If you forgot to buy the chocolates and flowers for your Valentine this year, look up later tonight. The National Oceanic and Atmospheric Administration predicts that the aurora borealis, better known as the Northern Lights, will be visible in parts of Canada and the northern United States, including Wisconsin. The agency says a geomagnetic storm is causing a fast-moving solar wind stream to Earth, prompting the technicolor light show. While the predicted snowstorm may hamper your efforts, NOAA recommends getting away from the city and trying to catch your view of the Northern Lights between 10 p.m. and 2 a.m. The frequency of the Northern Lights viewings and the intensity of the colors on display are all thanks to the sun and where it is in its 11-year solar cycle. Last May, Americans all over the United States were able to catch the aurora borealis thanks to the strongest solar storm in over 20 years.
