Big heat, big freeze

After the turbulent period beginning of November 2004, the solar activity cooled down considerably. No flares reaching the M/X level or halo coronal mass ejections (CMEs) were reported in recent days.  



From November 3 until November 10, Catania sunspot group 61 (NOAA 0696) produced an impressive list of flares and halo CMEs.  The picture on the left taken by the MDI-instrument onboard of SOHO, shows the Sun in visible light. The big black spot in the center of the disk is the number 61, responsible for all excitation including halo-cme-alerts, severe geomagnetic storms, aurora, ...

November 13, the group turned out of view and disappeared behind the west limb. Today, November 16 (figure on the right), the solar disk looks much more simple resulting in low flaring activity and no CMEs.

The Sun continues again the road to solar minimum!
