We image vortex creep at very low temperatures using Scanning Tunneling Microscopy (STM) in the superconductor Rh\(_9\)In\(_4\)S\(_4\) (\(T_c\)=2.25 K). We measure the superconducting gap of Rh\(_9\)In\(_4\)S\(_4\), finding \(\Delta\approx 0.33\)meV and image a hexagonal vortex lattice up to close t...
