This year's Leonids were marked from excellent lunar conditions. The weather

was also very friendly to most of the observers around the world.

 

The strongest peak observed is around 18h20min UT which was suitably

situated for the observers in East Asia and Australia. The rates during this

peak reached more then 2800 meteors per hour. This is well below the

theoretically predicted peak levels which were around 5000 according to

Lyytinen/Nissinen/van Flaudern or 8000 in Asher/McNaught's model.

 

As far as the first peak, observed from America, is concerned rates were

between 1000 and 1500 meteors per hour. However there is still not enough

data reported from it especially about the time after 11 UT.

 

The first activity profile is derived from the observations of 38 observers.

It is aimed to give a general view of the observed shower and no conclusions

can be made on this stage. The following detail analysis will tell us more

about the shower and the dust trail models.

 

Data of the following observers is included in the preliminary profile. The

countries in brackets show the place where observations were carried out,

not necessarily his home land :

Albert Kong (USA), Andreas Buchman (Germany), Andrzej Skoczewski (Poland),

Antonio Martinez (Venezuela), Brian Shulist (Canada), Camila Bacher (USA),

Many thanks to all the observers that have contributed their data. Also to

the favorable weather conditions whish are not so typical for this part of

the year.
