Space weather today in Bergen

Space weather in Bergen today

G1 minor geomagnetic storm forecast (NOAA, 2026-11-06 01:48 UTC). The planetary Kp index is 2.3 now and forecast to peak at Kp 5 in the next 24 hours. NOAA gives a 35% chance of R1–R2 radio blackouts today, 10% for R3 or stronger, and 5% for a solar radiation storm.

Radio: solar flares only black out HF radio on the half of Earth facing the Sun. The Sun is 38° below the horizon in Bergen now (2:53 am local time). The biggest flare in the past 24 hours was M3.5 at 7:33 pm local time, while Bergen was on the night side. HF radio fades here during geomagnetic storms and solar radiation storms (polar cap absorption at S1+).

GPS and power: GPS and satellite signals here are among the first affected: during G2+ storms the aurora overhead can add metres of error and brief loss of lock. Long power lines at this latitude see geomagnetically induced currents from G3 storms upward; operators get NOAA warnings.

Aurora chance tonight in Bergen

Aurora possible but cloudy: Kp 2.3 forecast, about 74% cloud overnight. At 61.0° N geomagnetic, Bergen needs about Kp 2 for aurora low on the northern horizon.

At the forecast Kp 5, the aurora's visible edge reaches Bergen.

NOAA 3-day space weather forecast

Chances that NOAA issues each level somewhere on Earth. Radio blackouts only affect the sunlit side; geomagnetic storms are global but strongest near the poles.

What the scales mean

Space weather is the Sun's effect on Earth. NOAA rates it on three 1–5 scales. R (radio blackouts) comes from solar flares: X-rays reach Earth in 8 minutes and disrupt HF radio on the sunlit side for minutes to hours. S (solar radiation storms) comes from energetic protons a few hours later, a hazard for satellites, polar flights and astronauts. G (geomagnetic storms) comes 1–3 days after a coronal mass ejection or a fast solar-wind stream hits the magnetic field: it drives the aurora and can upset GPS, HF radio and power grids.

The Kp index (0–9) measures geomagnetic activity in 3-hour blocks: Kp 5 is a G1 storm, Kp 6 G2, Kp 7 G3, Kp 8 G4 and Kp 9 G5. Flares are classed A, B, C, M and X by peak X-ray brightness, each class ten times the one before; M1 flares cause R1 blackouts and X1 flares R3.
