太陽活動區和耀斑

There are two active regions visible on the disk. The strongest flare was an M1.2 from an unnumbered region on the east limb, peaking at 05:42 UTC. More M-class flares are possible in the next 24 hours.

日冕物質拋射

No Earth directed CMEs were observed in the last 24 hours.

日冕洞

Two coronal holes crossed the central meridian in the past 24 hours, one with negative polarity at high northern latitudes and an equatorial one with positive polarity.

太陽風

The Earth is immersed in slow solar wind, over the last 24 hours solar wind speed has decreased to 300 km/s and the interplanetary magnetic field is around 5 nT. Same conditions are expected for the next 24 hours.

地磁

During the last 24 hours the geomagnetic conditions were quiet globally and locally (NOAA KP 1, K_Bel 1). Mostly quiet conditions are 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 below threshold and is expected to remain so over 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, as measured by GOES 16. It is expected to remain so in the next 24 hours. The 24 hour electron fluence was at normal levels, it is expected to stay at those levels for the next 24 hours.
