Hi Juergen, all,

> Are these problems seem to be a cause of the MPC February hacking!?

They are.

If you look at the list of comets on the new MPC site,

http://www.minorplanetcenter.org/iau/Ephemerides/Comets/Soft02Cmt.txt

you'll see that 103P (and other comets updated since mid-February)
are listed. Look at the list on the old site,

http://www.cfa.harvard.edu/iau/Ephemerides/Comets/Soft02Cmt.txt

and those comets aren't there, or have old data.

If you're running with an older version of Guide, it's attempting
to load the 'cfa.harvard.edu' version. Guide has no way of knowing
that that version dates back to February, and doesn't notice that
103P hasn't been updated.

Run with the current version, get current comets from MPC, and
you'll see 103P.

Comets are a confounded nuisance in Guide, mostly because we're
trying to merge the MPC's list of "currently observable comets" with
historical data, and trying to handle the strange changes in
designations that can occur in that process. Weird things can happen,
with comets being mysteriously "doubled" (one with an old name, the
other with the new name) or missing. Ideally, we'd be able to get a
single list of all comets, in much the way that MPCORB provides a
single list of all known asteroids. But that doesn't exist quite yet.
