ARLA/CLUSTER: Gigantescas descargas electricas sobre os E. U. A.

[João Costa > CT1FBF]

Gigantic sprites appear over the USA

This week, backyard photographers have been observing gigantic red sprites
flickering over the USA.

These electrical discharges, which occur high above thunderclouds, resemble
enormous jellyfish and their glow can often be seen hundreds of miles away.

A specimen highlighted on today's edition of Space Weather would dwarf Mt.
Everest.
