Increased solar flare activity over the last few days will cause the northern horizon to light up for many states.

This phenomenon is most commonly seen in polar regions, but during geomagnetic storms, the auroras can extend further south. The recent storm forecasted by the National Oceanic and Atmospheric Administration (NOAA) suggests that the Northern Lights may be visible as far south as Washington to Maine.

A geomagnetic storm will expand visibility of the aurora borealis Thursday and Friday nights. See maps of which states will get to see the northern lights.

It’s best to capture the northern lights with a wide-angle lens, an aperture or F-stop of four or less and a focus set to the furthest possible setting, photography experts told National Geographic. If using a smartphone, NOAA said it’s best to enable night mode, disable flash and rely on a tripod to stabilize the image.
