Astronomical Observatory, U. Coimbra, Portugal

Our friend Adriana, from the Astronomical Observatory of the University of Coimbra (OAUC), in Portugal, makes a living from photographing the Sun, and was kind enough to send us these beautiful pictures, in H-Alpha and Calcium II lines:

A much larger archive of (almost daily) solar images can be found in OAUC's webpage.
