Solar storm forecast Yakutsk
Space weather today in Yakutsk
Updated
G1 minor geomagnetic storm forecast. Aurora in Yakutsk: possible tonight: Kp 4.7 forecast (needs about Kp 5); check the clouds and look north It is daytime in Yakutsk, so a strong solar flare right now would affect HF radio here.
Space weather in Yakutsk today
G1 minor geomagnetic storm forecast (NOAA, 2026-11-06 03:18 UTC). The planetary Kp index is 2 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 12° above the horizon in Yakutsk now (12:25 pm local time). The biggest flare in the past 24 hours was M3.5 at 3:33 am local time, while Yakutsk was on the night side. HF radio can fade at night during strong storms.
GPS and power: GPS is normally unaffected; strong G3+ storms can degrade precision positioning (surveying, farming RTK) for hours. Grid effects need G4–G5 storms here; the last big one was May 2024.

Aurora chance tonight in Yakutsk
Possible tonight: Kp 4.7 forecast (needs about Kp 5); check the clouds and look north. At 53.4° N geomagnetic, Yakutsk needs about Kp 5 for aurora low on the northern horizon.
At the forecast Kp 5, the aurora's visible edge reaches Yakutsk.
| Day (UTC) | Max Kp | Level | Aurora possible at Yakutsk? |
|---|---|---|---|
| 2026-11-06 | 4.7 | active | Yes |
| 2026-11-07 | 5 | G1 minor storm | Yes |
| 2026-11-08 | 5 | G1 minor storm | Yes |
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.

|---|---|---|---|---|
| 2026-11-06 | 35% | 10% | 5% | G1 minor |
| 2026-11-07 | 35% | 10% | 5% | G1 minor |
| 2026-11-08 | 35% | 10% | 5% | G1 minor |

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.
