[vsnet-outburst 9602] PU CMa superhumps update, precursor

PU CMa superhumps update, precursor

   Peter Nelson has reported another set of time-series photometry.
The data up to now have shown striking period evolution.
During the precursor stage, a longer superhump period of 0.0589(2) d
was observed, which switched to 0.05791(1) d.  The latter superhump
period is close to that (0.05799 d) observed in 2005.  The superhump
period is expected to increase at this stage.  Further continuous
time-resolved photometry is encouraged.
