Solaktivitet

Sammanfattning av de senaste 24 timmarna

Solar activity was very low. No Earth-directed CMEs were observed in coronagraph imagery.

Prognos

Solar activity is expected to be at very low levels on 22-24 Jan.

Energirika partiklar

Sammanfattning av de senaste 24 timmarna

The greater than 2 MeV electron flux was below alert threshold values, and the greater than 10 MeV proton flux continued at background values.

Prognos

The greater than 2 MeV electron is expected to be at moderate to high levels on 22-24 Jan with CH HSS activity. The greater than 10 MeV proton flux is expected to remain at background levels.

Solvind

Sammanfattning av de senaste 24 timmarna

The solar wind environment became enhanced early in the UTC day with the onset of a weak, negative polarity CH HSS. Total field peaked at 9 nT with arrival, and Bz periodically deviated southward in excess of -5 nT for short intervals. Solar wind speeds increased from around 275 km/s to around 350 km/s with this feature. Phi was predominately negative.

Prognos

CH HSS effects are expected to continue into 22 Jan. Thereafter a return to nominal, background solar wind conditions is expected.

Geospace

Sammanfattning av de senaste 24 timmarna

The geomagnetic field was mostly quiet, with an unsettled period later in the period due to the weak CH HSS (negative polarity).

Prognos

The geomagnetic field is expected to be at mostly quiet to unsettled levels through 22 Jan with ongoing CH HSS activity. An isolated active period (Kp=4) is also possible. Mostly quiet conditions can be expected by 23 Jan through 24 Jan.
