Clear skies but scintillation was bad at times, causing seeing to be variable.  We still report the one Active Region, AR2691, covering 10 millionths with three spots.  Solar Activity remains Very Low with no activity in the last two days.  The nice wide prom is turning closer to the eastern limb and we can see it grow in size above the eastern limb. Another nice prom and a few filaments give the sun some character today.
