Space weather models predict the storm will peak Saturday evening and night with the potential for the lights to be high above the horizon as far south as Seattle, Chicago and Boston, and visible on the horizon as far south as Oregon, St. LEARN FROM FOX WEATHER: 7 Things To Know About The Northern Lights When they do that, they release a little bit of light." "And then (the molecules) relax back down to ground state. "It's basically just an electrical current."Īs the electrons hit the oxygen and nitrogen molecules, it "dumps in a little energy," Hampton says. "The production of the colors is very similar to what you see in a neon sign," Don Hampton, a researcher at the University of Alaska, Fairbanks, told FOX Weather. The flares bring a barrage of electrons that interact with oxygen and nitrogen in Earth's magnetic field that surrounds the outside of our planet. Still, the most notable effect is the Northern Lights, which usually follow a few days after solar flares erupt. It pays to stay tuned in.Geomagnetic weather can disrupt GPS satellites and radio depending on the severity of the solar storm. When this energy sweeps by the earth 1-to-3 nights later there is a very good chance of aurora activity. In the explosive event that a coronal mass ejection (CME) is reported it's time to hop into action because this super-charged solar wind is traveling fast (maybe 3-to-5 million miles per hour). Listed below are some websites of organizations that monitor the sun, measure the solar wind in real-time (now), and make aurora predictions. I've seen the northern lights as early as 8pm and as late as 8am. The peak hours are between 11pm and 2am, however, anytime it’s dark there is hope. Mythbuster: Contrary to popular belief, it does not have to be cold to see the aurora, just dark and clear.and clear skies usually mean it’s cold, hence the association between auroras and chilly nights. The winter months of October-thru-February are also good (there is definitely no shortage of darkness!). Statistically, the equinox months of September and March are best for aurora activity. Auroras can still be spotted south of about 50° latitude during the summer. During the summer months of May, June and July it is just too bright to see them in the far northland. These are the nights with darkness in them. Best Months?Īurora Borealis season in northern polar latitudes (Alaska, northern Canada, Greenland, Iceland, Norway, Sweden, Finland and Siberia) runs from August-thru-April.
The big question now is what will the upswing into Solar Cycle 25 present? Should get better & better as we head toward the predicted peak in 2025. Despite all the negative press the trough gets, I enjoyed the low phase and attained my goal of one “hero shot” per year ( 2017, 2018, 2019, 2020). The more sunspots, the more solar flare energy is being released into space (which means more aurora activity!).įor 400 years, from the time of Galileo until now, we have been keeping track of the number of these sunspots and, as the trends show in these two graphs, this cycle is predictable.Ī: We are just starting to come out of a 4-year trough of Solar Cycle 24. This is known as the solar cycle and is measured by the number of sunspots visible on the sun. Every eleven years or so it beats, and it beats hard. If that same sunspot (or coronal hole) is still active it will have rotated around with the sun and will be, once again, in geoeffective position (pointing toward earth).and hosing us with an enhanced flow of aurora-generating solar wind. Therefore, sunspots, like those seen on this solar image to the left, are like a giant revolving firehose emitting energy into space for sometimes months at a time.Īfter an active aurora night, mark that date on a calendar and in 27-28 days pay close attention to the sky. On average, the sun revolves on its axis once every 27-28 days as seen from earth. This is a very helpful tool for predicting auroras. Northern Lights Forecast 27-Day Aurora Forecast
