The Dutch Observatory

Well I was wrong, SWPC did see the spot yesterday and carried it for another day.  So yesterday was not a spotless day.  I was not able to make out the spot today, so we’ll see what happens.  Anyway, I made some close ups in Ha and Cak.  Two of the Ha close ups have been made with the ASI120MM and a 2x barlow.  The other with the ASI174MM and a 3x.

Clear skies this morning.  The Sun seems to be spotless again.  AR2755 looks like it decayed to a plage.  In addition, we see some filaments to the East of the area, as well as in the NE.  A nice prom extends from the SW limb in Ha and some smaller from the NW and SE limbs.

I didn’t expect to image today, but just before our roof would cast its shadow on the location from where I image, a few smaller holes in the fast moving clouds showed up, allowing me one image with the SVC80. And now it rains again….. It looks like we still have one area with one spot. I wonder if this still will be there by tomorrow.

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.

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.
