Solar Activity

.24 hr Summary...
Solar activity was at very low levels.  Slight Decay was observed in
Region 2696 (S13E05, Dro/beta).  No Earth-directed CMEs were observed in
available satellite imagery.

Solar activity is expected to remain at very low levels throughout the
forecast period (17-19 Jan).

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached moderate 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 normal to
moderate levels throughout the forecast period (17-19 Jan).  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 at nominal levels over the period.  Solar
wind speed declined from approximately 430 km/s to near 340 km/s.  Total
field ranged from 1-6 nT while the Bz component was between +5/-3 nT.
Phi angle was oriented in a predominantly positive (away) sector.

Solar wind parameters are expected to be near nominal levels for the
next three days (17-19 Jan).


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

The geomagnetic field is expected to be mostly quiet for the next three
days (17-19 Jan), with isolated periods of unsettled conditions on day
three. is the U.S. government's official web portal to all federal, state and local government web resources and services.
