EXTERNAL FIELDS/EFFECTS
The geomagnetic field saw stormy conditions today. The AP level was 41. High latitude geomagnetic field also saw strong storm conditions with AP 47. Strong, sudden commencement storms such as this can enhance seismicity especially near the geomagnetic equator or near the polar auroral regions. This is the strongest global geomagnetic storm since AP reached 45 on September 1, 2019 more than 1.5 years ago.
The geomagnetic field is expected to see unsettled conditions May 14 with minor storm periods May 13 and quiet May 15. Solar activity is expected to be at quiet conditions May 13-15, 2021 with a slight chance (5%) of an M-class flare. SWPC expects a proton storm with 1% likelihood.
The maximum disturbance in the geomagnetic field today occurred with KP 7 near 14:00, May 12, 2021.
The Wolf Sunspot number today was 31. Solar radio Flux 10.7 was 75 on May 12, 2021.
