What it does
Track coronal mass ejections from the Sun to Earth in real time. CME Tracker visualizes every CME NASA catalogs, estimates arrival times, and shows geomagnetic storm impact — plus replays of famous solar storms.
Follow every coronal mass ejection from the Sun to Earth on a live map — physics-based arrival estimates, historical replays, a 3D view, and free aurora alerts.
Every coronal mass ejection NASA catalogs, drawn from the Sun to Earth with its measured speed and aim, updated every few minutes. Ten spacecraft feeds in one picture you can read at a glance: the most comprehensive and understandable view of space weather anywhere. Fresh NASA & NOAA data every few minutes. Each CME is drawn with its measured direction, width, and speed — so you can see at a glance whether it's aimed at Earth or sailing past. The map is a time machine: run the clock forward to preview arrivals, or rewind and replay history — the 2024 Gannon superstorm, the 1859 Carrington Event, and more, with the real data behind them. A free six-module course that runs on this map: click…from cmetracker.ai

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
