The Swift/BAT hard X-ray transient monitor reports increased activity in the
15-50 keV band for the transient pulsar and Be/X-ray binary V0332+53. Starting
on 2009-11-24 (MJD 55159), the source has increased rapidly in intensity from an
undetectable level (one-sigma upper limit of 0.002 cts/cm2/sec or 8 mcrab) up to
a current level of 0.012 ± 0.003 cts/cm2/sec (50 mcrab) on 2009-11-29. This is
the highest rate seen in the BAT monitor since its outburst in late October 2008
(Krimm et al, ATel #1792).
