These data were collected primarily with the new robotic capabilities of the Las Cumbres Observatory Global Telescope Network, a specialized facility for time domain astrophysics, and includes supporting high-resolution spectroscopy from the Southern Astrophysical Research Telescope, Kitt Peak National Observatory, and Gemini Observatory. Based on our nightly photometric monitoring, we interpret the strength and timing of fluctuations in the light curve as interactions between fast-moving ejecta and an inhomogeneous circumstellar material (CSM) produced by past eruptions of this massive luminous blue variable (LBV) star. Our time series of spectroscopy in 2012 reveals that, as the continuum and narrow Hα flux from CSM interactions declines, the broad component of Hα persists with supernova (SN)-like velocities that are not typically seen in LBVs or SN impostor events. At late times, we find that SN 2009ip continues to decline slowly, at ≲0.01 mag/day, with small fluctuations in slope similar to Type IIn supernovae (SNe IIn) or SN impostors but no further LBV-like activity. The late-time spectrum features broad calcium lines similar to both late-time SNe and SN impostors. In general, we find that the photometric and spectroscopic evolution of SN 2009ip is more similar to SNe IIn than either continued eruptions of an LBV star or SN impostors but we cannot rule out a nonterminal explosion. In this context, we discuss the implications for episodic mass loss during the late stages of massive star evolution. Description: Photometric monitoring of SN 2009ip began on 2012 September 22 with the spectral camera on Faulkes Telescope South (FTS, Siding Spring Observatory, Australia) in filters g'r'i'. The spectral camera is a 4096x4096 pixel Fairchild CCD with a 10.5' field of view. As Faulkes South monitored the rise of SN 2009ip, LCOGT's first three southern 1 m telescopes arrived on site at Cerro Tololo Inter-American Observatory in Chile. Photometric monitoring of SN 2009ip from CTIO began when the telescopes were operational, about one month later on UT 2012 October 21, with the first generation deployment camera: SBIG CCDs with a 15' field of view.
