The transient Be X‐ray pulsar GRO J1750‐27 was originally detected in 1995 by CGRO/BATSE during a giant outburst. After a long period of quiescence the source was detected in another outburst early 2008. Following this outburst with hard X‐ray data from INTEGRAL and Swift, the orbital parameters have been confirmed and improved and a clear spin‐up measured.For the first time the broad‐band spectrum and pulse profile have been obtained, making it possible to estimate the source distance and the magnetic field strength. We discuss the evolution of the spectrum and pulse profiles over the outburst in 2008.
The Swift Burst Alert Telescope (BAT) triggered on GRB 080602 (trigger 312958) at 01:30:28 UT, (Beardmore et al., GCN Circ. 7781). This was a 2.048 s rate-trigger on a long burst which showed two well separated main peaks with a T90 = 74±7 s. Swift slewed immediately to this burst and XRT began follow-up observations at T + 118s, and UVOT at T + 124s. Our best position is the UVOT-enhanced XRT location RA(J2000) = 19.17574 deg (01h 16m 42.18s), Dec(J2000) = −9.23207 deg (−09d 13′ 55.4′′), with an error of 1.7 arcsec (90% confidence).
