The Sun emitted a significant solar flare peaking at 11:35 a.m. EDT on Oct. 28, 2021. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.
Solar flares are powerful bursts of radiation. Harmful radiation from a
flare cannot pass through Earth’s atmosphere to physically affect humans on the
ground, however — when intense enough — they can disturb the
atmosphere in the layer where GPS and communications signals travel.
This flare is classified as an X1-class flare.
X-class denotes the most intense flares, while the number provides more
information about its strength. An X2 is twice as intense as an X1, an X3 is
three times as intense, etc. Flares that are classified X10 or stronger are
considered unusually intense.

extremely hot material in flares and which is colorized here in teal. Credit:
