Clear skies with good seeing.  It has been about a week with clouds, rain, clouds, rain, and so on.  But today the Sun shows that it is still spotless.  We see some prominences and plages near the Eastern rim, but no spots can be seen.  Both areas seem to have Cycle 25 polarization, and the spotless streak stands at 28 days.  Full disk images today in the three wavelengths and close ups in Ha of the two mentioned regions.
