Highlights of Solar and Geomagnetic Activity
02 - 08 September 2019
Solar activity was at very low levels. Region 2748 (N14, L=205,
class/area Hsx/020 on 02 Sep) was quiet and stable and decayed to
plage on 03 Sep. No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
very high levels on 02-04 Sep and high levels on 05-08 Sep. Electron
flux reached a maximum of 87,900 pfu at 04/1835 UTC.
Geomagnetic field activity ranged from quiet to G1 (minor) storm
levels on 02 Sep due to effects from a large, recurrent, positive
polarity CH HSS. From 03-06 Sep, quiet to active levels were
observed as HSS effects continued. Quiet to unsettled levels were
observed from 07-08 Sep. Wind speeds began the period near 750 km/s,
but slowly decayed to end the period near 400 km/s.
Forecast of Solar and Geomagnetic Activity
09 September - 05 October 2019
Solar activity is expected to be at very low levels.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels from 09-13 Sep, and again from 27 Sep
- 06 Oct due to HSS effects. Normal to moderate levels are expected
on 14-26 Sep.
Geomagnetic field activity is expected to be at mostly quiet levels
on 09-26 Sep. Isolated unsettled periods are possible on 23, 26 and
30 Sep, and 01-03 Oct. G1 (minor) to G2 (moderate) geomagnetic storm
levels are likely on 27-29 Sep due to positive polarity CH HSS
effects.
