   What is a solar flare?

   • A view of a solar flare blasting from the sun in the lower left of the image. (Image credit: NASA/SDO) Solar flares are intense bursts of electromagnetic radiation that originate from sunspots on our sun's surface. They are classified into lettered groups (X, M, C, B and A) according to their size, with X-class flares being the most powerful.

   How do solar X-ray flares affect Earth's ionosphere?

   • Large solar X-ray flares can change the Earth’s ionosphere, which blocks high-frequency (HF) radio transmissions on the sunlit side of the Earth. Solar flares are also associated with Coronal Mass Ejections (CMEs) which can ultimately lead to geomagnetic storms. SWPC sends out space weather alerts at the M5 (5x10 -5 Watts/mw) level.

   What is the strongest solar flare?

   • The biggest event occurred on May 20 with a solar flare later estimated to be an X12 — X-class solar flares are the strongest of several type s — based on data from the Solar Orbiter spacecraft, a joint mission between ESA (European Space Agency) and NASA.

   How powerful is a space flare?

   • The flare was powerful enough that it produced the strongest radiation storm since 2017, according to NOAA's Space Weather Prediction Center (SWPC). These types of events can pose a risk of impact to space launch operations and satellites, and can also disrupt shortwave radio signals.

   1 day ago · The last solar maximum was in 2014; the next is expected around 2025. The chances of seeing the aurora at lower latitudes increase when the sunspot cycle is at a maximum, but chances at higher latitudes are not as dependent on the solar maximum because the auroral oval is normally present.
