EXTERNAL FIELDS/EFFECTS
The geomagnetic field saw stormy conditions today. The AP level was 26. High latitudes also saw active conditions with AP 20. The current strong geomagnetic storm is likely for several more days bringing fresh seismic enhancement in the several days after it ceases. A major solar flare with this activity could trigger a major earthquake at this time. A series of three M-class solar flares occurred today possibly leading to enhanced geomagnetic activity in the next several days and induced seismicity at that time. These are the largest M-class flares recorded by SWPC since July 16, a month ago.
The geomagnetic field is expected to see major storms August 19 with minor storm periods August 20 and disturbed August 21. Solar activity is expected to be at quiet levels August 19-21 with a slight chance (40%) of an M-class flare and 10% chance of an X-class flare. SWPC expects a proton storm with 10% likelihood likely towards the end of this period.
The maximum disturbance in the geomagnetic field today occurred with KP 6 at 18:00 UT, August 18, 2022.
The Wolf Sunspot number today was 83. Solar radio Flux 10.7 was 123 on August 18, 2022.
