Hi Bernd,

   It just occurred to me that there's another way to get Guide to
recognize Machholz (1994r).  That would be to download the file

http://www.projectpluto.com/machholz.txt

   Then run Guide and click on Extras... Add MPC Comets/Asteroids,
and click on the line at the bottom.  This will bring up a file-selector
dialog;  select 'machholz.txt'.

   'Machholz.txt' contains the same elements Guide already uses,
except that I've added in some probably not-very-accurate magnitude
data.  Guide will use these new elements instead of the old ones, 
and 1994r will start to behave "normally".
