<<Below are a couple of videos: even though you are not supposed to look directly at the Sun during an eclipse, the PROBA-2 satellite
did with an awesome result, and astronaut Don Pettit’s exceptional view of the eclipse from the International Space Station:
<<ESA’s space weather microsatellite Proba-2 observed the solar eclipse on the evening of May 20, 2012. It passed through the Moon’s shadow a total of four times, imaging a sequence of partial solar eclipses in the process. The first contact was made on Sunday May 20 at 21:09 GMT. The last contact finished at 03:04 GMT.>>
An amazing timelapse video by Cory Poole was made from 700 photographs taken with a Coronado Solar Max 60 Double Stack telescope. Usually, the chromosphere can’t usually be seen due to the overwhelming brightness of the photosphere, and to see it requires special equipment. Thankfully, Poole has it: “The Telescope has a very narrow bandpass allowing you to see the chromosphere and not the much brighter photosphere below it,” Poole wrote on YouTube. Additionally, the special hydrogen alpha filter Poole used “only allows light that is created when hydrogen atoms go from the 2nd excited state to the 1st excited state.”
The chromosphere is the red circle around the outside of the Sun; its red coloring is caused by the abundance of hydrogen. Watch how the chromosphere appears along the outline of the Moon, too!
