A few years ago I saw a TV program about the Sun, they had an extraordinary time-lapse movie from the Japanese Solar observatory Yohko of one complete Solar Cycle from about 1991 onwards - has anyone seen this video online and downloadable anywhere?
Start here:

Also google "YPOP". I doubt there is much activity by that group anymore, but I know they've had copies of what you're looking for.
