High Cirrus clouds and contrails today.  AR2729 is growing, and covers 30 millionths and 6 spots, but has not produced any flares so far.  Just North of it at a latitude of 10 degrees North, I saw a very small area in CaK and Ha, which showed Cycle 25 polarization in the SDO magnetograms.  However at this low latitude it is questionable if it might become a Cycle 25 area. Images today in all three wavelengths as well as close ups of AR2729 in Ha and WL.
