The northern lights could return to New York in June 2024. What you need to know

Rochester could get another chance to see the northern lights in early June, when the enormous sunspot responsible for May’s spectacular aurora once again faces land.

The aurora, the light seen in the night sky due to electrons from space colliding with Earth’s upper atmosphere, is caused by interactions between the solar wind from the sun and the planet’s magnetic field. Geomagnetic storms, like those in May, can make the aurora brighter and appear farther from the poles.

According to NASA, the sun rotates on its axis approximately once every 27 days. This rotation means that features on our star’s surface, including sunspots, are not always facing Earth. The optimal dates for the Earth to be in line with these displays is June 4-6.
