Solar Activity

.24 hr Summary...
Solar activity was at very low levels.  Region 2457 (N12W40, Hax/alpha)
produced the largest flare of the period, a B6 at 28/1134 UTC.  All of
the spotted regions on the disk were either stable or in decay during
the period.  No Earth-directed coronal mass ejections were observed in
available coronagraph imagery.

Solar activity is expected to be at very low levels with a chance for
C-class flares over the next three days (29 Nov-01 Dec).

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 (29 Nov-01 Dec).  The greater
than 10 MeV proton flux is expected to persist at background levels for
the forecast period.

Solar Wind

.24 hr Summary...
Solar wind parameters were at mostly ambient levels with slightly
enhanced magnetic field strength.  Solar wind speeds gradually increased
from near 320 km/s to about 350 km/s by periods end.  Total field
strength (Bt) was slightly elevated between 8 nT and 14 nT.  The Bz
component was variable and ranged from 10 nT to -11 nT.  Phi angle was
oriented in a negative (towards) sector.

Nominal conditions are expected through late on day two (29-30 Nov).
Late on day two into day three (30 Nov-01 Dec), arrival of a co-rotating
interaction region (CIR) and subsequent coronal hole high speed stream
(CH HSS) is expected to cause enhancements in the solar wind


.24 hr Summary...
The geomagnetic field was mostly quiet with an isolated period of
unsettled conditions.

The geomagnetic field is expected to be at quiet to unsettled levels
through late on day two (28-29 Nov).  By late on day two, a positive
polarity CH HSS is expected to become geoeffective causing unsettled to
active periods.  Active to G1 (Minor) storm conditions are expected on
day three (01 Dec) due to continued CH HSS effects. is the U.S. government's official web portal to all federal, state and local government web resources and services.
