Solar flares measured around X1 — like the May 13 and 14 events — indicate strong flare intensity. An X10 flare is described as as a severe event, according to NOAA.

Within the next couple of days, solar activity associated with the flare could also produce auroras as far south as New York in the East and Idaho in the West, forecasters said.

This flare was categorized as an X2.8 flare. The X indicates the class of flare, with X being the strongest and other less powerful classes being A, B, C, and M.The 2.8 number indicates the power ...

A blazing X2.7-class solar flare erupted from sunspot AR4087 early Tuesday, hurling a scorching wave of plasma and charged particles straight at Earth. NASA/SDO.

The flare had a magnitude of at least X9, making it the most powerful solar eruption of the current solar cycle — surpassing a monster X8.7 magnitude blast in May.

(NEXSTAR) — A massive solar flare — the largest in years — was spotted on the sun on New Year’s Eve, sparking a warning to some high-frequency radio users.

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.

Solar flares are categorized into flare classes, classified by the magnitude of soft X-rays observed in a narrow wavelength range of 0.1-0.8 nm. The flare classes are C-class, M-class and X-class ...
