Erie, Pa. (WJET/WFXP/ — A strong geomagnetic storm caused the Northern Lights to be visible over Lake Erie Thursday night into Friday morning.

The National Oceanic and Atmospheric Administration (NOAA) reported a strong geomagnetic storm (G3) disturbed the Earth’s magnetic field on Thursday. There was no cause for public concern, but the aurora borealis or Northern Lights were visible for Canada and most of the northern United States around 10:45 p.m. Thursday.

Over Lake Erie, the aurora was visible just above the horizon.

Geomagnetic storms do cause some minor effects on technology. This particular storm had the possibility to effect the power grid, spacecraft operations and GPS, according to the NOAA.

While the sky was mostly overcast Thursday night in Erie County, the Northern Lights were visible in some areas. Other parts of the country had better weather for viewing, such Michigan’s Upper Peninsula.
