Solar activity remains stable with moderate flux and quiet geomagnetic conditions.
SOLAR: MODERATE
GEO: QUIET

Active Regions
4
X-Ray
A/B (quiet)

The Sun remains in a stable state with low-level activity, presenting no significant space weather hazards to Earth. Geomagnetic conditions are currently quiet and are expected to remain within nominal ranges over the next 24 hours.

F10.7 Solar Flux
140.0
sfu · >150 = high activity

Current solar activity is characterized by a stable F10.7 flux of 140 sfu, indicating moderate levels of solar output. Flare activity is limited to minor C-class events, with no significant X-ray bursts or coronal mass ejections detected. The planetary K-index is currently at 1.0, reflecting a very calm geomagnetic environment.

Key Metric

The Kp index of 1.0 confirms a stable magnetosphere, ensuring optimal conditions for satellite operations and radio communications.

We expect the geomagnetic field to remain largely quiet, with a slight, non-impacting rise in the K-index to approximately 3.67 as we move into the next 24 hours. No significant space weather events or disturbances are anticipated for orbital or terrestrial systems.

🌌 Aurora Outlook

Aurora visibility is restricted to high-latitude regions and will remain largely elusive for mid-latitude observers. Current conditions do not support auroral displays at latitudes below 60 degrees.
