Transparency as well as seeing was very bad today with the jet stream above, wind streams moving at opposite directions at different altitudes, as well as wind gusts up to 35 miles/hr.  Solar Activity is Very Low with just two B-class flares in the last two days.  AR2603 disappeared for about one day, but it looks like it is coming back again.  Total active region area for today is 50 millionths with a spot count of 6.  The images today are pretty bad quality because of the observing conditions, but at least they show the progression on the solar disk.  The Ha full disk image was not useable so it is not included.
