Is that energy reaching and shaking our magnetic field?
G0 — No storm
The interplanetary magnetic field is pointing northward (Bz 0.0 nT), which shields us. Current planetary Kp is 1.3.

Aurora possible above ~63° latitude
NOAA's model peaks at 21% overhead-aurora probability. Cloud cover and city light still decide whether you actually see it.

Solar Wind Forecast
NOAA SWPC WSA-Enlil model — how current solar wind structures are propagating toward Earth.
WSA-Enlil models how solar-wind structures and coronal mass ejections propagate from the Sun toward Earth, giving forecasters roughly 1–4 days of advance notice. This image comes directly from NOAA's Space Weather Prediction Center and updates on NOAA's own schedule — it is a model forecast, not a live real-time feed, and may reflect NOAA's most recent model run rather than the current instant.

Earth's Magnetic Field
NOAA SWPC / USGS Boulder, Colorado ground magnetometer station.
Ground magnetometers measure changes in Earth's magnetic field at observatories on the ground. These measurements provide a direct view of how Earth's magnetic environment is responding locally. This chart shows the Boulder, Colorado station's own K-index — a single ground observatory, not a measurement of Earth's entire magnetic field.

Last refresh: Nov 5, 12:05 PM UTC. Providers are polled server-side roughly every ten minutes and cached; your browser never calls NOAA or NASA directly. Where a reading is missing, this page says so rather than substituting a value — a missing value is not a quiet condition. Known gaps: IMF By and electron flux are not collected by this pipeline. The IMF Bx, By and clock-angle panel above is a separate live read of NOAA's solar-wind magnetometer product, not stored history. CCOR-2 imagery is now shown above, sourced from a real endpoint inferred from NOAA's confirmed CCOR-1 sibling structure — not independently verified live from this deployment environment.
Space weather dashboard: common questions
How current is the data on this dashboard?
Readings come from NOAA and NASA public feeds. The Kp panel shows the observation time of the newest NOAA value in UTC. NOAA's official Kp is built from three-hour intervals, while solar wind and GOES X-ray flux are published far more often, with some NOAA plots updating every minute.
What do the G, S and R scales on the dashboard measure?
G rates geomagnetic storms from Kp (G1 is Kp 5, G5 is Kp 9). S rates solar radiation storms from the flux of energetic protons above 10 MeV. R rates radio blackouts from GOES X-ray flux, starting at an M1 flare for R1 and an X1 flare for R3. Each runs from 1 (minor) to 5 (extreme).
Why does a southward Bz matter for aurora?
When the interplanetary magnetic field points south (negative Bz), solar wind energy couples more efficiently into Earth's magnetic field, which is why forecasters watch it alongside solar wind speed. It does not guarantee a storm, because strength and duration matter too, but it is a key ingredient.
Why do flares, CMEs and storms show up at different times?
Flare light and X-rays reach Earth in about eight minutes, so radio effects are immediate. A coronal mass ejection travels as matter: the fastest Earth-directed ones arrive in roughly 15 to 18 hours and slower ones take several days. It causes a storm only if it is Earth-directed and its magnetic field connects with ours.
