Dear CBAers,

Australites, get thee to a telescope!  V803 Centauri finally jumped into
what appears to be a superoutburst - at a fairly convenient time of
year too.  We have a lot of coverage at normal outburst and practically
none at super.  No going to the movies tonight!  The putative superhump
period is just about 27 minutes, so the star is a real action adventure
movie all by itself.

I'm at the Rochester AAS meeting right now, and will take 6 days to
get to Bio2.  Communications will be a little stunted till I get
there.

Hi CBAers,

Just a quick note to let you know, in case you haven't seen them yet, that
we've updated our network pages to more accurately reflect our membership,
to include additional information about member stations, and to streamline
the display of information.  Comments and questions about the new network
pages are welcome.  Also, if you wish to add, change, or correct
information on the pages, please click on the link at the bottom of each
network page that leads to a station information form which you can fill
out and submit over the web.

Also, on this new station information form, we've included a few questions
that ask for information which we didn't ask for earlier -- primarily
about your non-astronomical interests.  These certainly aren't meant to be
intrusive, but to help present a network with more of a personal dimension
(one a bit more of individuals than of equipment), I encourage you to fill
out these additional fields.

Aloha,

Jonathan
CBA Hilo

Dear CBAers,

This report by Tonny seems awfully interesting.  With this sky position,
he has no chance of learning a usefully precise superhump period from
European observations alone.  Time for the Yanks and the Kiwis to jump
into the fray and measure those superhumps!  With that longitude spread
we'll certainly get Psh despite the very unfavorable time of year.

Re other objects, we have campaigns going on V1315 Aql and V603 Aql.
Both are in need of attention.  V603 is especially good for the smaller
scopes since it is plenty bright and has no hemispheric loyalties.

Please note there's an error in the coordinates I listed for this object. The coordinates I quote (14h32m25.88s, -00d33'00".9) are actually B1950, not J2000. The object is listed as Vir4 in the Downes, Webbink and Shara catalogue, at J2000 coordinates 14 35 00.14, -00 46 07.0.

Regards,
Tonny

Thanks John, for pointing this out !
