200 Days of Sunspots

Continuing on with my solar project, I present to you 200 days of sun. The image shows all the sunspots that has appeared on the earth-facing solar disk over 200 days (25th december 2020-12th July 2021). The image also shows a comparison of activity over a period of 100 days (second row) and 50 days (third row). The good news is that there has been a sharp incline in solar activity in the last 100 days compared to the first phase.
