Hi all,
These are my Lyrid observations from last week. I was able to enjoy some good meteor activity under pretty good observing conditions during several observing nights.
Please enjoy the results:

Remarks
-Lyrid maximum night. Nice rates around local midnight. Decreasing activity before dawn.
-Meteor (sporadic or possible Lyrid) with very bright terminal flare at 2.30 UT in the north.
I- observed two possible earthgrazing Eta Aquarids just before dawn (after radiant check this seems
to be correct).
Long trains,
Michel Vandeputte.
