(meteorobs) Post-peak Lyrid Observations; East Georgia April 23, 2006

[Kim Youmans]

     Thunderstorms prevented me from observing the Lyrids Saturday morning,
but the skies cleared nicely last night and I was able to get in two hours 
under
exceptionally clear skies, LM +6.5.  The Milky Way was stunningly bright,
as was Juptier and a number of the meteors observed, in particular, a Lyrid 
fireball
that flared near its terminal point to around -5, and a -1 SPO that was 
silvery-blue.
The Lyrids put on a good display during the first hour, with 7 (and a 
potential eighth)
seen.  Their numbers dropped to just three during the second hour.
      During the first hour I was facing the Antihelion radiant during 
culmination and this
may have helped account for the high number of ANTs seen, four during that 
period,
though only one was seen during the second hour.  All told, an enjoyable 
night under
the stars given the number of bright meteors seen and the nice rates during
the first hour.
