Huge, potentially disruptive sunspot will swing round to face Earth this weekend

A huge sunspot on the far side of the sun is set to face Earth this weekend, potentially lashing our planet with a geomagnetic storm. 

The spot is so big it’s changing the way the sun vibrates, according to spaceweather.com. If the dark spot hurls a blob of plasma at Earth, it could disrupt our magnetic field, affecting GPS and communication satellites orbiting close to Earth as well as airplane navigation systems. The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center issued a forecast for an unsettled geomagnetic field around Earth on Aug. 6 and 7, which could means auroras, though whether it becomes a full-blown solar storm is not yet clear.
