>For the first time in six months a note from the Carribean. But when you
>are at the perfect location to observe the possible activity of the
>2-rev trail at 7h53 UT (Nov 17) and the 4-rev at 7h51 UT (Nov 18), I
>ain't gonna miss it!
>I've tried to start this year's Leonid observations at the 16th. But
>this night was clouded. Of course, it did start to get clear at dawn.
>That's Murphy for you.
>Last night I had more succes. At the beginning of the night it looked
>very promissing, but later that night some clouds drifted in.
>Observations were three times interupted by clouds and even rain, of
>course also from 7h40 untill 7h53 UT. That's Murphy again, to have rain
>at the predicted time of possible maximum activity of the 2-rev trail at
>7h53 UT.
>I started my observations at 6h00 UT. The moon wasn't that much of a
>nuisance, because I looked in the northwestern direction. The limiting
>magnitude hovered all night around 6.0. The clouds were a nuisance, as
>you can see at the tabulated values of F.
>In the beginning the Leonid activity was very low, and it remained low
>for over an hour. Then I had to interupt my observations for the first
>time because of rain. After I resumed my observations at 7h25 UT, the
>activity of the Leonids had increased considerably. As the predicted
>time of possible maximum activity of the 2-rev trail was approaching, I
>was hoping the activity would steeply increase to a minor storm level.
>This didn't happen. After 8h00 UT the activity stayed high, but slowly I
>grew tired. I had the impression the activity dropped again after 8h45
>UT. I am not sure, because I started falling asleep. That's why I omited
>the unreliable observations which I made after 8h45 UT in this report.
>Noteworthy was the lack of real bright Leonids. Not one of the Leonids I
>observed could even reach the brightness of Jupiter. The two Taurids
>were beautiful, as always. They were majestically soaring through the
>sky with a bright head and a faint tail.
>Now I will start the preparations for another observation run. Coming
>night I hope to see some activity of the 4-rev trail. I keep my fingers
>crossed.
