Coronal hole faces Earth

While the NOAA SWPC does not look further than three days into the future, we take a look at our Sun with the help of SDO at a wavelength of 193 Ångström (header image). What we can see is that this coronal hole is of a similar size as it was during the previous rotation and that means we should again expect multiple days with enhanced solar wind conditions at our planet. We can extend the minor G1 geomagnetic storm watch which starts this Thursday (22 October) for at least three more days based on the size of this coronal hole and its track record from the previous rotation. Expect enhanced geomagnetic conditions with occasional minor geomagnetic storm conditions all the way until at least Sunday which would be the 25th of October. Charge those camera batteries, we could be in for some very decent auroral displays in the coming days! Good luck!
