Highlights of Solar and Geomagnetic Activity
11 - 17 July 2022
Solar activity reached high levels this period due to low level,
impulsive M-class flare activity. On 11 Jul Region 3056 produced an
M1.3 flare at 2343 UTC. On 14 July Region 3058 was responsible for
an M1.2 flare at 0431 UTC and an M2.8 flare at 2148 UTC. A CME was
associated with the M1.2 from 3058, but was not directed at Earth.
Finally, on 16 July Regions 3057 and 3055 produced a M1.1 at 0629
UTC and a M1.4 at 1539 UTC respectively. A relatively narrow CME was
observed emerging from the SW limb shortly after the aforementioned
M1.4 flare from Region 3055, but modeling determined this event to
be off the Sun-Earth line. Numerous C-class activity was noted from
multiple regions over the course of the period.
Additional activity included the eruption of an approximately 37
degree long filament oriented in an east to west fashion and
centered near N31W05 just after 1308 UTC on 15 July. The resultant
slow moving, partial halo CME was modeled and determined to have an
Earth-directed component with a likely arrival of 20 July.
The greater than 10 MeV proton flux at geosynchronous orbit began
the period in a slightly enhanced state with a peak of flux of 1.68
pfu occurring at 11/0305 UTC. This slight enhancement was due to
C-class flare activity from the western limb that had occurred
during the previous period. The 10 MeV proton flux continued a
downward trend to background levels over the course of 11 July and
remained there for the duration of the period.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels in response to positive polarity CH HSS effects at
approximately 16/1025 UTC with a peak flux of 5,270 pfu observed at
17/1830 UTC.
Geomagnetic field activity ranged from quiet to active with an
isolated G1 (Minor) storming period. Quiet to active levels were
observed 11 July with the likely arrival of transient- like
influence. G1 (Minor) geomagnetic storming was observed on 12 July
at approximately 1332 UTC due to likely transient influence paired
with the onset of a positive polarity CH HSS. Mostly quiet levels
returned 13 July, with a few isolated unsettled periods occurring
15-16 July.
Forecast of Solar and Geomagnetic Activity
18 July - 13 August 2022
Solar activity is expected to be at low levels 18-23 July and 31
Jul-13 Aug , with a chance for R1-R2 (Minor-Moderate) radio
blackouts from active, complex regions. Mostly very low to low solar
activity is anticipated for 24-30 July due to recurrence.
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 18-20 Jul, 24-30 Jul, and 12-13 Aug
due to recurrent CH HSS.
Geomagnetic field activity is expected to be quiet to unsettled
18-19 Jul under waning CH HSS effects. Primarily unsettled to active
levels are expected 20-25 July, with G1 (Minor) storming being
likely on 21 July, due to the arrival of the slow CME produced by a
large filament eruption that occurred on 15 July and recurrent CH
HSS effects. Unsettled conditions are expected 03-04 Aug and 10-12
Aug due to recurrent CH HSS effects. Primarily quiet levels are
expected 26 July through 02 Aug, 05-09 Aug and 13 Aug barring new
solar activity.
