Massive coronal hole faces Earth
She's back! That massive coronal hole system that faced us four weeks ago is back and it survived its trip around the farside of our star. This truly gigantic coronal hole managed to cause geomagnetic storming conditions on five consecutive days during the first five days of this month. Fantastic auroral displays were reported from all around the world.
