## Content

The study of anisotropic flow provides strong constraints to the evolution of the medium produced in heavy ion collisions and its event-by-event geometry fluctuations. The strength and predominance of these observables have long been related to collective behavior in the formed medium. Recent results in small systems both at RHIC and LHC provide strong arguments for the formation of such medium at those scales. However, for a complete characterization of the phenomena, additional differential measurements are desirable.

PHENIX recorded data from d+Au collisions at 200GeV, 62GeV and 39GeV in 2016 using a special trigger which enriches the data size for collisions that are very central. In this talk, I will show our recent anisotropic flow measurements for fully reconstructed $\pi^0$ at $-0.35<\eta<+0.35$ for d+Au.
