This interesting article, Rocket launch investigates a polar mystery | Register | The Times , printed in The Times on 4th Dec 2021, talks about a NASA rocket to explore the Polar Cusp. It mentions the ‘Hole’ which appears around noon each day. One of the few ‘Comments’, if you can unload them, asks “How do you know when it’s Noon at the Pole at the Summer Solstice?”.
From a celestial point of view, might the Polar Cusp affect atmospheric refraction when the body is opposite side of the Pole to the observer? DaveP
