Solar Activity

.24 hr Summary...
Solar activity was at very low levels. Region 2427 (N18W52, Dao/beta)
remains the only region on the disk and produced a single B-class flare.
The region showed decay in its intermediate and trailer spots. No CMEs
were detected by SOHO LASCO C2 imagery.

Solar activity is expected to be very low with a chance for C-class
flares for the forecast period (05-07 Oct).

Energetic Particle

.24 hr Summary...
The greater than 2 MeV electron flux was at predominately normal to
moderate levels but reached high levels at the end of the period. The
greater than 10 MeV proton flux remained at background levels.

The greater than 2 MeV electron flux is expected be at normal to
high levels all three days of the forecast period (05-07 Oct). The
greater than 10 MeV proton flux is expected to remain at background
(Below S1-Minor) levels.

Solar Wind

.24 hr Summary...
Solar wind parameters remained slightly enhanced throughout the period.
Solar wind speeds averaged about 500 km/s. Total field strength (Bt)
ranged between 5-10 nT while the Bz component varied between -7 to
+6 nT. The phi angle remained in a steady positive (away from the Sun)
orientation with a short variation to a negative orientation between
approximately 04/2000-2200 UTC.

Solar wind parameters are expected to remain slightly enhanced on day
one (05 Oct) with a slow return to nominal levels through days two and
three (06-07 Oct).


.24 hr Summary...
The geomagnetic field was at quiet to minor storm (G1) levels due to
substorming and prolonged negative Bz.

The geomagnetic field is expected to be at quiet to active levels,
with possible isolated minor storm periods, for the remainder of day one
(05 Oct). Predominately quiet to unsettled levels are expected on days
two and three (06-07 Oct). is the U.S. government's official web portal to all federal, state and local government web resources and services.
