With our program of Swift monitoring of the Galactic Bulge region
(Atel #4109), we detect renewed activity of the X-ray binary XTE
J1739-285. Using the pipeline of Phil Evans (Evans et al. 2007, A&A,
469, 379), we find that the source count rate is about 34 counts/sec
in data taken on 4 September from 5:33 to 12:02 UT, with 372 seconds
of exposure time on source. We note that the source is heavily piled
up, since the data were taken in photon counting mode as part of an
imaging survey and hence the count rate should be taken with caution.
We note that the previous outburst's Swift observations showed count
rates about half as large, so we may be witnessing a brighter outburst
than the previous one. Further observations are needed, not only at
other wavelengths, but also at high energies.
