Highlights of Solar and Geomagnetic Activity 23 - 29 July 2018
Solar activity was very low throughout the week. No active regions with sunspots were observed this period and a single B1 flare at 29/2148 UTC, from an unnumbered region behind the eastern limb, was the only flare reported this week.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 25-29 Jul and moderate levels were observed on 23-24 Jul.
Geomagnetic field activity reached active levels on 24 Jul due to the influence of a negative polarity coronal hole high speed stream. Quiet to unsettled conditions were observed on 25 Jul and generally
quiet conditions were observed throughout the remainder of the period.
Forecast of Solar and Geomagnetic Activity 30 July - 25 August 2018
Solar activity is expected to be very 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 reach high levels on 30-31 Jul, and 21-25 Aug. The greater than 2 MeV electron flux is expected to remain below event
threshold throughout the remainder of the outlook period.
Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic storm levels on 20 Aug and active levels are likely on 17 and 21 Aug, all due to the influences of multiple coronal hole high speed streams. Quiet or quiet to unsettled levels are expected throughout the remainder of the outlook period.
