Space Weather Forecast Discussion

|
| Solar activity was at very low levels. Region 2770 (N23E60, Cso/beta)
remained inactive only producing B-levels enhancements in the X-ray
flux. No Earth-directed CMEs were observed. |
| Solar activity is expected to remain at very low levels for 05-07 Aug. |
|
|
| The greater than 2 MeV electron flux reached moderate levels with a peak
flux of 947 pfu at 04/1740 UTC. The greater than 10 MeV proton flux
remained at background levels. |
| The greater than 2 MeV electron flux is anticipated to reach high levels
on 05-06 Aug and return to moderate levels by 07 Aug. The greater than
10 MeV proton flux is expected to remain at background levels for the
forecast period. |
|
|
| Solar wind parameters reflected the continued influence of a positive
polarity CH HSS. Solar wind speeds remained elevated, yet on the
decline, ending the period near 600 km/s. Total field ranged from 2-5
nT, and the Bz component was +/- 4 nT. Phi was predominantly in a
positive orientation while undertaking brief excursions into a negative
solar sector. |
| Enhanced solar wind conditions are expected to continue on 05
Aug as positive polarity CH HSS effects persist. A gradual return to an
ambient-like, background environment is anticipated for 06-07 Aug. |
|
|
| The geomagnetic field was at quiet to active levels due to CH HSS
effects. |
| Quiet to unsettled conditions, with a slight chance for an isolated
active period, is anticipated for 05 Aug as CH HSS influence persists.
Quiet conditions are expected for 06-07 Aug. |
