NOAA SWPC issues minor G1 storm watch

The NOAA SWPC has issued a minor G1 geomagnetic storm watch for this Friday, 19 October.

This is likely due to the fact that a small southern extension of the northern hemisphere polar coronal hole is facing our planet today as you can see on our header image which comes from NASA's Solar Dynamics Observatory.

This same coronal hole did briefly cause minor G1 geomagnetic storm conditions last month but compared to the last rotation, this southern extension diminished in size and we doubt that G1 storm conditions are possible this time around. Nonetheless it is something to keep an eye out in the days ahead if you are a sky watcher at a high latitude location.
