From Accuweather.com:

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 flare is also expected to cause vibrant northern lights from the Arctic as far south as New York, the Dakotas, Washington and Michigan, with a smaller possibility of it going into Pennsylvania and Iowa, even Kansas.

The lights are currently estimated for 8 p.m. EDT Saturday arrival, with a possible deviation of up to seven hours. If the radiation hits much after dark settles on the East Coast the lights may be missed and will instead only be visible for the West.
