After mostly cloudy skies yesterday, clear skies this morning with good seeing.  We observe a new, yet not named, sunspot at the Eastern limb. After 7 spotless days we can be tracking a new area again.  The nice filament is still there and the Western limb showed two prominences, on of which was very faint.  Full disk images today in the three wavelengths, as well as close ups of the mentioned areas.
