The NOAA SWPC has issued a minor G1 geomagnetic storm watch for 5 August (Monday) due to a coronal hole that is facing our planet today.

This transequatorial coronal hole is a bit larger than the previous coronal hole that faced Earth so its not strange that NOAA expects a stronger geomagnetic response once the solar wind stream arrives. The NOAA SWPC expects minor G1 geomagnetic storm conditions on Monday which would be the first geomagnetic storm since almost a month if it materializes of course. With dark night skies slowly returning in the northern hemisphere this could be the first opportunity of the new aurora season for many of our visitors. Good luck!
