3-day Kp forecast

Kp is issued in 3-hour blocks. A higher Kp pushes the aurora toward the equator: the table shows how far it can be seen.

Day (UTC)	Max Kp	Level	Aurora seen down to (geomagnetic)
2026-11-06	4.7	active	54°
2026-11-07	5	G1 minor storm	53°
2026-11-08	5	G1 minor storm	53°

Solar flares this week

40 flares in the past 7 days, 1 of them M-class or stronger. M1 and stronger flares cause radio blackouts on the sunlit side of Earth. Times in UTC.

M3.5 flare peak 2026-11-05 18:33 UTC, R1 minor radio blackout
C2.9 flare peak 2026-11-05 21:34 UTC
C2.5 flare peak 2026-11-06 00:24 UTC
C2.2 flare peak 2026-11-04 17:34 UTC
C1.3 flare peak 2026-11-05 22:31 UTC
C1.2 flare peak 2026-11-05 22:21 UTC

Space weather in your city

Geomagnetic latitude decides how much a storm matters where you are: how strong a storm brings the aurora into view, and how exposed GPS, HF radio and power lines are.

New York City	49.9° N	7
London	53.3° N	5
Tokyo	27.8° N	9+
Los Angeles	40.2° N	9+
Toronto	52.8° N	6
Sydney	40.2° S	9+
Berlin	52.2° N	6
Chicago	50.7° N	7
Mumbai	11.4° N	9+

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.
