Aurora videos

All videos are 8x speeded up; normal speed in these displays would have been totally boring. Only MPG-files have been posted. Usually I use RM-format to save space and also to shorten downloading times, but with auroras the quality would have been degraded too much.
Current MiniDV-camcorders are in the very limit to record auroras; simultaneous moonlight will help to keep noise reasonable, but still 1/3 second exposure and +6 - +12 dB gain is required with iris fully open at f=1.6. Camera used for auroras is Sony VX2000. The newer (professional) model DSR-PD170 didn't give any better result in spite of the advertised better sensitivity of the CCD.
