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.

The seeing was below average today.  The new area was named, and today we have two areas at the Eastern limb:  AR2785 and AR2786.  AR2783 is still on its way to the Western limb, while AR2784 is sizzling out. Full disk images today with close ups of the mentioned regions.

Clear Skies this morning.  AR2783 did produce a C class fare yesterday but has not changed much.  We also have a new not named region with two spots in the NE quadrant.  In addition the prediction center reports two areas of activity around the SE limb which is to arrive in 2-3 days.  A lot of activity might be coming up next week,  Today full disk images of the full disk and close ups of the two mentioned regions.

Clear skies this morning.  AR2783 keeps rotating further onto the Solar disk.  Activity is very low so there is not much change.  Today again the full disk images and close ups of AR2783.

Clear and stable skies this morning.  AR2783 has rotated further onto the visible solar disk.  I see two very small pores to the NE of the spot in the WL close up only.  We will have to wait to see what comes from this.  Full disk images in the three wavelengths as well as close ups of the Region.

Clear skies this morning.  The new Hsx spot that emerged yesterday from the Eastern limb has been named as AR2783 and covers 30 millionths.  It has not much changed since yesterday and we will be keeping an eye on it in the coming days.  Sorry for the over exposure in the CaK closeup.

Clear skies again.  The plage which started to rotate into view yesterday at the Eastern limb seems to contain a new yet unnamed spot.  One can nicely make out the penumbra as well as a light bridge in the WL closeup.  We’ll see if it gets named today, so we can start tracking it again.

Clear skies and cold.  However, the spots are gone.  What’s left is the plage from AR2782 and another plage near the SE limb.  Today full disk images in 540nm, Ha and CaK.
