23June2022: The Fraunhofer Four

Post by p_zetner »

Hello Everyone.

Here is a collection of images from my spectroheliography session of 23 June. The montage shows three chromospheres (hydrogen, calcium and helium) in four lights: Ca H (396.85 nm), H beta (486.13 nm), He D3 (587.56 nm) and H alpha (656.28 nm). These are the Fraunhofer H, F, D3 and C lines respectively.

Cheers.
Peter
