Highlights of Solar and Geomagnetic Activity
29 July - 04 August 2019
Solar activity was very low under a spotless solar disk. Other
activity included a filament eruption observed in SDO/AIA 304
imagery beginning at 04/1640 UTC in the NW quadrant. Analysis is
on-going for any potential coronal mass ejections (CMEs) as
coronagraph imagery becomes available.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was
normal levels during the period.
Geomagnetic field activity ranged from quiet to unsettled levels.
Solar wind parameters indicated the arrival of a co-rotating
interaction region (CIR) preceding a negative polarity coronal hole
high speed stream (CH HSS) beginning midday on 30 Jul. Total field
increased to 11 nT by 30/2024 UTC while solar wind speed increased
to a maximum of 596 km/s at 01/0503 UTC. The geomagnetic field
responded with quiet to unsettled periods on 30 Jul-01 Aug.
Forecast of Solar and Geomagnetic Activity
05 August - 31 August 2019
Solar activity is expected to continue at very low levels for the
forecast period (05-31 Aug).
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach moderate levels on 05 Aug and 18 Aug. High levels
are expected on 06-17 Aug due to CH HSS influence.
Geomagnetic field activity is expected to be reach unsettled to
active levels on 05-08, 10-11, 17-18, 26-28, and 31 Aug with G1
(Minor) geomagnetic storm levels likely on 05-06 Aug due to
recurrent CH HSS effects.
