Image Details:

The image is a stack of 159 Sun images taken on same number of days during 2022 to highlight the sunspot distibution in two bandss across the solar face. Cloud cover, (plus some work issues and holidays) precluded adding more shots but the increase in the number of days with spots and number of them increased substantially from 2021 to 2022 (as I have that year image too). And it will increase for the next 2 years untill solar maximum some time in 2025.
