Galloway et al. (2007; ATEL #1086) reported that the X-ray luminosity of the accreting millisecond pulsar HETE J1900.1-2455 exhibited a steady decay between 14 and 27 May, and suggested that the source may be finally returning to quiescence after an outburst of ~2 years. A similar declined was seen in the optical flux of the source (ATEL #1090). To follow the X-ray luminosity and spectral behavior of the source, we observed it with Swift/XRT during a ~1 ksec exposure performed on May 31, 2007 (00:02-00:18 UT).
