Space Weather Observatory
Track space weather in near real time with a live dashboard for solar flares, coronal mass ejections, geomagnetic storms, radio blackouts, and operational alerts. This observatory brings together NASA DONKI events and NOAA SWPC monitoring so you can follow what the Sun is doing and how Earth responds.
Space weather refers to the changing conditions in the space environment between the Sun and Earth. The Sun constantly emits a stream of charged particles called the solar wind, and occasionally releases bursts of energy and matter that can interact with Earth's magnetic field and upper atmosphere.
Why it matters
Space weather can disrupt GPS signals, degrade high-frequency radio communications, damage satellites, endanger astronauts, and in extreme cases cause widespread power grid failures. It also produces the aurora borealis and australis.

About this data
Event data comes from NASA's DONKI (Database Of Notifications, Knowledge, Information) maintained by the CCMC. Operational alerts are supplemented by NOAA SWPC. Data refreshes automatically while this page is open.
