Cloudy and rain for a few days, so today is a makeup day.  This is my 1700th blog discussing astronomy.  Today’s topic is the reversed polarized area that popped up January 1st and in the meantime has been named AR2755.  This is nice, we have a new region on the first day of the first year of the decade during solar minimum. This area is also reverse polarized, making it consistent to a Cycle 25 area.   Since I took the time Wednesday to make close ups of the WL and Ha images, I put together a composite showing three images of the area together with an SDO HMIB magnetogram image to document this event .  Apologies for the quality caused by many issues, starting with a jet stream with wind sheers of 100 miles/hour above.
