It is summer in the northern hemisphere. While solar activity has been very low the past few weeks as we are crawling towards solar minimum, the Sun is actually doing its mighty best here in Europe with scorching temperatures throughout large parts of Europe. However, we were notified today by our very own alert system that we have an interesting solar feature on the Sun today. Indeed you guessed it: a coronal hole is facing our planet today and sending a fast solar wind stream towards us.

Its a fragmented coronal hole stretching from the Sun's south pole all the way to the solar equator. The solar wind stream flowing from this coronal hole is expected to arrive on 24 July and could stir up a minor G1 geomagnetic storm.
