AMS Meteor Activity Outlook by Robert Lunsford
* average radiant height (est.)
~ estimated with r=3.0, deltalm=0.0 and est. radiant height
+ How am I supposed to distinguish between these two?
  NTA radiate north of the ecliptic, STA south of the ecliptic
  so I tried to determine wheather the suggested radiant of a meteor 
  is rather north or south of 52d/+19d.

all coordinates in mm from the lower left corner of the map
velocity scale:
1 - very slow; 2 - slow; 3 - medium; 4 - fast; 5 - very fast

Comments:
An already chilling October night, yet a good opportunity to
go and see what the Taurids are about. I found shower associtation
particularily difficult, but do hope I got nothing fatally wrong.
Nicest activity was surprisingly the two latter Sporadics that 
were bright and trainy.
