16-17 and 17-18 December 2007: Sprites & Elves
Some sprites were so small that the software only triggered on the lightning flash, and thus one may expect these would otherwise be missed.
16-17 December events:
- Halo only: 3
- Elve: 7
- Sprite (normal): 17
- Sprite (otherwise undetected): 7
Here are some images:
Another big event with a halo inside:
17-18 December events:
- Halo only: 1 (but several simultaneous with sprites)
- Elve: 6
- Sprite (normal): 16
Another elve, with slightly irregular patterns of luminosity:
One from my balcony in Toulouse (camera set up only very late). Unfortunately outside the view of the camera at Lannemezan. My camera gives a less noisy but also less bright image because the gain is manually controlled and here I used also gamma=off.
and a Very Happy 2008!
