Solaktivitet

Sammanfattning av de senaste 24 timmarna

Solar activity was very low. The visible disk remained spotless. No Earth-directed CMEs were observed in available satellite imagery.

Prognos

Solar activity is expected to be very low on 18-20 Feb.

Energirika partiklar

Sammanfattning av de senaste 24 timmarna

The greater than 2 MeV electron flux reached moderate levels. The greater than 10 MeV proton flux remained at background values.

Prognos

The greater than 2 MeV electron flux is expected to reach moderate levels on 18-20 Feb. The greater than 10 MeV proton flux is expected to continue at background levels all three days.

Solvind

Sammanfattning av de senaste 24 timmarna

Solar wind parameters reflected ambient background conditions.

Prognos

Ambient solar wind conditions are anticipated on day one of the forecast period (18 Feb). An enhanced solar wind environment is expected on days two and three (19-20 Feb) due to the anticipated arrival of a recurrent, positive-polarity CH HSS.

Geospace

Sammanfattning av de senaste 24 timmarna

The geomagnetic field was quiet.

Prognos

The geomagnetic field is expected to be mostly quiet on 18 Feb under a nominal solar wind regime. Quiet to active conditions are expected on 19-20 Feb due to the aforementioned recurrent CH HSS.
