It has been 8 days since I could observe the Sun.  Today we see that a new plage developed in the NE quadrant which has not shown any pores or spots so far, and I did not notice a faculae in WL, although a B1 flare was noticed near its location yesterday. In addition, a nice stream of plasma is visible between the two poles of the region. So we still have a spotless day, but the area is polarized as a Cycle 25 area.  Today full disk images and a close up of the plage in CaK and Ha.
