Teamwork

A long-duration X1 flare was associated with the strongest proton event so far this solar cycle, as well as with an earth-directed full halo CME. ***UPDATE: The ICME arrived shortly after noon on 24 March, sparking a severe geomagnetic storm.***

NOAA 3599's spectacular eruption

Active region NOAA 3599 had already rotated over the Sun's west limb when it produced a spectacular long duration C-class flare.

Slowly but surely

The polar field reversal on the Sun is ongoing, but it is not completed yet as testified by observations.
