Observations of KIC 8462852 (aka Boyajian's Star) reveal a yearlong fade pattern that is remarkably similar to the fade pattern derived from Kepler mission observations. The ground-based observations reported here can be described as a gradual fade that ended in late 2016 with the beginning of a yearlong U-shaped fade of 1.1 percent. Near the end of this U-shaped fade a series of very brief dips occurred. The Kepler data exhibit a similar pattern 1600 days earlier, except with an abrupt end of observations before the U-shape recovery. Observations lasting many years are needed, especially during our predicted repeat of the U-shape and short dip pattern in 2021.
