Massive coronal hole approaching Earth
A giant coronal hole on the Sun is turning toward Earth and is set to blast high-speed solar wind our way around June 25.
NOAA says this could cause geomagnetic storms, which might mess with satellites and radio signals for a bit.
Coronal holes are just cooler, darker spots where the Sun's magnetic field lets solar wind escape more easily.
The Sun has been active lately
The Sun's been showing off with lots of big solar flares and eruptions from sunspot 4100 over the past month.
One recent flare even lit up skies with auroras worldwide and briefly disrupted satellite connections.
It is noted that when these coronal holes mix with other eruptions, storms can get stronger.
NOAA's forecast for June 25-26
NOAA expects mild (G1-class) geomagnetic storms, which could make northern lights visible in higher-latitude areas on June 25-26.
Space weather teams are keeping an eye out and will update if things change—so if you're up north, check local forecasts for your best shot at catching some auroras!
