The USAP Portal: Science and Support in Antarctica - South Pole Station Webcams or here: ESRL Global Monitoring Division - South Pole Observatory

Of course if the moon is obscured by a heavy overcast on the day it might be a different story.

The standard algorithms for moonrise/-set are a bit whacky for these extreme longitude values, but indeed between 2016/6/13 08:05:02 and 2016/6/27 12:53:52 the moon ist astronomically above the horizon: https://gist.github.com/cprior/c295bbb24d00897b73d21f574e862b2e

Fascinating!
