EXTERNAL FIELDS/EFFECTS
The geomagnetic field saw quiet conditions today. The AP level was 4. High latitude geomagnetic field also saw quiet conditions with AP 3.
The geomagnetic field is expected to see quiet October 25-26 with disturbed periods October 27. Solar activity is expected to be at quiet conditions October 25-27, 2021 with a slight chance (10%) of an M-class flare. SWPC expects a proton storm with 1% likelihood.
The maximum disturbance in the geomagnetic field today occurred with KP 2 near 12:00 UT, October 24, 2021.
The Wolf Sunspot number today was 32. Solar radio Flux 10.7 was 87 on October 24, 2021.
