Sun's Three Years in Three Minutes

In this unusual video, NASA's Solar Dynamics Observatory captures an image of the sun every 12 seconds in 10 different wavelengths, two images per day, for the past three years.

According to NASA:
"There are several noteworthy events that appear briefly in this video. They include the two partial eclipses of the sun by the moon, two roll maneuvers [by the observatory, as it changes position], the largest flare of this solar cycle, comet Lovejoy, and the transit of Venus. The specific time for each event is listed below, but a sharp-eyed observer may see some while the video is playing.” 
They appear at:

00:30:24 Partial eclipse by the moon
00:31:16 Roll maneuver
01:11:02 August 9, 2011 X6.9 Flare, the largest of this solar cycle
01:28:07 Comet Lovejoy, December 15, 2011
01:42:29 Roll Maneuver
01:51:07 Transit of Venus, June 5, 2012
02:28:13 Partial eclipse by the moon"

The music is violinist Martin Lass playing “Our Lady’s Errand of Love.”
