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 8.
The geomagnetic field is expected to see active conditions September 17-18 and disturbed September 19. Solar activity is expected to be at quiet conditions September 17-19, 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 4 near 12:00 UT, September 16, 2021.
The Wolf Sunspot number today was 0. Solar radio Flux 10.7 was 75 on September 16, 2021.
