Heads up, fasten your seatbelts! 💥 A G1-class geomagnetic storm is expected tomorrow July 23rd. While not severe, it may cause disruptions to GPS, satellite communications, and power grids, and some people may feel unwell (e.g. headaches, fatigue).
The storm is being triggered by a fast stream of solar wind coming from a coronal hole, a dark, open area on the Sun’s surface that formed a few days ago. This stream is now interacting with Earth’s magnetic field, causing increased geomagnetic activity.
