KIC 8462852 also
dips in brightness, but
in a much more abnormal way; its
brightness will
dip by as much as 20 percent for
irregular periods of time — anywhere between five to 80 days.
What's so spectacular about WTF's
brightness is that there is a single, smooth
dip in brightness followed 700 days later by
irregular but large decreases that lasted for 100 days before the
brightness returned back to normal levels.
