The NOAA SWPC has issued a minor geomagnetic storm (G1) watch for this Thursday (22 October) as a high speed solar wind stream from the northern polar coronal hole is expected to arrive at Earth. This is the same coronal hole which caused multiple days with geomagnetic storm conditions (G1-G2) last month and produced solar wind speeds around 650km/s at our planet.
