I imaged the Sun for 365 days between 25 December 2020 and 31 December 2021, missing just six days during this period. The project started with the aim of recording the journey of a single sunspot across the solar disc, but I managed to continue it for a year.
I blended the images to create a single shot, which records the rise of Solar Cycle 25. A total of 127 active regions appeared on the Earth-facing solar disc (AR 12794–AR 12921) during this phase and the image shows all of them. The sunspots create two bands on the solar disc, around 15–35 degrees north and south of the equator and gradually start drifting towards it – a phenomenon known as Spörer’s law.
