Activité solaire

Résumé des dernières 24 heures
Solar activity was at very low levels. No Earth-directed CMEs were observed in available coronagraph imagery.
Prévisions
Solar activity is expected to continue at very low levels on 21-23 Aug.

Particules énergétiques

Résumé des dernières 24 heures
The greater than 2 MeV electron flux reached moderate levels. The greater than 10 MeV proton flux remained at background levels.
Prévisions
The greater than 2 MeV electron flux is expected to be at normal to moderate levels on 21-23 Aug. The greater than 10 MeV proton flux is expected to remain at background levels.

Vent Solaire

Résumé des dernières 24 heures
Solar wind parameters were at mostly nominal levels. Solar wind speeds saw a measured increase over the course of the period, from background levels at the beginning of the period, to just above 400 km/s by periods end. Total field also observed a gradual enhancement to near 10 nT early in the period, before slowly returning to average near 4 nT by the end of the day. The Bz component underwent a maximum southward deflection of -6 nT early in the period, before becoming mostly positive for the remainder of the period. The phi angle was primarily in a negative solar sector.
Prévisions
A predominantly nominal solar wind regime is expected on 21-23 Aug, with weak enhancements possible on 21 Aug associated with potential interaction with a negative polarity CH HSS.

Géospatial

Résumé des dernières 24 heures
The geomagnetic field was quiet.
Prévisions
The geomagnetic field is expected to be mostly quiet on 21-23 Aug, with isolated periods of unsettled levels possible on 21 Aug, due to influence from a negative polarity coronal hole.
