[vsnet-alert 4004] BY Cam activity

BY Cam activity

  As already pointed out by Gary Poyner, the polar BY Cam is very active.
The apparent short-term variation suggests the orbital variation may be
strongly enhanced.  Time-resolved observations (photometry, spectroscopy,
polarimetry, X-ray observations) may be useful.  BY Cam has an orbital period
of 0.13979 d.
