In some "dust fading" objects, short-term variations (less than 1 hour)
are suspected. Some of these variations are considered to reflect transient
dust formation and destruction(?) [I read this in some recent book, but
don't have a bibliographic reference]. It is not yet obvious whether
oversampled observations are useless.
