Description
Swift has been monitoring the accreting millisecond pulsar IGR J17498-2921 since the start of its outburst in 2011 August 12 (ATels #3551, #3555, #3556). We detected two X-ray bursts on Aug. 18 and 28. During the first ~12 days the average persistent XRT count rate remained approximately constant at 3-7 c/s. Around Aug. 24 the source count rate started to decrease slowly, down to ~1 c/s on Sep. 11.
