Huge, potentially disruptive sunspots will turn around to face Earth this weekend
A huge sunspot on the far side of the sun is expected to face Earth this weekend, potentially hitting our planet with a geomagnetic storm.
The spot is so big that it changes the way the Sun vibrate, according to spaceweather.com. If the dark spot projects a drop of plasma onto Earth, it could disrupt our magnetic field, affecting GPS and communications satellites in near-Earth orbit as well as aircraft navigation systems. The National Oceanic and Atmospheric Administration (NOAA) Space Weather Prediction Center released a forecast for an unstable geomagnetic field around Earth on August 6-7, which could mean auroras, although it’s not yet clear whether it will become a full-fledged solar storm.
