Actividad solar

Resumen 24 hr
Solar activity was very low. The visible disk was spotless. No Earth-directed CMEs were observed in available satellite imagery.
Predicción
Solar activity is expected to remain very low on 25-27 Feb.

Partículas Energéticas

Resumen 24 hr
The greater than 2 MeV electron flux reached moderate levels. The greater than 10 MeV proton flux remained at background values.
Predicción
The greater than 2 MeV electron flux is expected to be at moderate to high levels on 25-27 Feb due to elevated solar wind speeds. The greater than 10 MeV proton flux is expected to continue at background values.

Viento Solar

Resumen 24 hr
Solar wind parameters reflected a return to near-background conditions. Solar wind speeds showed a downward trend, ending the day at or below 400 km/s. Total field was at or below 5 nT, and Bz was unremarkable. Phi angle was mostly negative.
Predicción
The solar wind environment may become enhanced again on 26-27 Feb. Recurrence suggests an enhancement is likely from a negative polarity, south polar extension CH HSS, although this feature is less apparent this rotation.

Geoespacio

Resumen 24 hr
The geomagnetic field was quiet.
Predicción
The geomagnetic field is expected to be mostly quiet on 25 Feb, then become unsettled through 27 Feb with possible CH HSS (negative polarity) activity. There is a slight chance for active conditions on 26-27 Feb as well if this feature becomes geoeffective.
