Clear skies during my observing session with average seeing.  Another spotless day for the Sun.  The two proms at the Eastern limb are still there and one can see a plage associated with each of them near the rim.  Both of them seem to have Cycle 25 polarization.  Its worth to keep an eye on these two.  Full disk images as well as close ups in Ha of the two proms/plages.
