Solar Flare Monitor & Space Weather Tracker
Use this free space weather monitor to follow solar activity in real time: X-ray flare class, planetary Kp index, solar wind plasma, sunspot regions, SWPC scales, and aurora forecast guidance. It is built for anyone watching geomagnetic storms — from aurora chasers to radio operators and aviation weather hobbyists.
Start with current scales and alerts, then drill into Kp history, solar wind speed, and flare timelines. Pair storm watches with the Stargazer sky forecast when aurora potential rises, or read the weekly context on the weather blog.

Space Weather FAQ
- What is a space weather monitor?
- A space weather monitor tracks solar and geomagnetic conditions in near real time — solar flares (X-ray flux), the planetary Kp index, solar wind speed and density, sunspots, and aurora outlooks — so you can see storm risk as it develops.
- What does the Kp index measure?
- The Kp index is a 0–9 scale of global geomagnetic activity. Higher Kp means a stronger geomagnetic storm and a better chance of aurora at lower latitudes. Live Kp and recent history are shown on this page from NOAA SWPC data.
- How do I track solar flares and solar storms?
- Watch GOES X-ray flux for flare class (C, M, X), check SWPC scales for radio blackout and radiation storm levels, and follow solar wind and Kp for geomagnetic response. This solar flare monitor and storm tracker combines those feeds in one terminal.
- Where does 16 Bit Weather get space weather data?
- Primary sources are NOAA Space Weather Prediction Center (scales, Kp, solar wind, alerts), NASA SDO imagery, and ESA/NASA SOHO coronagraph frames. Data refreshes automatically while you keep the page open.
