A solar flare that occurred around 2 a.m. Thursday morning may create a spectacular display of northern lights Saturday evening. The midlevel flare had a long duration and was directed at Earth. According to AccuWeather.com Astronomer Hunter Outten, who stated that this flare was “impressive”, these are the best conditions for seeing a direct effect on our planet.
On the Kp index, the flare has been categorized at 6 to 8. This is a scale for measuring the intensity of a a geomagnetic storm. The 6 to 8 rating means that the effects of the radiation will have a greater reach. The radiation from such a flare may cause radio wave disturbances to electronics such as cell phones, GPS and radios, causing services to occasionally cut in and out. While traveling slower than was originally anticipated, the flare effects are moving towards Earth at 1000 km per second.
Viewing conditions will be best in the mid-Atlantic, specifically for parts of Pennsylvania and the Delmarva.
