Solar Activity 24 hr summary
Solar activity was very low. No Earth-directed CMEs were observed in coronagraph imagery.
Solar Activity Forecast
Solar activity is expected to be at very low levels on 21-23 Jan.
Energetic Particle 24 hr summary
The greater than 2 MeV electron flux was below alert threshold values, and the greater than 10 MeV proton flux continued at background values.
Energetic Particle Forecast
The greater than 2 MeV electron flux is expected to continue at normal to moderate levels on 21 Jan. Moderate to high levels are possible on 22-23 Jan with possible arrival of a weak, negative polarity CH HSS. The greater than 10 MeV proton flux is expected to remain at background levels.
Solar Wind 24 hr summary
Solar wind parameters were at background levels. Phi angle was predominantly negative.
Solar Wind Forecast
The solar wind environment could become enhanced on 21-22 Jan with the possible arrival of a weak, negative polarity CH HSS. Otherwise mostly quiet conditions are anticipated for the next three days (21-23 Jan).
Geospace 24 hr summary
The geomagnetic field was quiet.
Geospace Forecast
The geomagnetic field is expected to be at mostly quiet to unsettled levels through 22 Jan with possible influence from a weak, negative polarity CH HSS. An isolated active period (Kp=4) is possible if this feature becomes geoeffective. Mostly quiet conditions can be expected by 23 Jan.
