Another day with clear skies and average seeing.  Whereas yesterday I could make out the faculae associated with AR2739, today the Sun was totally blank for spotless day 428 since solar max.  However, the proms that could be seen at the NW limb yesterday showed up higher today as it seems to be turning from the far side of the sun towards the visible hemisphere.
