There was an unprecedented opportunity to study the inner dust comaenvironment, where the dust and gas are not entirely decoupled, of comets45P/Honda-Mrkos-Pajdu\u{s}\'akov\'a (45P/HMP) from Dec. 26, 2016 - Mar. 15,2017, and 46P/Wirtanen from Nov. 10, 2018 - Feb. 13, 2019, both in visiblewavelengths. The radial profile slopes of these comets were measured in the Rand HB-BC filters most representative of dust, and deviations from a radiallyexpanding coma were identified as significant. The azimuthally averaged radialprofile slope of comet 45P/HMP gradually changes from -1.81 $\pm$ 0.20 at 5.24days pre-perihelion to -0.35 $\pm$ 0.16 at 74.41 days post perihelion.Contrastingly, the radial profile slope of 46P/Wirtanen stays fairly constantover the observed time period at -1.05 $\pm$ 0.05. Additionally, we find thatthe radial profile of 46P/Wirtanen is azimuthally dependent on theskyplane-projected solar position angle, while that of 45P/HMP is not. Theseresults suggest that comet 45P/HMP and 46P/Wirtanen have vastly different comadust environments and that their dust properties are distinct. As evident fromthese two comets, well-resolved inner comae are vital for detailedcharacterization of dust environments.
