[00:00:03.780] first starts to cover the Sun
[00:00:06.600] During the partial phases
[00:00:08.240] you must use solar filters or projection techniques
[00:00:11.600] to safely observe the Sun.
[00:00:13.960] It takes about an hour
[00:00:15.840] for the moon to completely cover the Sun.
[00:00:19.480] The last bit of the Sun is the "diamond ring".
[00:00:23.840] "Second Contact" - Totality!
[00:00:26.200] "Third contact"! Put back on your filters!
[00:00:30.240] The last hour the moon gracefully exits, uncovering the Sun.
[00:00:40.220] As the last bit of the moonleaves the Sun,
[00:00:44.520] it is "Fourth contact"
[00:00:46.600] and the end of the eclipse.
