The image below comes from www.spaceweather.com an excellent web site currently also doing noctilucent clouds with some nice images too.

   an enormous swarm of sprites was seen across the top of a thunderstorm in Oklahoma on May 23rd. Note the dendritic upward spreay in the midst of the sprite cluster - that is a possible 'pop through' gigantic jet. It seems a cluster of sprites is capable of warping earth's ionosphere bringing it down from its usual altitude by a considerable distance.
