>Se= Seeing:
>1 = Clear fine structure in penumbra, granulation very well visible,
> no limb motion.
>2 = Some fine structure in penumbra, small spots within groups easily
> seen granulations visible, slight image motions at limb.
>3 = granulations barely visible, umbra-penumbra limit clear, limb motion
> boiling.
>4 = Umbra and penumbra of large spots seperate, no granulations visible.
> Some bad image and limb boiling.
>5 = Large spots only can be seen, bad boiling, cloud, umbra and penumbra
> cannot be distingushed.
