X1.1 solar flare
Friday, 28 March 2025 18:06 UTC
We have only just started to relax following the moderate G2 geomagnetic storm conditions from a massive coronal hole and suddenly... bam... our Sun surprises us all with a X1.1 solar flare (R3-strong) that came from sunspot region 4046 which is just rotating into view on the east limb.
The eruption is visually stunning as the flare is associated with a filament eruption and it is easy to see that it launched a large coronal mass ejection into space. This is clearly visible on this animation provided by GOES-16 and the familiar coronagraph imagery from SOHO/LASCO. The coronal mass ejection is of course not aimed at Earth due to the location of the eruption at or near the east limb but for sure this region is something to keep an eye on in the days ahead.
