At Kp 7, Moorhead needs a severe geomagnetic storm before anything shows above the northern horizon. Storms that size arrive a handful of times per solar cycle and announce themselves a day or two ahead. Watching for one beats picking dates and hoping.

The months that actually deliver
Counting only nights that were both stormy enough and dark enough, May, September and August came out ahead in Moorhead. That is storm season and darkness overlapping — the equinoxes tend to be geomagnetically active, and the nights are already long by then.
Darkest nights of the coming year
A bright moon washes out a weak display as effectively as street lighting. These new moons fall inside the Moorhead viewing season.

Where the horizon opens up near Moorhead
The display sits low on the northern horizon, so what beats a better forecast is open ground facing that way. Height gets you above the town glow; water gives you an unbroken skyline. These are within a short drive of Moorhead.

What to do with the daylight
Aurora watching is a night job, and in winter that leaves a short, bright day to fill. Close to Moorhead you will find KVNJ-TV (Fargo), KDSU-FM (Fargo) and WDAY-AM (Fargo), and for a day when the cloud sits low, Clay County, Plains Art Museum and Fargo Air Museum are indoors and near by.
Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.
