(meteorobs) Leonids peak 1999 Obs [Central Texas, USA]




A hearty "Welcome to meteorobs" to Sue Worden, who recently got out to observe
during the peak night of the Leonids. Thanks for sharing your observing report
with us, Sue. Have you been recording meteors for long, and were you ever a
member of any of the meteor organizations, e.g., the American Meteor Society? I
noticed you estimated magnitudes for each meteor, as well as recording Limiting
Magnitude and exact break times, all of which are unusual for observers without
at least some experience or training in meteor observing!

Clear skies, and again welcome!
