The active region AR3545 first emerged on January 9, 2024. Despite not showing much growth as it turned towards the Earth, the size of the main sunspot remains an eye-catching 3-Earth diameters. On a rare second clear day in a row, the brief moment of good seeing with newly improved equipment had made it possible to capture a clear view of the active region with the huge sunspot.
