camillaspacechicken A look at today's Sun. The red 304 angstroms view is at 50,000 degrees K and the turquoise 131 angstroms is at 10,000,000 degrees K. Today alone we have had 8 M-class solar flares. How exciting to be a solar observing spacecraft! #NASA #SDO #Sun #SpaceWeather #Space #Astronomy 4y
