Leonids 1999: Observational Results!
The DMS Leonid Expedition 1999 in Spain
Team "València": Image Intensified Video
(Last updated: 31-1-2000)
Many teammembers of the DMS Leonid Expedition 1999 are still
very busy working on the observational materials such as developing films, searching
for meteors, making prints, performing administrative work and so on.
So please have some patience. Thank you!

Image Intensified Video recording of 25 Leonids at station Dos Aguas (222kB!)
25 Leonids captured by the image intensified videosystem of Romke Schievink at station Dos Aguas, Valencia, Spain.
The actual interval lasted for 13 minutes around 2 UT, november 17/18, 1999. This 13 minute interval is compressed into 18 seconds and 25 frames/second.
Some meteors will almost not be recognisable because of the high compression rate.
The two bright stars at top center are Casper and Pollux. The film is played back at twice the normal speed so
meteors move twice as fast. The twinkling of the stars is caused by the strong winds during the recording.
