Here are my three day observations centered aroung the Lyrid Peak.
The highlight was a mag-7 fireball that ended in a terminal burst

Meteor 30 was a fireball. It may have been a bolide, given its
characteristics.
-Appeared at 09:25 UT, halfway between Vega and Beta Scorpio
-at least a Mag 7 terminal burst
-8-10 second train
-at *LEAST* 45-50 degree path
-duration app 2.5 sec.
-moved down towards horizon (away from Vega)
-began a quick steady rise in magnitude after initial appearance, was
already a
fireball by the time of the the terminal burst. “Explosion” at
termination
caused an easily visible glow against the top of an oak tree that was
“under” the burst.
-did not notice any sound, but was not being particularly attentive
for them
(inexperience!)
Best description--looked like a patriot missile that found its
prey...only much
faster. Unlike anything I’ve seen.
