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.
Latest NOAA aurora ovation map

Aurora Oval

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

Solar Wind Speed

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