(meteorobs) More Xi Bootids 02-04/05-00

     Although the wind chill was rather low,I still enjoyed a very busy, sometimes
exciting 3.25 hrs of teff last night (Sat morning).  I again had the pleasure of a -3
meteor, though this one was very brief and up somewhat behind me.
   All in all I saw 43 meteors, not bad at all for a Febuary night, though many were very
dim (see magnitude distribution).  The final period saw 19 meteors!
   Most pleasing of all was the sharp radiant I plotted at 14hrs 09 min + 14 for the Xi Bootids.  This is a little below and to the right of the radiant posted at NJAA.  It matches my plotted radiant from the previous night very nicely.  Two other meteors fell with 4 degrees of the center of this radiant.  All had acceptable speed, none were brighter than +3.
   I feel I have eliminated observer bias as much as possible, as I did not know exactly where the radiant was when I went out this morning.  This will be more of a problem tonight,
as, after two nights of plotting, I pretty much know where the (my plotted) radiant is now.
