Dear CBAers,

I've just finished my first pass through the received data on this newly
discovered dwarf nova.  It has very, very powerful superhumps, well
attested by the data from Berto, Chris Middleton, Grant Christie, and
Peter Nelson.  And the early coverage shows the growth of the superhump, a
phase we seldom see at all.  So we're poised for a very good campaign.

In particular, it seems likely that with long time series from several
sites around the world, we can detect the "orbital sidebands" in the
superhump that cough up the coveted value of Porb.  About half the time,
the superhumps do that - but they *never* do it when the observational
coverage is spotty.

The V803 Cen campaign is near an end now - so I figured it's a good time
to end the campaign and concentrate all that southern energy on our newly
discovered friend.  Long runs, fire away, and may a thousand stars
decorate those long nights of yours.
