Results of the IMO Video Meteor Network - March 2007
====================================================
After a much too warm winter, which was not favourable to most observers due
to clouds, an unusually sunny begin of spring followed at many sites.
Especially in the middle of March virtually every observer enjoyed clear
skies such that we obtained in five consecutive nights over a hundred
observing hours. In the other nights it was often clear, too, such that in the
end we made it to up to about 1500 hours of effective observing time (the data
of Sraka are still missing). So it's the first March with over thousand hours -
a result that we barely missed in February. After checking all data, less than
one hour was missing in the end.
With 2.1, the average number of meteors per hour remained slightly under the
long-term average for March. Still, those 3000 meteors increased the video
meteor database for this month once more by about 50%.
Highlight of March was a bright fireball that occured in the early evening
of March 15 and was recorded by a number of fireball cameras (e.g. by Mark
Vornhusen). Our new Italian observer Biondani Roberto was lucky, too.
He recorded this bolide only because his Mintron camera was accidentally
switched on an hour early. According to his sum image, the fireball was
visible for about 4.5 seconds and should have been at least of magnitude -10.
It showed a number of flares and clear fragmentation towards the end.
