Solar activity is currently marked by moderate M-class flare production from AR4513, though global geomagnetic conditions remain quiet. We anticipate a minor increase in geomagnetic disturbance heading into the early hours of August 27.
⚠ Electron flux F3 reached · 4 more below
Geomagnetic activity is expected to rise to Kp 3.67 by 00:00 UTC on August 27. Flare probabilities remain skewed toward C-class events, with a continued 30% chance of further M-class activity originating from AR4513 over the next 24 hours.
Aurora visibility is not expected at mid-latitudes at this time.

Observers in high-latitude regions may see minor activity as the Kp-index climbs late tonight, but displays will likely be faint and confined to northern polar regions.
Monitor AR4513 closely for further M-class flare production, as its current magnetic complexity remains the primary driver of solar activity.
