The northern lights could make an appearance in the night sky, weather pending, Monday and Tuesday night. Whether or not Massachusetts could see the aurora varies.

A strong geomagnetic storm will produce northern lights in nearly two dozen US states on Saturday night, the National Oceanic and Atmospheric Administration (NOAA) prediction states. The forecast map and typical aurora visibility patterns during a G3 storm show that states from the Pacific Northwest to the Northeast will see the aurora borealis under favorable weather conditions.

A period of peak magnetic storms on the sun could lead to another show of northern lights on Earth on Saturday and Sunday, forecasters say.
