Well, the old AR2738 came back around and was named yesterday as AR2740.  That brings a spotless streak of 13 days to an end. In addition, a small but nice reverse polarized area could be observed in Ha and CaK at 28 degrees North near the meridian.  Today full disk images and close ups of the mentioned areas.
