Coronal hole faces Earth
Space weather has been very quiet for weeks now. Solar activity has been very low (A and B-class activity only) ever since 19 April and the last geomagnetic storm was a long time ago as well: 23 April. There were pretty much no interesting space weather events to report since that time but today we finally have something interesting to report. It might not be the biggest news we have ever brought to you (literally) but we take anything at the moment! It is a small coronal hole that is facing our planet today and it is now sending an enhanced solar wind stream towards us which could spark some nice aurora in a few days from now.
