太陽活動區和耀斑

There are ten visible active regions on the solar disk. Mostly C-class flaring has been observed in the last 24 hours, from NOAA ARs 3319 and 3323. Nevertheless, there was one M-class flare from NOAA AR 3324: M1.5 peaking at 02:41 UTC. NOAA AR 3315 which caused many flares this week is now rotating out of view over the west limb. More M-class flares can be expected and X-class flares are possible.

日冕物質拋射

No Earth-directed coronal mass ejections (CMEs) were detected in the past 24 hours.

日冕洞

There are two positive polarity coronal holes, a small close to the equator and another one in the south. The solar wind from these coronal holes may still affect the Earth today.

太陽風

In the last 24 hours we saw the passage of a mild high speed stream, speeds up to 500 km/s and interplanetary magnetic field up to 9 nT. Since there are two (small) coronal holes visible, we may still some increases in solar wind speed today. Otherwise, over the next 24 hours we expect a return to slow solar wind.

地磁

The geomagnetic conditions over the past 24 hours reached active levels locally (K_Belgium up to 4) and moderate at planetary scale (Kp up to 3). Moderate to active periods can be expected for the next 24 hours.

質子通量水平

Over the past 24 hours the greater than 10 MeV GOES proton flux was at nominal levels and is expected to remain so in the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux was below the 1000 pfu threshold over the past 24 hours and is expected to remain so in the next 24 hours. The 24h electron fluence was at normal levels and is expected to remain at normal levels over the next 24 hours.
