- If you want my opinion this is PX. It is cleearly seen at the South Pole. I have looked on my sky map and the moon and other planets are not in that position. So! And it is too big to be a UFO.
In the archive, you can try July 9 for example, and see the same object at about the same time it is seen August 6.
- View would be dusk for Australia? Planet X sets to the left of the Sun, in Second Sun photos, so the placement would be right. The Sun angle is from lower left, and as the Moon orbits the Earths equator, this object seems a bit south to be the Moon.
