Highlights of Solar and Geomagnetic Activity 20 - 26 June 2022
Solar activity was at low levels through the period with C-class flare activity observed from 6 separate regions. The majority of the flare activity was observed from Region 3038 (N16, L=053, class/area Ehi/580 on 24 Jun) with 22 C-class flares observed during the period, the largest a C5.7 event at 20/0618 UTC. Region 3840 (S13, L=325, class/area Cso/160 on 24 Jun) contributed 8 C-class flares, the largest a C2.9/Sf at 22/0506 UTC. During the period, a pair of DSFs were observed that both had possible Earth-directed components. The first was an 18 degree filament, centered near N25W28, that lifted off at about 24/0756 UTC, viewed in GOES-16 SUVI 304 imagery. The second was a 35 degree filament, centered near S53E09, that lifted off at about 26/0128 UTC, viewed in GOES-16 SUVI 304 imagery.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 24 Jun and high levels on 20-23 Jun and 25-26 Jun with a peak flux of 2,040 pfu observed at 25/1520 UTC.
Geomagnetic field activity ranged from quiet to minor storm levels. Quiet to unsettled levels were observed on 20-24 Jun due to positive polarity CH HSS influence (20-21 Jun) and negative polarity CH HSS influence (22-24 Jun). Active to G1 (Minor) storm levels were observed on 25-26 Jun due to negative polarity CH HSS influence. During the period, solar wind speeds ranged from a low of near 400 km/s on 23 Jun to a high of about 700 km/s on 26 Jun. Total field remained below 15 nT while the Bz component varied between +/- 12 nT. Phi angle was in a positive orientation on 20-21 Jun and rotated to a negative orientation on 22-26 Jun.
Forecast of Solar and Geomagnetic Activity 27 June - 23 July 2022
Solar activity is expected to be at very low to low levels through the outlook period.
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 on 27 Jun - 04 Jul and 15-23 Jul due to CH HSS influence. Low to moderate levels are expected on 05-14 Jul.
Geomagnetic field activity is expected to be at unsettled levels on 27-29 Jun, 08-11, 14-16 and 22-23 Jul with active intervals likely on 27 and 29 Jun and 23 Jul due to recurrent CH HSS activity coupled with CME activity on 27 and 29 Jun from the 24 Jun and 26 Jun CMEs, respectively.
