Dust trails: not expected and not observed.

Introduction
The year 1999 is coming and also the parent-body of the Leonids (comet 55/P Tempel-Tuttle) is approaching the inner parts of our solar system. Because of that meteor observers are keen on tracking down a possible (minor) outburst of the Leonids as an omen for the greater things to come in 1998 and/or 1999. This year is the first chance to see a possible enhancement of the Leonids. The weather did not cooperate during the maximum night 16/17 november 1993, there was a lot of cirrus and only the first hour after the Leonid radiant rises above the horizon was "clear". However, the nights 17/18, 18/19 and 19/20 november were clear at my location. No enhancement was observed [1].

Observations

16/17-11-1993
My last observing night on our "old" location, the watertower near Harderwijk. I could observe only one hour around the time the radiant rises above the horizon. No Leonids seen. After one hour cirrusclouds moved in from the west.

17/18-11-1993
A hazy and cold night. I was able to collect four hours of data this night. Normal Leonid activity with rates up to 4 an hour. Best Leonid was a magnitude 0.

18/19-11-1993
Two hours of observing time: normal/low Leonid activity, 2 Leonids an hour.

19/20-11-1993
One hour, very clear sky. Only two Leonids seen in this period.

Also other meteor observers around the world didn't see anything unusual.
