X-Ray
A/B (quiet)

The sun remains in a state of stable, low-intensity activity with no significant geomagnetic disturbances expected. F10.7 flux levels remain moderate, reflecting a typical state for the current cycle phase.

F10.7 Solar Flux

sfu · >150 = high activity

Current solar conditions are quiet, with the planetary K-index holding at 1.0. While there are four active regions on the disk, X-ray flux remains at background levels (B-class), indicating minimal flare activity. The F10.7 solar radio flux of 131 sfu confirms moderate background output, posing no immediate concerns for satellite operations or power grid stability.

Key Metric

The F10.7 solar radio flux of 131 sfu is the primary metric to monitor, as it characterizes the overall level of solar atmospheric heating and ultraviolet radiation.

Geomagnetic conditions are expected to stay quiet over the next 24 hours, with the Kp index likely to fluctuate between 0 and 2. No significant solar radiation or radio blackouts are anticipated as solar flare activity remains within nominal ranges.

🌌 Aurora Outlook

Aurora visibility is not expected for mid-latitudes. The current geomagnetic environment is too quiet to drive auroral activity outside of the immediate polar regions.
