Key Facts
The NOAA forecast a Kp index of four on a scale of nine for Saturday night.
A Kp in the range of three to five means the aurora will become brighter and there will be more auroral activity as it moves further from the poles.
Minor to moderate radio blackouts are likely, with a slight chance of a “strong” or greater blackout between Saturday and Sunday.
Sunday’s forecast is more muted, with visibility expected only in northern Minnesota and a Kp of two.
