Solar Wind Stream
Solar Wind & IMF
Monitor live solar wind speed, density, and interplanetary magnetic field conditions before their effects show up in geomagnetic indices. This solar wind and IMF page focuses on plasma flow, southward Bz, and propagated near-Earth context that often sets the stage for geomagnetic storms and stronger aurora conditions.
Solar wind plasma is temporarily unavailable (SWPC request failed (404)).
IMF data is temporarily unavailable (SWPC request failed (404)).
Current Conditions
Snapshot values derived from NOAA SWPC live solar wind plasma and IMF feeds.
Solar wind telemetry is temporarily unavailable.
IMF Orientation
The interplanetary magnetic field is the most important upstream control on whether solar wind can couple efficiently into Earth's magnetosphere.
IMF data is temporarily unavailable.
Solar Wind Plasma
Speed, density, and temperature show how energetic the upstream solar wind flow is before it interacts with Earth.
Solar wind plasma data is temporarily unavailable.
Propagated Geospace Context
NOAA's propagated product helps bridge upstream measurements toward near-Earth conditions as the solar wind approaches geospace.
Propagated solar wind guidance is temporarily unavailable.
About This Data
NOAA SWPC live solar wind and magnetic-field products are sampled upstream of Earth, then propagated forward to provide a simple geospace context layer. This page is designed for solar wind monitoring and geomagnetic storm awareness rather than as a formal forecast product.
