It has been two weeks since my last observing session.  During that period, SWPC reported one spotless day for June 12th.  However the next day AR2833 came around the Eastern limb and was named.  It covered an area of  140 millionths.  Today it remains the only spot on the Sun as an Hsx.  In addition, a nice prominence was observed at the Eastern limb just a little North of it.  A second prom could be seen at the SW limb.
