One week ago, a spectacular northern lights display wowed millions of Americans. Experts and aurora chasers say that was likely just the beginning of the spectacles as our sun heads into what's known as the "solar maximum."

But when exactly will the northern lights appear again? Even though experts say conditions are primed for more aurora shows over the next few years, predicting exactly when and where they occur will continue to be a challenge. Even the best predictions can only accurately be made a few days or even hours in advance.

For those who caught the forecast in time last week and headed outside, the view was "epic," aurora chaser Melissa F. Kaelin told USA TODAY via e-mail days after the event. Last week's dramatic display of the northern lights near Dexter, Michigan, "rivals anything I've seen in 12 years of aurora chasing. The excitement still gives me chills," she said.
