A minor geomagnetic storm is predicted to occur at some point today as solar winds make their way to Earth from a "hole" in the sun's atmosphere.

Forecasters at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC) said on Monday that G1-strength geomagnetic storms "are likely on 6 July due to a geoeffective coronal hole high speed stream."
