[vsnet 669] WX CRA intercomparison / update

[Berto Monard <LagMonar@csir.co.za>]

Hi,

I received some interesting and encouraging responses so far on
this initiative. And indeed Northern observers are interested too
but they can't see so deep down under. 
I could suggest they organise their own intercomparison, if they 
have a need at all to determine non-existing sequences or rectify
discordant ones. We could organise something together?
As far the Southern sky is concerned, a lot is to be done and it
would be nice if we could sort something out. WX CRA is only a
beginning. Hopefully we will carry on.. and suggestions are
hereby welcomed.
I can think (off hand) on one discordant sequence on the V1830
SGR chart from the RASNZ. I discussed it allready with B Sumner.
It concerns a close by reference star just North of V1830.  It's
given a magnitude of 12.0V. I have never seen it, even under
optimal conditions, and consider it to be well <12.5. VSNET (T.
Kato) gives a value of 12.55V for it which looks more likely to me.
What do you get?

As things progress I will keep you informed!

Best regards,

Berto
