I'm at the annual meeting of the German meteor society -
http://meteoros.de/akm/seminar14/index.html - right now, and this morning
we learned about a new analysis of international video data that seems to
confirm with hard numbers that there is a significant deficit of radiants
in the southern sky: as you can see in S. Molau's summary slide
https://twitter.com/cosmos4u/status/447289852493434880/photo/1/large over
1/2 of all streams are located north of +30°N. Has this significant
hemispheric asymmetry also shown up in other data sets (e.g. radar) - and
if it's real: what could be the explanation?
