Analysis of 8,804,545 electron velocity distribution functions (VDFs),observed by the $\mathit{Wind}$ spacecraft near 1 AU between January 1, 2005and January 1, 2022, was performed to determine the spacecraft floatingpotential, $\phi{\scriptstyle_{sc}}$. $\mathit{Wind}$ was designed to beelectrostatically clean, which helps keep the magnitude of$\phi{\scriptstyle_{sc}}$ small (i.e., $\sim$5--9 eV for nearly all intervals)and the potential distribution more uniform. We observed spectral enhancementsof $\phi{\scriptstyle_{sc}}$ at frequencies corresponding to the inversesynodic Carrington rotation period with at least three harmonics. The 2Dhistogram of $\phi{\scriptstyle_{sc}}$ versus time also shows at least twostrong peaks with a potential third, much weaker peak. These peaks vary in timewith the intensity correlated with solar maximum. Thus, the spectral peaks andhistogram peaks are likely due to macroscopic phenomena like coronal massejections (solar cycle dependence) and stream interaction regions (Carringtonrotation dependence). The values of $\phi{\scriptstyle_{sc}}$ are summarizedherein and the resulting dataset is discussed.
