Three X-class Solar Flares in 24 Hours
Not everyday do we get to see three X-class solar flares in less than 24 hours. And because we have never been able to observe the Sun with so many sophisticated instruments, we love sharing the various views.
This is seen through the AIA 304 angstroms wavelength. This channel sees the chromosphere and lower transition region of the Sun in extreme ultraviolet. The temperatures seen here are approx. 90,000 F.
It starts off with the X1.7 flare, then the X2.8 and ends with the X3.2-class solar flare.
