Today's eclipse, where Earth moves once again between the SDO spacecraft and the Sun, started at 06:09 UT and ended at 07:20 UT. This movie shows the event in two different wavelengths. 304 angstroms first, which shows the approx. 50,000 degrees C. Chromosphere and the second segment is 171 angstroms, which shows the 1 million degrees C. transition region between the Chromosphere and the Corona.
