Boing Boing reader Cory Poole is a 33-year-old math and science teacher at University Preparatory School in Redding, CA. He sends in this beautiful video of yesterday's annular solar eclipse, and says:
This is a 60 second time-lapse video made from 700 individual frames through a Coronado Solar Max 60 Double Stacked Hydrogen Alpha Solar Telescope. The pictures were shot in Redding, CA, which was directly in the annular eclipse path. The filter on the telescope allows you to see the chromosphere which is a layer that contains solar prominences. The filter only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state.
On May 20-21 (this coming Sunday night through this coming Monday morning), sky-watchers in Asia and much of the U.S. will be able to view a “ring of fire” eclipse or a partial eclipse of the Sun, depending on their location. The rest of the world, including our readers along the East Coast of the US, will have to settle for viewing this special celestial event online.
The shadowandsubstance.com astronomy website has a totally awesome animated map showing how the eclipse will look to viewers in each U.S. state. But more importantly, he gives the best eclipse advice you'll get anywhere:
The safest way to view this event is to attend a planetarium, observatory or local astronomy club on May 20th.
Here's an index of astronomy clubs around the world.
For DIYers, a pinhole projector is another option.
