Wow
It might be a dance party of sprites .
It seems you built nice 360 degree observation system.

Very nice, especially those big ones!
Yes 50 sprites in a night is a lot, but in the USA where there are regularly very large storms it may be more common. Researcher Walt Lyons in Colorado has had nights with hundreds of sprites.
Here in Europe some systems produce like 60 sprites once in a while. More typical is 10-30. I had once 77 sprites. Elve nights can be prolific as well with 50-100 events per night over small winter thunderclouds. But this year my area (northeastern Spain) had almost no storms, very unusual. It seems all activity went to the eastern Mediterranean Sea.
However, we broke the record number of sprites in a night for Europe: on 28-29 November 2011 our camera on Pic du Midi recorded 140 events, mainly sprites, over a storm near the coast of Algeria all night long. It is possible that Sahara dust somehow enhanced the electrification of the storm. Expressed in hourly rates the numbers aren't so unusual, though.

Hi Oscar,
Thanks for sharing your information. Then, our observation is
just a tip of the iceberg. We might expect more of such an sprite storm!
Very encouraging!!
Taka
