Solar Activity

.24 hr Summary...
Solar activity was at very low levels.  Region 2459 (N04E33, Cao/beta)
produced the largest flare of the period, a B4 flare at 27/1342 UTC.
Despite being the most active region on the disk, Region 2459 showed
slight decay in spot number and magnetic complexity.  The other regions
on the disk were either stable or in decay and inactive.  No
Earth-directed coronal mass ejections were observed in available
coronagraph imagery.

Solar activity is expected to be at very low levels with a slight chance
for C-class flares for the next three days (28-30 Nov).

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at normal levels while the
greater than 10 MeV proton flux remained at background levels throughout
the period.

The greater than 2 MeV electron flux is expected to be at normal to
moderate levels over the next three days (28-30 Nov).  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 measured by the ACE spacecraft reflected minor
enhancements.  Total magnetic field strength was predominantly in the
6-9 nT range throughout the period.  The Bz component started the period
in a southward direction reaching a maximum deflection of -9 nT.  After
27/0400 UTC, Bz began to oscillate between -4 nT and +4 nT.  Wind speeds
were relatively low between 270 km/s and 320 km/s.  Phi angle was
positive (away) to begin the period and rotated into the negative
(towards) sector after 27/0400 UTC.

Solar wind parameters are expected to reflect near background levels on
days one through three (28-30 Nov).


.24 hr Summary...
The geomagnetic field was mostly quiet with an isolated period of
unsettled in response to a minor enhancement in solar wind parameters
early in the period.

The geomagnetic field is expected to be at quiet levels with isolated
periods of unsettled conditions on days one through three (28-30 Nov)
due to minor enhancements in the solar wind. is the U.S. government's official web portal to all federal, state and local government web resources and services.
