After reaching solar maximum in Solar Cycle 25, the Sun continues producing multiple solar flares, with some Earth-directed components. Thankfully, those will arrive after Election Day.

It was, however, the strongest this year, beating out an X7.1 flare that erupted earlier this week and an X8.7 flare in May (which Earth dodged).

The X9.0 flare takes the crown from the previous strongest flare of Solar Cycle 25, which was an X8.7 flare on May 14. Thursday's flare is the 15th strongest on record, reports Space Weather Watch.

Such flares, known as coronal mass ejections, are actually fairly common, scientists say. Earth is well protected by both its atmosphere and its magnetic field.
