Sun 'Hole' Expected to Produce Intense Auroras Tonight, Visible from 15 U.S. States
On June 25, a large coronal hole in the Sun's atmosphere is sending a high-speed stream of charged particles toward Earth, leading to the possibility of visible auroras across approximately 15 U.S. states.
The Space Weather Prediction Center forecasts a moderate G2 geomagnetic storm, which may make the northern lights visible, especially over Alaska and Canada, and could also be seen in the northern parts of the contiguous United States. This phenomenon occurs when solar wind interacts with Earth's magnetic field, causing the luminous displays known as auroras.
While typically best viewed after sunset or before sunrise, auroras can sometimes be seen from considerable distances, depending on geomagnetic activity. The event is linked to a coronal hole — an area of less dense plasma on the Sun — which facilitates the escape of charged particles into space.
The prediction maps indicate the areas where auroras are most likely visible, providing a rare opportunity for many in the U.S. to witness this natural light show.
