太陽活動區和耀斑

Solar flaring activity was moderate over the past 24 hours. The largest flare was a M1.3-flare, with peak time 09:36 UTC on August 19, from NOAA AR 3785 (beta). There are currently 10 numbered active regions on the visible disk. NOAA AR 3784 is the most complex AR (beta-gamma-delta). The solar flaring activity is expected to be at moderate levels over the coming day with C-class flares expected and M-class flares probable and a low chance of X-class flares.

日冕物質拋射

No new Earth-directed Coronal Mass Ejections (CMEs) have been detected in the available coronagraph images.

日冕洞

A positive polarity low-latitude coronal hole crossed the central meridian. A high-speed stream from this coronal hole may enhance the solar wind environment near Earth on August 22.

太陽風

The solar wind at the Earth is slow, with speeds around 400 km/s and interplanetary magnetic field around 7nT, with the Bz reaching a minimum value of -5 nT. Slow solar wind conditions are expected to continue in the next 24h.

地磁

Geomagnetic conditions were globally and locally quiet to active (Kp 4- and K Bel 4). Quiet conditions are expected in 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 background levels and is expected to remain so over the next days.

地球靜止軌道上的電子通量

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