  We present the results from a high cadence, multi-wavelength observation
campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset
complements the current literature by adding higher cadence as well as extended
coverage of the lightcurve evolution and late-time spectroscopic evolution.
Photometric coverage reveals that AT 2016jbu underwent significant photometric
variability followed by two luminous events, the latter of which reached an
absolute magnitude of M$_V\sim$-18.5 mag. This is similar to the transient SN
2009ip whose nature is still debated. Spectra are dominated by narrow emission
lines and show a blue continuum during the peak of the second event. AT 2016jbu
shows signatures of a complex, non-homogeneous circumstellar material (CSM). We
see slowly evolving asymmetric hydrogen line profiles, with velocities of
500km$s^{-1}$ seen in narrow emission features from a slow moving CSM, and up
to 10,000km$s^{-1}$ seen in broad absorption from some high velocity material.
Late-time spectra ($\sim$+1 year) show a lack of forbidden emission lines
expected from a core-collapse supernova and are dominated by strong emission
from H, He i and Ca ii. Strong asymmetric emission features, a bumpy
lightcurve, and continually evolving spectra suggest an inhibit nebular phase.
We compare the evolution of H$\alpha$ among SN 2009ip-like transients and find
possible evidence for orientation angle effects. The light-curve evolution of
AT 2016jbu suggests similar, but not identical, circumstellar environments to
other SN 2009ip-like transients.
