Solar Activity

.24 hr Summary...
Solar activity was very low. Regions 3151 (S16W73, Cso/beta) and 3152
(N27W05, Bxo/beta) were stable and in decay.

A filament/prominence eruption occurred from along the southeast limb
beginning near 28/2049 UTC as seen in GOES/SUVI 304A imagery. This event
was modeled and determined to be a clear miss.

.Forecast...
Solar activity is expected to be very low with a chance for C-flares
through 01 Dec.

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux reached moderate levels. The
greater than 10 MeV proton flux was at background levels.

.Forecast...
The greater than 2 MeV electron flux is expected reach high levels on 29
Nov with elevated solar winds and the greater than 10 MeV proton flux is
expected to persist at background levels.

Solar Wind

.24 hr Summary...
Earth remained under the influence of a positive polarity CH HSS. Solar
wind speeds started the day around 540 km/s and increased to near 660
km/s. Total field strength peaked at 9 nT and Bz deviated southward
early and late in the day, reaching a maximum southward deviation of -10
nT at 28/0033 UTC.

.Forecast...
An enhanced solar wind environment is expected to last through 01 Dec
due to the influences of multiple positive polarity CH HSSs.

Geospace

.24 hr Summary...
The geomagnetic field reached G1 (Minor) geomagnetic storming levels
while under the influence of a positive polarity CH HSS.

.Forecast...
Unsettled to active conditions are expected through 29 Nov with ongoing
CH HSS (+) activity, along with the anticipated arrival of another
positive polarity CH HSS. Isolated G1 (Minor) storming is also possible.
A third CH HSS is forecast to arrive on Day 3 (01 Dec) with stronger
winds, prompting a G1 (Minor) geomagnetic storm Watch.
