Attività solare

Sommario di 24 ore

Solar activity reached moderate levels following an M2.5 flare (R1-Minor) at 16/0435 UTC from a source beyond the east limb. All five active regions on the disk were stable throughout the period. No Earth-directed CMEs were detected in available imagery.

Previsione

Solar activity is expected to be at low levels, with a slight chance for M-class (R1-R2/Minor-Moderate) flares through 18 Feb.

Particelle energetiche

Sommario di 24 ore

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

Previsione

The greater than 2 MeV electron flux is expected to reach moderate levels on 16 Feb, before increasing to high levels on 17-18 Feb. The greater than 10 MeV proton flux is expected to continue at background levels through 18 Feb.

Vento Solare

Sommario di 24 ore

Solar wind parameters were consistent with positive polarity CH HSS influences. Total magnetic field strength reached a peak of 9 nT. The Bz component ranged between +8/-7 nT. Solar wind speeds slowly decreased from a peak of around 750 km/s early in the period to around 550-600 km/s by the end of the period. The phi angle was predominantly positive.

Previsione

The solar wind environment is expected to remain enhanced through 18 Feb due to continued, but weakening CH HSS influences.

Geospaziale

Sommario di 24 ore

The geomagnetic field reached active levels in response to positive polarity CH HSS influences.

Previsione

Isolated periods of G1 (Minor) geomagnetic storming are likely on 16 Feb due to positive polarity CH HSS influences. Active conditions are likely on 17 Feb, with quiet to unsettled levels likely on 18 Feb, as CH HSS influences wane.
