+ fits the IMO working list radiant position better than
  the more recent video radiant (160 +27) as presented in
  Robert Lunsford's Meteor Activity Outlook 
* there is some chance of this one being a COM
enumerations starts in the 25/12/2008 session
all coordinates in mm from the lower left corner of the map
subjective velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast

Comments:
Not as windy as last time, instead freezing cold. Ursids are
gone and rates are not as high as one could have hoped. We'll
see whether there'll be another clear night this year.

Please note: d = degrees, all times in UT
