After my first attempt for the 1998 Leonids was washed out Sunday
night/Monday morning, I was able to go out again this morning, and with some
dodging of clouds, get some observing in. No meteor storm was here this
morning, but I was really impressed with the number of negative magnitude
meteors. I set up at my dark sky site in Awendaw under perfectly clear skies
with the Leonid radiant barely above the horizon. My early arrival was
rewarded with several "sky-crossers" and "horizon-huggers" that seemed to
travel for minutes. But clouds moved in shortly after my first hour, so a
roadtrip was ordered.

Off to Sullivan's Island in hopes of a sea breeze pushing clouds away. On
the drive there I could see bright meteors "dropping" from the sky...even
seeing one very bright one in the rear view mirrors. I pushed on the gas
pedal a little harder.

My relocation worked as I arrived on the island under clear skies. Quickly
setting up, the breeze not only helped with cloud cover, but also
mosquitoes, as the 60+ degree (F) temps were bringing them out.
Unfortunately, once again about an hour later, clouds moved in ending my
session for the night.

Of the 85 Leonids I saw, 12 were bright enough to be classified as a
fireball. The brightest was a -7.0 magnitude. I was also impressed with the
train production of the Leonids, with trains visible for dozens of seconds
frequently seen. As I write this we have perfectly clear skies...the low has
moved off the coast, and we should have good skies for my session tonight.
Below is my summary:
