Extended Space Weather Discussion:
Solar Activity
.24 hr Summary...
Solar activity was very low. Slight decay was observed in both Regions
2797 (S18W62, Axx/alpha) and 2800 (N18W28, Bxo/beta). No Earth-directed
CMEs were observed.
.Forecast...
Solar activity is expected to be very low on 28-30 Jan.
Energetic Particle
.24 hr Summary...
The greater than 2 MeV electron flux reached high levels with a peak
flux of 3,240 pfu observed at 27/1930 UTC. The greater than 10 MeV
proton flux remained at background values.
.Forecast...
The greater than 2 MeV electron flux is expected to be moderate to high
on 28-30 Jan while the greater than 10 MeV proton flux is expected to
continue at background levels.
Solar Wind
.24 hr Summary...
Solar wind parameters indicated the waning effects of a negative
polarity CH HSS. Solar wind speed decreased from approximately 560 km/s
to near 450 km/s. Total field ranged from 1-6 nT while the Bz component
was between +3/-5 nT. Phi angle was predominantly negative.
.Forecast...
Solar wind parameters are expected to continue to diminish through 28
Jan. A return to nominal solar wind conditions is expected on 29-30 Jan.
Geospace
.24 hr Summary...
The geomagnetic field was quiet to unsettled due to persistent CH HSS
effects.
.Forecast...
The geomagnetic field is expected to be mostly quiet through 30 Jan.
