A Year in the Sun.
A project that started with tracking a single sunspot for 7 days continued for an year and this image is the final result of an year-long project.
I took an image of the sun for 365 days in a row (from 25th December 2020 to 31st Decmeber 2021, except for 6 days due to complete cloud cover).
This image is a blend of all the 365 images showing all the sunspots (AR12794-AR12821) that appeared on the earth-facing solar disk.
Each image was aligned with reference to the SDO images of the respeactive days.
