The Dutch Observatory

Clear skies this morning before the clouds and rain arrives, but the seeing conditions were rather poor.  The plage of AR2791 is ready to turn to the far side.  AR2792 did produce a C4 class flare and AR2793 a few B-class flares.  Otherwise the sun’s activity is low.  A few nice prominences did show in the SE and NW.  Today full disk images and closeups of the mentioned regions.

A short session before the clouds returned.  AR2790 is rotating out of view.  A new area is rotating in sight at the Eastern limb as a plage.  However you never know what tomorrow will bring.  Full disk images today in the three wavelengths as well as close ups of the mentioned areas.

Clear skies this morning with good seeing.  AR2790 is moving fast on its way to the Western limb, it won’t be long and we will not see her anymore.  Go back and look at the size of AR2783 at the beginning of the rotation and the size of AR2790 now.   Wondering what’s next in store….

Clear skies with good seeing today.  Solar activity is Very Low.  AR2790 has not much changed today and remains an Hsx area and covers 50 millionths.  I noticed a very small pore in the small plage near the NW limb.  Today close ups of these areas as well as full disk images.

Clear skies, but the seeing was not good in 540nm and the image was dancing around during the capture.  AR2791 has decayed to a plage and a new plage near the NW limb is visible.  I wonder if it still might be developing a pore or spot.  AR2790 has not changed much.  Today full disk images and close ups in the three wavelengths.

Observing conditions were reasonable except for the seeing which was poor.  We now have three active regions with spots:  AR2785 and AR2786, just beforethey disappear to the far side, and AR2790.  All other regions which were named, have now decayed to plages.  I added images of AR2787 which still shows nice as a plage in the northern hemisphere in Ha and CaK.  I tried to include the other regions as part of the captures.

A very cold observing session this morning with lots of very fast moving clouds and terrible seeing.  AR2785, 86 are still visible and we have a new named area AR2790 near the SE limb.  The other areas have decayed to plages.  Because of the bad seeing conditions I cut my observing session short and only show images in 540nm and Ha.

Was able to have another Solar session in average seeing.  The Sun looks great with 5 active regions.  AR2783 will be leaving the visible disk soon, as well as the plage from AR2784.  Both AR2785 and 6 and 7 have shown some activity over the last day, but have not changed in size much. AR2786 did loose some area since the 26th, when it was 1000 millionths.   I checked back in my database, and it has been since 9/8 and 9/9/2017 since we had an area that covered an area of 1000 or larger of the visible solar hemisphere.  This was when AR2673 reached 1000 and 1060 millionths.  That’s over 3 years ago.  This is well shorter than the the same time for the previous Solar minimum.  Today full disk images again and close ups of some of the regions.

Today  a new area at the NE limb was named as AR2787, while AR2784 still can be seen as a small plage close to the NW limb..  I could observe a tiny spot in AR2787.  AR2786, which covered yesterday 1000 millionths, covered 800 millionths today.  This is the most interesting Sun in a long time.  Today full disk images as well as close ups of the mentioned regions.

Clear skies this morning.  AR2785 and AR2786 are rotating further onto the visible disk of the Sun.  AR2786 looks like the largest sunspot we have seen todate and the Wilson effect is nicely visible in both Ar2786 as well as in AR2785.  An exciting Sun today.
