We compare the free energy computed from the ground-state energy and low-lying excitations of the two-dimensional Wigner solid and the fractional quantum Hall liquid, at magnetic filling factors [nu]=1/7 and 1/9. We find that the Wigner solid melts into the fractional quantum Hall liquid at roughly the same temperature as that of some recent luminescence experiments, while it remains a solid at the lower temperatures characteristic of the transport experiments. We propose this melting as a consistent interpretation of both sets of experiments.
