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.
