Three large explosions from the Sun over the past few days have prompted U.S. government scientists to caution users of satellite, telecommunications and electric equipment to prepare for possible disruptions over the next few days.
"The magnetic storm that is soon to develop probably will be in the moderate to strong level," said Joseph Kunches, a space weather scientist at the Space Weather Prediction Center, a division of the U.S. National Oceanic and Atmospheric Administration (NOAA).
He said solar storms this week could affect communications and global positioning system (GPS) satellites and might even produce an aurora visible as far south as Minnesota and Wisconsin.
An aurora, called aurora borealis or the northern lights in northern latitudes, is a natural light display in the sky in the Arctic and Antarctic regions caused by the collision of energetic charged particles with atoms in the high altitude atmosphere.
Major disruptions from solar activity are rare but have had serious impacts in the past.
