The Spring Equinox Sun.  Clear Skies and the Jet Stream retracted to the great lakes area giving us good seeing conditions.  Solar Activity remains Very Low.  Another Spotless day.  A few nice filaments are visible in Ha, and the WL images again show granulation! Some nice and faint prominences, but too small and dim for the SM40.
