Low fast clouds tracking through, but enough time between them for a quick session with average seeing. Solar Activity remains Very Low on with no flares in the last two days. However we see two small regions with two pores which tomorrow might be named.  These regions are visible in Ha as well as in CaK and the spots are clearly visible in visible light also. In addition, we have a nice filament at the Eastern limb and some prominences at the NE and NW limbs.
