 EPOD - a service of USRA

The Earth Science Picture of the Day (EPOD) highlights the diverse processes
and phenomena which shape our planet and our lives. EPOD will collect and
archive photos, imagery, graphics, and artwork with short explanatory
captions and links exemplifying features within the Earth system. The
community is invited to contribute digital imagery, short captions and
relevant links.


 A Year of Sunspots

   November 10, 2022


    A Year in the Sun (1)

   Photographer:  Soumyadeep Mukherjee
   Summary Author:  Soumyadeep Mukherjee

   I imaged the  Sun for 365 days between December 25, 2020, and
   December 31, 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 disk, but I managed to continue imaging
   for an entire year. From my home in Kolkata, India, 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 disk (AR 12794–AR 12921) during this phase – the image above
   shows all of them.

   Two  bands of sunspots can be identified moving across the solar
   disk, around 15–35 degrees north and south of the equator. Note that
   they gradually start drifting towards the solar equator – a phenomenon
   known as  Spörer’s Law.
   Photo details: Nikon D5600 camera; Sigma 150–600c lens; Thousand Oaks
   Filter (White-Light); f/6.3; ISO 100; 365 individual exposures
   (1/80-second to 1/500-second), 600mm; Post-processing using PIPP and
   Photoshop.
