sun behind clouds

after 3 covered days, the eastern hemisphere of the sun is seen blank, the complex AR3852-54 is dead center while the other two groups are close to exit the sun face; again, two big active regions are gaining strength in the farside, think we can expect to see them in a week or so; poor contrast due to high clouds.
