Solar Activity Is Heating Up - February 10. 2024.

Solar activity reached high levels due to a X3.3 flare at 09/13:14 UTC from old Region 3575 from just beyond the SW limb. Associated with this event was a 1,000 sfu Tenflare, a Type IV radio sweep and a partial-halo CME off the SW limb beginning at 09/13:25 UTC. The CME is not expected to have any Earth-directed component given its position beyond the SW limb. An eruption registering as an M3.4 solar flare was observed off the southeast limb at 03:54 UTC (Feb 10). A large coronal mass ejection (CME) is also seen in updated LASCO imagery. Because this is yet another limb event, it too should be directed away from Earth. Glancing Blow CME A filament eruption beginning at 08/20:00 UTC was reanalyzed. A likely associated CME was observed off the S limb at 09/01:54 UTC in SOHO/LASCO C3 imagery. Modelling results indicated the potential for a grazing blow mid to late on 12 Feb. Radiation Storm in Progress A “snow storm“ is underway in the latest SOHO/LASCO coronagraph imagery. This is caused by energetic particles bombarding the detectors onboard the spacecraft. A minor (S1) radiation storm continues and it could persist into Sunday. The increased particle levels is also causing a disturbance known as a polar cap absorption event (PCA). The main effect would be a degradation of HF signals through the polar zones, especially at lower frequencies.
