[vsnet-alert 5949] V660 Her rebrightening!

V660 Her rebrightening!

   The SU UMa-type dwarf nova V660 Her, once faded from a short outburst,
has risen again!  The short outburst should have been a precursor to
superoutburst!  Time-resolved photometry during the present (likely)
main superoutburst is strongly encouraged.  The combined data with the Ouda
observation of the precursor would be valuable in studying the evolution
from a precursor to the genuine superoutburst.
