Utilizing the SDSS-DR13 spectroscopic dataset, we create a newpublicly-available catalog of 1,800 galaxy clusters (GalWeight cluster catalog,$\mathtt{GalWCat19}$) and a corresponding catalog of 34,471 identified membergalaxies. The clusters are identified from overdensities in redshift-phasespace. The GalWeight technique introduced in Abdullah, Wilson and Klypin(AWK18) is then applied to identify cluster members. The completeness of thecluster catalog ($\mathtt{GalWCat19}$) and the procedure followed to determinecluster mass are tested on the Bolshoi N-body simulations. The 1,800$\mathtt{GalWCat19}$ clusters range in redshift between $0.01 - 0.2$ and inmass between $(0.4 - 14) \times 10^{14}h^{-1}M_{\odot}$. The cluster catalogprovides a large number of cluster parameters including sky position, redshift,membership, velocity dispersion, and mass at overdensities $\Delta = 500, 200,100, 5.5$. The 34,471 member galaxies are identified within the radius at whichthe density is 200 times the critical density of the Universe. The galaxycatalog provides the coordinates of each galaxy and the ID of the cluster thatthe galaxy belongs to. The cluster velocity dispersion scales with mass as$\log(\sigma_{200})=\log(946\pm52~ \mbox{km} ~ \mbox{s}^{-1})+(0.349\pm0.142)\log\left[h(z) ~ M_{200}/10^{15}M_\odot\right]$ with scatter of$\delta_{\log\sigma} = 0.06$. The catalogs are publicly available at thefollowingwebsite\footnote{\url{https://mohamed-elhashash-94.webself.net/galwcat/}}.
