Space Weather Dashboard

Space weather describes the conditions in space driven by the Sun's activity. Solar flares, coronal mass ejections (CMEs), and high-speed solar wind streams can all interact with Earth's magnetic field, creating geomagnetic storms that produce stunning aurora displays but can also disrupt satellite operations, GPS navigation, radio communications, and even power grids.

The Kp indexis the primary measure of geomagnetic activity, ranging from 0 (quiet) to 9 (extreme storm). It's derived from ground-based magnetometer stations worldwide and updated every 3 hours. When the Kp index rises above 5, NOAA issues geomagnetic storm warnings on the G1–G5 scale.

Solar flaresare classified by their X-ray intensity: C-class (small), M-class (medium), and X-class (major). Each class is 10 times more powerful than the previous. The strongest flares can cause radio blackouts lasting hours and launch CMEs that reach Earth in 1–3 days.

Understanding space weather is increasingly important as our civilization relies more on technology vulnerable to solar activity — from the satellites that power GPS and weather forecasting to the astronauts aboard the International Space Station and future lunar missions.
