KIC8462852 Hereford Arizona Observatory Photometry Observations Bruce Gary, Last updated: 2017.09.28, 05 UT

"The September fade event has recovered. It lasted from Sep 5.5 UT to Sep 16 UT, and reaching a depth of ~ 2.3 %."[2] - as/of 16 September 2017, a "2.3%"[2] (or a "3%")[3] dimming.

Light curve for "May to now [28 September 2017]" for HAO V-band and g'-band observations, with an adjustment for an "Inverse Gaussian" model for the long-term variation/fade of OOT brightness (described below). Starting Sep 21, when g'-band replaced V-band observations, an empirical adjustment was made to all previous V-mag's (adding 0.179 mag).

Note: g'-band and r'-band dip depths (and shapes) may differ, with g'-band being more sensitive to dust cloud scattering due to its much shorter wavelength. It appears that a dip has begun at g'-band, which is not present r'-band (Fig. 3). None of these shapes resemble exo-comet tail transits (as described by Rappaport et al, 2017 link); so the mystery of what's producing these week-timescale dips continues!
