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 2008-10-17 (MJD 54756), 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 0.024 0.003 cts/cm2/sec (105 mcrab) on 2008-10-20. This is the highest rate seen in the BAT monitor since its outburst in late 2004 and early 2005 (Swank, Remillard and Smith, ATel #349).
