Space weather today in Missouri City, TX

Space weather in Missouri City today

G1 minor geomagnetic storm forecast (NOAA, 2026-11-06 03:27 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 52° below the horizon in Missouri City now (9:33 pm local time). The biggest flare in the past 24 hours was M3.5 at 12:33 pm local time, while Missouri City was in daylight, so HF radio here may have faded briefly. HF radio is mainly hit by daytime solar flares (radio blackouts), not by geomagnetic storms.

GPS and power: GPS is normally unaffected; only severe G4–G5 storms cause noticeable errors here. Power grid effects are very unlikely at this latitude.

Aurora chance tonight in Missouri City

Unlikely tonight (Kp 2.3 forecast; Missouri City needs an extreme Kp 9 storm). At 38.0° N geomagnetic, Missouri City is far from the auroral oval; only extreme Kp 9 (G5) storms such as May 2024 bring the aurora into view, mostly to cameras.

At the forecast Kp 5, the aurora's visible edge stays about 1,690 km north of Missouri City.

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.
