Geomagnetic Activity

Quiet
Recent Kp readings from NOAA SWPC. Values of 5 or higher indicate geomagnetic storm conditions.

Aurora Outlook for Missouri

Quiet to mildly unsettled geomagnetic conditions. Aurora is not likely this far south right now.

Aurora Viewline Tonight & Tomorrow Night

NOAA Experimental Forecast

These NOAA SWPC viewline graphics show the southern line where the aurora may be visible on the northern horizon for tonight and tomorrow night across North America.

NOAA Tonight's Aurora Viewline Forecast
Tonight's Aurora Viewline
Forecast southern extent for where aurora might be seen on the northern horizon tonight, based on NOAA's forecast Kp window.
NOAA Tomorrow Night's Aurora Viewline Forecast
Tomorrow Night's Aurora Viewline
Next-night forecast viewline from the same NOAA product, useful for seeing whether the southern visibility edge shifts north or south.

How to Read It

Red Line
Southern viewing edge
Green to Red Oval
Brighter aurora zone
Missouri Right Now
Unlikely

If Missouri is north of or close to the red viewline, there is at least a chance of seeing aurora low on the northern horizon. If the line stays well north of Missouri, viewing here is much less likely.

Actual visibility still depends on darkness, cloud cover, and local light pollution.

GOES X-ray Flux

B-Class
The long-wave GOES X-ray channel is what drives the common A/B/C/M/X flare classes.

Aurora Oval

Latest NOAA ovation imagery. Even when the oval expands, local cloud cover still matters for Missouri viewing.

Solar Wind Speed

373 km/s
Faster solar wind can help drive stronger geomagnetic activity when other conditions line up.
