These movies
show images taken by the Ultraviolet Imager (UVI) Instrument on
board the POLAR spacecraft. The movies are approximately 0.25
Megabytes each and show a sequenced set of UVI images collected
by the quick-look ground system at the Marshall Space Flight Center
in Huntsville, Alabama. Each movie spans approximately 6 hours
of images. New movies are generated every 6 hours.
The movies are highly compressed, and should not be considered useful for detailed scientific analysis. However, beautiful Earthly aurorae, a result of violent storms on our own sun, should be clearly visible. The left image contains continental outlines, and the right image is a view as seen from above the North Magnetic Pole.
The names of the archived movies are as follows:
yymmddhrmin_UVIaurora.gif
where "yy" is the year (97 and up), "mm" is the month (01 is January), "dd" is the day of month, "hr" is the hour of the day, and "min" is for minute. The times are Central Local Time, and indicate when the movie was made. The actual date of the data, in UT, appears in the movies themselves. The movies are approximately 0.25MB each.
