After more than a week of horrendous geomagnetic activity, due mainly to coronal-hole streaming, it looks as if things are starting to settle down once again. One would never know it from looking at the sun's image as the source of the streaming is largely invisible in the visible light spectrum. Viewing at a different wavelength however, reveals the source of the disruption, now about to rotate out of view for a few weeks.
