Solar activity remains in an unsettled state characterized by frequent M-class flaring despite low current geomagnetic indices. Seven active regions are currently identified on the solar disk, with AR4513 showing notable complexity.
⚠ Electron flux F3 reached · 4 more below
Geomagnetic activity is expected to remain largely quiet, with a brief uptick to Kp 3.67 anticipated late on August 21st. Flare probability remains elevated for the next 24 hours, with a 55% chance of further M-class activity.
Aurora visibility is not expected for mid-latitudes at this time.

Observers at very high latitudes may see minor activity if the forecast Kp 3 peak materializes, but no significant displays are anticipated.
Monitor the evolution of active region AR4513 as it rotates across the solar disk, as its current classification suggests potential for further eruptive activity.
