[vsnet-alert 1490] Bright outburst of CR Boo

Bright outburst of CR Boo

   Gary Poyner reports the helium cataclysmic variable CR Boo is undergoing
a bright outburst.

   The last begenning of bright outburst (presumable superoutburst) occurred
on Jan. 8 (cf. vsnet-alert 1418).  The interval of 43 d seems to support
the suggested supercycle of 40-45d (cf. vsnet-alert 1404; Kato et al. in
preparation).  Time-resolved photometry is urged.
