT Photon Counting mode and UVOT 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 = 322.84426, 0.70843 which is equivalent to: RA (J2000): 21 31 22.62 Dec (J2000): +00 42 30.3 with an uncertainty of 1.6 arcsec (radius, 90% confidence). This position is 1.7 arcsec from the i-filter object mentioned by de Ugarte Postigo et al., in GCN Circ. 7719. A spectrum of the three orbits of Photon Counting (PC) mode data (6 ks of data, spanning 37-49 ks after the trigger) can be modelled with an absorbed power-law of Gamma = 2.06 +0.35/-0.31 and NH = (1.2 +0.8/-0.6)x10^21 cm^-2, which is slightly in excess of the Galactic value of 3.75x10^20 cm^-2. The observed (unabsorbed) 0.3-10 keV flux is 2.34x10^-12 (3.14x10^-12) erg cm^-2 s^-1. This corresponds to an observed counts to flux conversion of 1 count = 3.96x10^-11 erg cm^-2. The light-curve can be fitted with a single power-law, with a slope of alpha = 1.5 +/- 1.0. If the light-curve continues to follow this decay, the count rate at 48 hours is predicted to be 6.6x10^-3 count s^-1 (an observed flux of 2.6x10^-13 erg cm^-2 s^-1). This circular is an official product of the Swift-XRT team. //////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 7724 SUBJECT: GRB 080514B: slow fading behaviour ?

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 burst light curve shows a multipeaked structure with a duration of ~7 s. As observed by Konus-Wind the burst had a fluence of 3.23(-0.26, +0.27)x10^-5 erg/cm2, and a 16-ms peak flux measured from T0+3.328 s of (2.07 +/- 0.43)x10^-5 erg/cm2/s (both in the 20 keV - 5 MeV energy range). The time-integrated spectrum of the burst (from T0 to T0+12.032 s) is well fitted (in the 20 keV-5 MeV range) by GRBM (Band) model for which: the low-energy photon index is alpha = -0.599(-0.134, +0.161), the high energy photon index beta = -2.48(-0.25, +0.18), the peak energy Ep = 224 (-22, +23) keV (chi2 = 72.3/76 dof).

Berkeley D. A. Perley, J. S. Bloom (UC Berkeley), H.-W. Chen (U Chicago), R. J. Foley, A. A. Miller, J. Shiode, J. Brewer, D. Starr, and R. Kennedy (UCB) report: On the night of 2008-06-07 (UT) we observed the location of the Super-AGILE burst GRB 080514B (GCN 7715, Rapisarda et al.) with Keck I / LRIS in g and R filters for 1080s and 960s respectively, starting at 12:53 UT. We detect a source consistent with the afterglow position (de Ugarte Postigo et al., GCN 7719) in both filters. Photometry within a 1.1" radius aperture gives an magnitude (calibrated to three nearby USNO B1.0 stars) of: R = 23.9 +/- 0.2 (t = 24.1 days) Compared to the measurement of Malesani et al. (R = 22.52 at 1.77 days, GCN 7734), this would suggest a decay index of only about alpha = 0.5 were this the GRB afterglow, which is unlikely at such late times. More likely, the source represents a relatively bright host galaxy of this burst. However, analysis of a 2x1200s Gemini-North spectrum using GMOS taken at the afterglow location (offset <0.5" from the host from a comparison from the Gemini i-band acquisition image) 1.9 days after the GRB shows no significant emission or absorption features over the usable spectral range from 4000-6720 Angstroms. The continuum flux extends all the way to 4000 Angstroms without evidence of Lyman-alpha forest absorption, which imposes a redshift constraint of z < 2.3. Further follow-up is encouraged.
