Remarks:

Observing started at approx. 23 UT, but there were too many clouds at that time.
After the sky cleared, the air got quite moist.
The Taurid in the last period was (and is) one of the most beautifull meteors
I ever saw. It was orange/red and visible for at least 2 seconds and flared
several times.

Remarks:

The air was quite moist all night and at least one small Lenticularis cloud
was present all the time. Still, untill 1 UT the conditions were reasonable
for official observing. After 1 UT some serious patches of cloud drifted in
causing very uneven conditions across the skies. I continued observing but
in a less strict way. A maximum of 11 meteors per minute was seen around 
4:15 UT. Only one real earthgazer was observed and only two real bright Leonids
( a -4 and a -7)
