(meteorobs) Dust Trail of Eta Aquariids in 2013

[Chris Steyaert]

   Hi All,


For sure there was good 'radio' activity around 6h UT this morning 
for European observers.
See www.rmob.org/livedata/main.php  Observers Haik, Hvezdarna Vsetin, Gansel.

But it is too soon now to say if there was some sort of an outburst, 
or if it was just the rise to the normal maximum. We'll know when 
more observations come in, and we have a view on the complete activity.

And the -1197 trail is for the Americas.


         Thanks,

         Chris
