太陽活動區和耀斑

There are four active regions visible on the solar disk. NOAA AR 3599 is the only one with a complex magnetic field configuration (beta-gamma-delta), and producing most of the recent flaring. The strongest flare was a C3.9, that peaked at 11:35 UTC, from NOAA AR 3599. M-class flares can be expected, X-class flares are possible.

日冕物質拋射

No Earth-directed CMEs were detected in the available coronagraph observations in the last 24 hours.

日冕洞

An equatorial (positive polarity) coronal hole crossed the central meridian on March 10. The high speed solar wind from this coronal hole may arrive at Earth on 13 March.

太陽風

The Earth is inside slow solar wind, with speeds close to 420 km/s and an interplanetary magnetic field around 5 nT. Similar solar wind conditions can be expected over the next 24 hours. A high speed stream and a glancing blow from the 11 March CME will probably create disturbed conditions in the second half of 13 March.

地磁

Geomagnetic conditions were quiet to unsettled (NOAA_Kp up to 3 and K_BEL up to 2). Similar conditions are expected for the next 24 hours. After that, a glancing blow from the 11 March CME and a high speed stream could arrive on 13 March and cause active conditions.

質子通量水平

The greater than 10 MeV proton flux was below the threshold level over the past 24 hours and is expected to remain so for the next 24 hours.

地球靜止軌道上的電子通量

The greater than 2 MeV electron flux from GOES 16 was slightly above the threshold level in the last 24 hours. It is expected to remain below the threshold during the next 24 hours. The 24h electron fluence was at normal level and is expected to remain so.
