Solar Activity

.24 hr Summary...
Solar activity was very low.  No Earth-directed CMEs were observed in
available satellite imagery.

Solar activity is expected to remain at very low levels throughout the
forecast period (24-26 Jan).

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached high levels and the greater
than 10 MeV proton flux was steady at background levels.

The greater than 2 MeV electron flux is expected to be at moderate to
high levels for the forecast period (24-26 Jan) due to CH HSS influence.
The greater than 10 MeV proton flux is expected to persist at background
levels throughout the forecast period.

Solar Wind

.24 hr Summary...
Solar wind parameters were slightly enhanced under the waning influences
of a negative polarity CH HSS.  Solar wind speed decreased from
approximately 525 km/s to near 410 km/s.  Total field ranged from 2-5 nT
while the Bz component was between +/-3 nT.  Phi angle was oriented in a
negative sector.

Solar wind parameters are expected to remain enhanced but in gradual
decline on days one and two (24-25 Jan) as the CH HSS continues to wane.
A return to nominal solar wind conditions is expected on day three (26


.24 hr Summary...
The geomagnetic field was at quiet levels.

The geomagnetic field is expected to be at mostly quiet conditions for
the next three days (24-26 Jan). is the U.S. government's official web portal to all federal, state and local government web resources and services.
