Solar activity remains stable and quiet with low geomagnetic disturbance
SOLAR: MODERATE

Active Regions
3
X-Ray
A/B (quiet)

Solar activity is currently stable, with geomagnetic conditions remaining at quiet levels. The sun is exhibiting moderate activity with six active regions present, but none currently pose an immediate threat of significant terrestrial impact.

Planetary Kp-Index

F10.7 Solar Flux
135.0
sfu · >150 = high activity

The planetary K-index is holding steady at Kp 2.0, indicating a lack of geomagnetic storming. The F10.7 solar flux is at 135 sfu, reflecting a moderate level of solar output typical for the current cycle. X-ray flux remains in the A/B range, with only minor C-class flare activity observed over the last 12 hours.

Key Metric

The F10.7 solar flux of 135 sfu is the primary indicator of ongoing solar cycle activity, confirming that despite the quiet geomagnetic state, the sun remains moderately active.

Geomagnetic conditions are expected to remain at quiet levels, with Kp values not projected to exceed 2.33 in the next 24 hours. Radio propagation conditions should remain stable, though minor, localized fluctuations are possible given the 90% probability of low-level C-class flares.

🌌 Aurora Outlook

Aurora activity is expected to be confined to high latitudes. Observers at mid-latitudes (40-60°N) should not expect visible displays under current conditions.
