The Flare-ometer is at X-level again

[SDO]

Solar flares are classified using the X-ray brightness (see an explanation here (https://spaceweather.com/glossary/flareclasses.html)), and "X class" flares are the strongest. The sunspot and magnetic active region complex that produced many M-class and X-class flares last month is back, and the EVE "flare-ometer" (https://lasp.colorado.edu/eve/data_access/sdo-goes-eve-flare-watch/index.html) is hitting the red zone again.


EVE measures irradiance in the extreme ultraviolet (EUV), which are wavelengths slightly less energetic than X-rays. EUV variations in flux have a direct impact on the Earth's atmosphere and ionosphere, so EVE's measurements are essential for space weather forecasts.

Another X-Flare
June 19, 2025 @ 23:55 UTC
X-Flare Alert. Sunspot region 4114 just produced an X1.9 solar flare peaking at 23:50 UTC (Jun 19). Coronal dimming is not yet evident meaning a noteworthy CME is unlikely. More to follow whenever necessary.
