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 H{alpha} flux from CSM interactions declines, the broad component of H{alpha} 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.2014ApJ...787..163Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/787/163CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7J/MNRAS/433/1312 : SN2009ip UBVRI, UVOT and JHK light curves (Fraser+, 2013)J/ApJ/763/L27 : RI light curves of the type IIn SN 2009ip (Prieto+, 2013)J/ApJ/768/47 : Swift/XRT 0.2-10keV observations of SN2009ip (Ofek+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/787/163https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/787/163http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/787/163https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/787/163https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/787/163http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/787/163GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/787/163/table3 (UBVRI Local Sequence Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/787/163/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/787/163/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/787/163/table3?GETtext/xml+votable180.050000true335.7844583-28.94766670.005555555555555556Cone search capability for table J/ApJ/787/163/table4 (SDSS griz Local Sequence Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/787/163/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/787/163/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/787/163/table4?GETtext/xml+votable180.050000true335.7999167-28.98591670.0055555555555555566/46999 470052.040811542443644e-19 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/787/163?format=asciiOpticalInfrareddefaultJ/ApJ/787/163/table1LCOGT photometry for the 2012-B event of SN 2009ipe_1mVmag?
