This is a remarkable microlensing event because its source is photometrically bright and variable, which makes it possible to perform an asteroseismic analysis using ground-based data. We find that the source star is an oscillating red giant with average timescale of $\\sim 9$ d. The asteroseismic analysis also provides us source properties including the source angular size ($\\sim 27~\\mu{\\rm as}$) and distance ($\\sim 11.5$ kpc), which are essential for inferring the properties of the lens.
