Clear skies for a change, but cold.  Another spotless Sun today. A few small proms were visible in Ha in the NE, and filaments in the NW quadrant.  A very small bi-polar area could be seen in the West in SDO’s magnetogram, and also in the CaK wavelenght, but it seemed to have Cycle 24 polarization.
