The National Oceanic and Atmospheric Administration posted this message to Facebook earlier today:

A G2 (Moderate) geomagnetic storm watch is in effect for the 23 March, 2019 UTC-day due to anticipated CME arrival. An asymmetric halo CME was observed in SOHO/LASCO coronagraph imagery and initial analysis of the CME in both LASCO and STEREO-A coronagraph imagery shows an Earth-directed component is likely. The CME was associated with a C4 flare on 20 March, 2019 at 1118 UTC (0718 EDT). Continue to monitor our SWPC webpage for additional updates."

Translation: We might be able to see the Northern Lights here in Southeast Minnesota. The solar storm will happen Saturday night and according to a CNN report: "UAF's Geophysical Institute says to look for the northern lights about three or four hours around midnight."
