This is sunspot AR2835 that’s just starting to come around to the earth facing side of the sun (the sunspot is at the far left of the sun in this image):
This sunspot is actually made up of three active regions, not visible in this image. It is of bipolar polarity, which means it shows both positive and negative polarity with a simple division between poles.
Also barely visible in the preceding image is a prominence at about the 7 o’clock position of the sun; there are also filaments to the right of the active region.
This is the sun as it appeared on June 28, 2021, featuring AR2835 at the upper-left and AR2836 to the right and slightly below:
AR2835 has changed and now has four active regions and AR2836 also has four active regions. AR2836 is also a bipolar region, meaning that it has both positive and negative polarity.
As of June 29, 2021, AR2835 is now 12 active regions:
AR2835 is the upper active region.
AR2836 is the lower active region in the preceding image and now has nine active regions, and it is also a bipolar region.
These active regions join a third one that’s located on the upper half of the sun.
As of June 30, 2021, AR2835 is now made up of 16 active regions and features a structure called Ellerman Bombs, as shown in the second image below:
Ellerman Bombs are magnetic explosions that occour because opposite polarity regions are colliding near the sunspot. These types of collisions could lead to the eruption of a solar flare.
I took these images using the Slooh.com Canary Five solar telescope.
