A spotless Sun today with good seeing conditions.  A nice filament is visible near the Eastern limb and the plage which is the remnant of AR2744 is approaching the Western limb.  Two reverse polarized areas are visible in the Northern hemisphere.  The largest one just North of the equator at N4.5 degrees and the smaller one at N22.14 degrees.  I made a composite of these regions which will be posted later on the ALPO Solar section website under Transitions of Solar Cycles.
