WASHINGTON (Sinclair Broadcast Group) -- The National Oceanic and Atmospheric Administration issued a geomagnetic storm watch in effect for Wednesday and Thursday due to an impending solar storm.

The storm watch is on its lowest level, G1. Levels can potentially peak all the way up to G5, according to Science Alert. NOAA tells ABC News this will be a minor storm.

A solar storm happens when flares from the sun erupt in the sun's atmosphere. When they take place on the part of the sun that is facing Earth, electromagnetic radiation is sent towards Earth. The storm can last minutes or hours.

Scientists aren't sure what causes the Sun to erupt but believe it is correlated with disruptions in the Sun's magnetic field, according to Gizmodo.

NOAA warns that there could be weak power grid fluctuations and there might be a minor impact on satellite operations for spacecrafts. The satellite disruptions could affect things such as GPS systems or commercial flights.

The brightened skies caused by the solar storm will be most visible in Michigan and Maine, according to the NOAA.
