Small coronal hole faces Earth

Not a lot of space weather news to report about lately but we do have a small coronal hole facing our planet today. 

Solar wind flowing from this coronal hole could arrive at Earth in about 2 to 3 days from now. Geomagnetic storm conditions (Kp5 or greater) are however unlikely but it could be an interesting event for high latitude sky watchers.
