In addition to observing the 15th anniversary of 9/11, there still was some time to observe the Sun.  Today Solar Activity is still very low.  No C-class flares in the last two days.  The four regions, AR2585, 88, 89 and 91 cover a total Active Region Area for the hemisphere of 450 millionths with a total of 26 sunspots.  In addition, the nice filament that made the Sun great to observe the last 10 days or so, is now spanning the Western limb, showing some nice Proms which even show two detached proms!
