>Hi all,
>
>Here another report from the Carribean. It ain't easy to observe one
>night, go to work the next day and going to observe the next night
>again. I planned to go to bed early, rise at 00h30 local time (04h30 UT)
>and to start observing from 01h30 local time. Alas, my body decided
>otherwise. I didn't hear the alarmclock and I woke with a start at 02h45
>local time. Swiftly I packed my gear in the car, looked at the sky for
>two minutes, saw no meteors and concluded the show hadn't started yet.
>The scene had completely changed when I arrived at the Wela hill. When I
>was installing my equipment, I saw already 6 Leonids. So I started
>observing at once. At 3h20 local time (7h20 UT) I started observing. And
>the activity was on the rise! But maximal activity was a bit early. From
>7h30 untill 7h35 I counted 15 Leonids. And the clouds were really
>bugging me at that time (see the F-value for that time). Was this the
>activity of the 4-rev. trail a bit earlier than expected, or was this
>another trail? Later the activity dropped, but there were still many
>Leonids to be seen. At first I saw mostly faint Leonids, later that
>night the average magnitude increased. At the end a lot of clouds moved
>in. I waited a while. Through small holes in the clouds I saw three
>other Leonids, but the clouds didn't disappear. Even worse, it started
>to rain. Then I quit, because it was only a quarter of an hour untill
>dawn at 6h local time (10h UT).
>I have another go tonight. If I'm succesfull, you will see the results
>tomorrow.
