We report the discovery of a new star cluster, DES 3, in the constellation ofIndus, and deeper observations of the previously identified satellite DESJ0222.7$-$5217 (Eridanus III). DES 3 was detected as a stellar overdensity infirst-year Dark Energy Survey data, and confirmed with deeper photometry fromthe 4.1 metre Southern Astrophysical Research (SOAR) telescope. The new systemwas detected with a relatively high significance and appears in the DES imagesas a compact concentration of faint blue point sources. We determine that DES 3is located at a heliocentric distance of $\sim 76\,\mathrm{kpc}$ and it isdominated by an old ($\simeq 9.8\,\mathrm{Gyr}$) and metal-poor($\mathrm{[Fe/H]}\simeq -1.88$) population. While the age and metallicityvalues of DES 3 are similar to globular clusters, its half-light radius($r_\mathrm{h}\sim 6.5\,\mathrm{pc}$) and luminosity ($M_V \sim -1.9$) are moreindicative of faint star clusters. Based on the apparent angular size, DES 3,with a value of $r_\mathrm{h}\sim 0.\!^{\prime}3$, is among the smallest faintstar clusters known to date. Furthermore, using deeper imaging of DESJ0222.7$-$5217 taken with the SOAR telescope, we update structural parametersand perform the first isochrone modeling. Our analysis yields the first age($\simeq 12.6\,\mathrm{Gyr}$) and metallicity ($\mathrm{[Fe/H]}\simeq -2.01$)estimates for this object. The half-light radius ($r_\mathrm{h}\sim10.5\,\mathrm{pc}$) and luminosity ($M_V\sim -2.7$) of DES J0222.7$-$5217suggest that it is likely a faint star cluster. The discovery of DES 3indicates that the census of stellar systems in the Milky Way is still far fromcomplete, and demonstrates the power of modern wide-field imaging surveys toimprove our knowledge of the Galaxy's satellite population.
