太陽活動

24小時內評估
Solar activity reached high levels as a result of AR3590 (N18E26, Fkc/beta-gamma-delta) producing an X6.3/3b flare at 22/2234 UTC, which is this largest flare of this solar cycle. A tenflare of 240 SFU was associated with this event and peaked at 22/2225 UTC. No resulting CME was observed in coronagraph imagery. New Region 3591 (S34E77, Hsx/alpha) produced an M1.5 flare at 22/0014 UTC. Regions 3592 (S12E78, Dso/beta)and 3593 (S04W58, Bxo/beta) were numbered this period and were mostly inactive. No Earth-directed CMEs were observed.
預測
High solar activity is expected to continue through 25 Feb with M-class flares being likely, and a chance for X-class flares due to the recent history of ARs 3590 and 3591.

高能粒子

24小時內評估
The greater than 10 MeV proton flux was at near-background levels. The greater than 2 MeV electron flux was at normal to moderate levels.
預測
There is a slight chance for an S1 (Minor) proton event for the next three days (23-25 Feb) due primarily to the potential of AR3590. The greater than 2 MeV electron flux is expected to continue at normal to moderate levels.

太陽風

24小時內評估
The solar wind environment was at nominal levels. Total field strength peaked at 7 nT and Bz was variable. Wind speeds averaged near 325 km/s. Phi switched from positive to negative around 23/0900 UTC.
預測
Nominal levels are expected through 24 Feb. CME and CH HSS influences are forecast for 25 Feb. The bulk of the CME is expected to pass ahead of Earths orbit.

近地太空

24小時內評估
The geomagnetic field remained at quiet levels while the IMF returned to background levels.
預測
Mostly quiet conditions are anticipated through 24 Feb. G1 (Minor) storm levels are likely to be reached on 25 Feb with combined effects of the 21 Feb CME (filament eruption) and a CH HSS.
