Régions solaires actives et éruptions solaires

There are five active regions visible on the solar disk. NOAA AR 3599 is decaying in size and complexity (beta-gamma magnetic field configuration), but still producing most of the recent flaring. The strongest flare was a C2.7 that peaked at 18:15 UTC on 12 March, from NOAA AR 3599. More C-class flares are expected, M-class flares are possible.

Éjection de masse coronale

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

Trous coronaux

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 in the next 24 hours.

Vent solaire

The Earth is inside slow solar wind, with speeds close to 430 km/s and an interplanetary magnetic field around 7 nT. The arrival of the high speed stream expected for today may create disturbed conditions. There are low chances of seeing a glancing blow from the 10 March CME.

Géomagnétisme

Geomagnetic conditions were quiet to unsettled both global and locally (NOAA_Kp up to 3 and K_BEL up to 3). A glancing blow from the 10 March CME and a high speed stream could arrive in the next 24 hours and cause up to minor storm levels.

Niveaux de flux de protons

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.

Flux d'électrons sur l'orbite géostationnaire

The greater than 2 MeV electron flux from GOES 16 was below 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.
