A Week Filled with Flares
During the week of Friday, August 12, to Thursday, August 18, 2022, the Sun was particularly busy. Several bright active regions were present, and starting on the 15th, they were responsible for 11 Mclass flares. Mclass flares are one level below Xclass, the highestenergy designation. This imagery is all captured by the Solar Dynamics Observatory in the 171angstrom wavelength of extremeultraviolet light. This wavelength is particularly good at showing loop structures in the Sun s corona, or atmosphere. At times, the image of the Sun disappears from view. SDO is in a geosynchronous orbit and occasionally Earth gets in between SDO and the Sun, blocking the view. Careful observation will reveal a fuzzy edge to the blackness that travels across the solar disk. This is Earth s atmosphere. Music: Rhombus from Geometric Shapes.
