Highlights of Solar and Geomagnetic Activity 18 - 24 July 2022
Solar activity was low. Only C-class flare activity was observed during the period with a C5.6 flare from Region 3060 and a C6.1 from Region 3056 on 21 Jul being the largest events. The C5.6 flare caused the eruption of an approximately 12 degree long filament centered near N15W01. This resulted in Type II and IV radio sweeps, est. 1063 Km/s, and a full halo CME. No other 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 high levels on 20-21 Jul with a peak flux of 1,920 pfu observed at GOES at 20/1620 UTC. The 2 MeV electron flux was at the background to moderate levels 18-19 Jul and 22-24 Jul.
Geomagnetic field activity reached active to G1 (Minor) storming levels on 19 Jul with the arrival of the 15 Jul CME from the previous reporting period. G1 (Minor) levels were reached again on 21 Jul due to negative polarity CH HSS effects. Predominantly unsettled levels continued afterward until early on 23 Jul when an isolated G1 (Minor) storming period was observed yet again with the arrival of the full halo CME on 21 Jul. Primarily quiet conditions were observed on 18, 20 and 23-24 Jul with isolated unsettled periods.
Forecast of Solar and Geomagnetic Activity 25 July - 20 August 2022
Solar activity is expected to be at low levels with a slight chance for R1-2 (Minor-Moderate) radio blackouts through 08 Aug. Activity is expected to increase to a chance for R1-2 (Minor-Moderate) radio blackouts 09-18 Aug with the anticipated return of more active, complex regions. Low levels will likely return 19-20 Aug barring significant development of new active regions.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels through 27 Jul in response to negative polarity CH HSS effects. Background to moderate levels are anticipated for 28 Jul through 11 Aug. A chance for high levels returns 12 Aug through the remainder of the period due to recurrent CH features.
Geomagnetic field activity is expected to reach G1 (Minor) storming on 17 Aug, and reach active levels on 31 Jul, 03 Aug and 18-19 Aug due to recurrent CH HSS features. Otherwise, quiet to unsettled conditions are expected for the forecast period.
