☀ Helios Solar Watch · 2026-07-26 16:00 UTC
QUIET

Geomagnetic conditions remain quiet, though solar flare activity has increased due to an M-class eruption from AR4494. The solar environment is currently stable but bears monitoring for further flaring potential.

Next 24 h

Expect geomagnetic conditions to remain largely quiet through the next 24 hours, with the Kp-index likely rising to 3.0 by the next cycle.

more

Further C-class flares are highly probable, with a 50% chance of additional M-class activity as AR4494 transits the solar disk.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes (40-60°N) at current activity levels.

more

Observers at very high latitudes may see minor activity, but no significant displays are forecast for the next 24 hours.

👁 Watch for

Monitor active region AR4494 for any signs of magnetic complexity development that could trigger a stronger, more eruptive solar flare.
