Highlights of Solar and Geomagnetic Activity
29 January - 04 February 2018
Solar activity was at very low levels from 29 Jan - 03 Feb. Low
levels were observed on 04 Feb as new Region 2699 (S04, L=171,
class/area Hsx/080 on 04 Feb) produced a C1 flare at 04/2024 UTC.
The region also produced numerous B-class flares after rotating onto
the disk. No Earth-directed CME activity was observed during the
period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at
moderate levels on 29 Jan with a peak flux of 130 pfu observed at
29/0005 UTC. Normal levels were observed from 30 Jan - 04 Feb.
Geomagnetic field activity was at mostly quiet levels with isolated
unsettled intervals observed early on 30 Jan and again late on 31
Jan.
Forecast of Solar and Geomagnetic Activity
05 February - 03 March 2018
Solar activity is expected to be to be at mostly very low levels
with a slight chance for low activity through 16 Feb due to the
emergence of Region 2699. Very low levels are anticipated from 17-28
Feb after the departure of Region 2699. A slight chance for low
levels is possible from 01-03 Mar due to the return of old Region
2699.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at normal levels from 05-14 Feb and again from 26
Feb-03 Mar. Moderate levels are likely from 15-25 Feb due to
influence from recurrent CH HSSs.
Geomagnetic field activity is expected to be at quiet to unsettled
levels on 05 Feb, 15-17 Feb and 20-22 Feb, with isolated active
periods likley on 16 Feb. This activity is due to influence from
recurrent CH HSSs. Mostly quiet conditions are expected for the
remainder of the outlook period.
