A storm on the sun may mean a colorful light show for people in the northern part of the country.
Scientists say that two solar storms are shooting out plasma towards the earth.
The plasma is interacting with the earth's magnetic field, and the result looks like northern lights, which are usually only seen in areas closer to the Arctic.
People were able to see the first light show Tuesday night, but there could be more Wednesday night from around Maine to Michigan.
Until now, scientists say the sun was having very few storms.
