Highlights of Solar and Geomagnetic Activity 04 - 10 August 2014
Solar activity was at low levels throughout the period. The largest event of the period was a C4/1n flare on 08 Aug at 1701 UTC from Region 2135 (N11, L=129, class/area=Dho/250 on 08 Aug). Regions 2130 (S07, L=229, class/area=Dkc/290 on 31 Jul) and 2132 (S21, L=212, class/area=Eac/230 on 08 Aug) produced only low-to-mid level C-class flare activity and were the most prominent regions of this period.
No Earth-directed coronal mass ejections (CMEs) were observed this period, however, a far-sided full-halo CME was observed in SOHO LASCO coronagraph imagery between 1555-1636 UTC on 08 Aug. This CME was associated with flare activity from old Region 2126 (S09, L=327).
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at normal levels on 04-05 Aug with normal to moderate levels observed on 06-10 Aug, reaching a maximum flux value of 908 pfu at 1640 UTC on 07 Aug.
Geomagnetic field activity was at quiet levels on 07 and 09 Aug with quiet to unsettled levels observed on 04-06, and 08 Aug. Quiet conditions with an isolated period of active conditions (1800-2100 UTC) were observed on 10 Aug, with the active period resulting from the influence of a negative polarity coronal hole high speed steam.
Forecast of Solar and Geomagnetic Activity 11 August - 06 September 2014
Solar activity is expected to be low throughout the outlook period.
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 for 12, 14-21, 23, 25-27, 30 Aug , and 03-05 Sep. Quiet to unsetteld conditions are expected for 11, 13, 22, 24, 28-29 Aug, 01-02, and 06 Aug due to weak influence from coronal hole high speed streams (CH HSS). Quiet to active conditions are expected for 31 Aug due to moderate CH HSS effects.
