NOAA’s Aurora Forecasts

NOAA aurora forecast map

It turns out that auroras are a thing you can generate weather maps for. NOAA’s Space Weather Prediction Center has this experimental Aurora Dashboard that predicts the visibility of the aurora borealis and australis for the next two nights.

(And space weather is in fact something that NOAA tracks: the term covers the effects of solar phenomena, cosmic rays, the ionosphere—think aurora sunspots, solar flares, coronal mass ejections, and their impacts on climate, communications, the power grid, GPS.)
