Coronal hole faces Earth, G1 watch issued
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.
