Mediterranean sprites Oct-Dec + high-speed
From central Catalonia (northeastern Spain) a total of 367 events have been recorded since July 1st till now. In late November and December also a lot of elves. As it turns out, even quite small, low topped thunderstorms can produce sprites and elves. On satellite they look like grey pancakes. A best-of series of images and some videos will appear soon on www.lightningwizard.com, you can find now already some new colour photos of sprites, and lightning.
In early December Joan Montanyà and I (Universitat Politècnica de Catalunya) made our first observations with our Phantom 7.3 high-speed camera with an image intensifier. We operated it from a hill in central Catalonia. We have recorded now 16 elves and 15 sprites at 6688 frames per second or greater during two nights. Here is an example (more will be shown on our site later):
It shows an elve passing through the view, then a long quiet period followed by the developments of a sprite at about 85% into the video.
