Forecast of Solar and Geomagnetic Activity
18 August - 13 September 2014

Solar activity is expected to be low throughout the period with a
slight chance for M-class (R1-R2 (Minor-Moderate)) flare activity
for 21 Aug - 06 Sep due to the return of old Regions 2127 (S09,
L=249, class/area=Dkc/300 on 30 Jul) and 2130 (S07, L= 230,
class/area=Ekc/290 on 01 Aug), which produced one and two M-class
flares, respectively.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal to moderate levels throughout the outlook
period.

Geomagnetic field activity is expected to be quiet on 18, 23-27, and
30 Aug, 03-05 and 09-13 Sep. Quiet to active conditions are expected
on 19-20 Aug due to the anticipated arrival of the 15 Aug coronal
mass ejection (CME), followed by quiet to unsettled conditions on
21-22 Aug due to coronal hole high speed stream (CH HSS) effects.
Quiet to unsettled conditions are expected on 28-29 Aug due to a
solar sector boundary crossing followed by a co-rotation interaction
region. Quiet to active conditions are expected on 31 Aug followed
by quiet to unsettled levels on 01-02 Sep due to CH HSS effects.
Quiet to unsettled levels are expected on 06-08 Sep due to CH HSS
effects.
