Monitor sun activity and space weather. Real-time solar flares, geomagnetic storms, and aurora forecasts from NOAA SWPC.
☀️ Solar Flares
Live solar flare alerts from C-class to X-class events.
💨 Solar Wind
Real-time solar wind speed, density, and magnetic field direction.
🌌 Aurora Forecast
Predict northern and southern lights visibility with Kp index.
📡 Radio Blackouts
HF radio propagation impacts from solar radiation storms.
Solar Flare Classifications
- A/B-Class - Background levels, minimal impact
- C-Class - Small flares, minor radio effects
- M-Class - Medium flares, can cause brief radio blackouts
- X-Class - Major flares, significant radio/GPS disruption
Space Weather Impacts
Solar activity affects Earth in multiple ways:
- Geomagnetic Storms - Power grid fluctuations, satellite drag
- Radio Blackouts - HF communication disruption
- Aurora Activity - Northern/Southern lights visible at lower latitudes
- GPS Errors - Positioning accuracy degradation
- Aviation Radiation - Increased radiation on polar routes
Current Solar Cycle
We're in Solar Cycle 25, which began in December 2019. Peak activity expected 2024-2025 with increased flare and storm frequency.
Frequently Asked Questions
When can I see the aurora?
Aurora visibility depends on Kp index (geomagnetic activity). Kp 5+ brings aurora to mid-latitudes. Check our forecast for your location.
Do solar flares affect my electronics?
Everyday electronics are safe. Large flares can disrupt GPS, satellite communications, and in extreme cases, power grids.
How much warning before a solar storm hits Earth?
Solar flare radiation arrives in 8 minutes (light speed). CME particles take 1-3 days, giving advance warning time.
