Tomorrow, May 20th, we will have an annular solar eclipse. An annular eclipse is one where the moon isn’t quite big enough to block out the entire sun, so the maximum eclipse has a ring of sun showing around the moon. The tail end of the eclipse will be visible in the Southwestern United States at around 7:30pm Mountain Time. Unfortunately for those of us in Colorado, it appears that we’re going to just miss it. The maximum eclipse is at 5:53pm MDT, when the eclipse shadow will be somewhere over the Pacific Ocean. The linked article has pictures showing where and when the eclipse will be visible—the times are in UTC, which is 6 hours ahead of Mountain Daylight Time.
Thanks to Josh for this topic.
Update: The path shown in the linked article is where the ring eclipse will be visible. A partial eclipse can be seen from a much larger area. So if you know how to safely view an eclipse, you should be able to see the partial eclipse from much of the Western United States.
Update #2: Josh writes: “I was doing some online research and apparently http://events.slooh.com/ is doing some sort of broadcast of the eclipse from various locations along the line of annularity (via Huffington Post)”.
