Below are a list of selected events that are interesting to view.
The video files that can be downloaded are minimized, and their quality
can not compare with the original.
All sequences shows a view of the sky, looking field-aligned (nearly
vertical), with a field of view of about 10x15 to 25x30 degrees.
North is up in all sequences, if nothing else is mentioned.
The black aurora movie clips, used in a
study of the relative drift between black aurora and the ionospheric plasma,
can also be of interest.

Description:
| Beatiful dynamic rayed aurora.
This sequence was taken pre-Odin, using the
PAI
imager from University of Calgary, Canada,
courtesy Trond S. Trondsen.
During this event, the EISCAT Svalbard Radar
(ESR) observed enhanced ion-acoustic
echoes.

Description:
| Dynamic rayed aurora. The Odin imager was mounted at the
EISCAT Svalbard radar site, and there was a thin cloud cover that
obscures the view slightly. This event also coincides with
ESR observations of enhanced radar echoes. |

Description:
| Same dynamic rayed aurora as above, but this time seen from
another camera (a part of the
SIF facility),
mounted at the Auroral station, 7 km away from the radar.
In this clip, south is up. |

is simultaneous with enhanced ion-acoustic radar echoes.
