Details:
A preview of things I captured today. Here is the new active region of september 21st 2020. Over the limb the magnetic loop structure is clearly visible in the wavelength of 393.37nm which represents the "singly ionized calcium K3 core"
These were captured through the wildfire smoke that has blanketed the midwest skies.
