My first session of the year and decade.  Clear skies with some clouds and below average seeing.  We seem to have a new pore, or area that came around the Eastern limb.  Its location is at a latitude of -35.5 degrees and a longitude of 354.5 degrees.  And guess what?  This one has again reverse polarization.  It was not named in SWPC’s midday discussion, so we’ll see if it makes it as a named active region. A few filaments  and some plages could be observed in CaK, as well as some faint and small proms.  My images today include a close up of the region with two different cameras, a 3x magnification with the ASI174MM and a 2x magnification with the ASI120MM.
