Transition of Sunspot AR2786

Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas. They are regions of reduced surface temperature caused by concentrations of magnetic field flux that inhibit convection, in this new Solar Cycle 25, the sun has started showing various groups of sunspots, active regions, and prominences, this image of photosphere is a collage of a huge sunspot AR2786 showing its orientations and progression as our sun rotates, the size of the sunspot is much bigger than the total diameter of the four terrestrial planets.

Here is the true North & East direction markings on sun.
I divide the whole Solar Disk into Graticules, with 10° difference between each Meridian & Parallel. From this we can easily identify that the AR2786 emerged from the South-Eastern limb & moved towards the South-Western limb of Sun (counter-clockwise rotation of sun). Also i have marked a distance arrow just above the giant Sunspot of Day 8 (middle one), which indicates that it's relative size is even more than the total diameter of four rocky planets: Mercury, Venus, Earth & Mars.
