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.

Quick Read

Low Missouri potential right now

Storm Threshold

Kp 5+

Best Setup

Dark sky + clear weather

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.

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.

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.
