Active Regions
7
X-Ray
A/B (quiet)

Solar activity is currently characterized by significant flaring from AR4419 and AR4423, despite a quiet geomagnetic environment. While Earth’s magnetic field remains undisturbed, the high frequency of solar flares necessitates vigilance for potential impulsive radio disruptions.

The sun is currently hosting seven active regions, with AR4419 exhibiting complex magnetic structures capable of X-class events. The F10.7 index is at 113.0 sfu, indicating moderate solar activity. Geomagnetic conditions are stable with a Kp-index of 1.3, showing no current influence from the recent flare activity.

Key Metric

The M-class flare frequency is the most critical metric, as it suggests underlying magnetic instability in active regions that could impact shortwave radio propagation.

Geomagnetic activity is expected to remain quiet to unsettled, reaching a Kp of 3.0 by early April 25. Flare potential remains elevated, with a 30% probability of further M-class events as the active regions continue to evolve.

🌌 Aurora Outlook

Aurora visibility is not expected at mid-latitudes over the next 24 hours. Observations should be confined to high-latitude regions, where only minor, isolated auroral displays are possible.
