24 hour sun in Antarctica can be worked into the FE model, and the AE map, if you add a dome to it. The sun is a projection on the dome, an apparent position, not the true position. Getting data, making observations is generally a good thing, as the truth does not fear investigation; understanding how certain optical effects work on a dome is a win for biblical FE, where the firmament is described as molten looking glass, spread out like a tent.
