Despite its size ar11582 has been a quiet active region in the previous days, however now as it nears the limb still sports a delicate light bridge across its centre. It displays the Wilson effect quite well, and appears quite foreshortended and elliptical due to the shallow angle we are now observing it from on Earth. Taken with the 127mm PST mod @ 1900mm fl with the DMK31.
