@wonderofscience I recently read the fascinating book, “Madhouse at the End of the Earth: the Belgica's Journey into the Dark Antarctic Night” by Julian Sancton. It frequently discusses the sun’s position & duration above the horizon during the months it IS above the horizon, because getting to experience any sun at all was so crucial to the crew’s mental & physical wellbeing & ability to function. So it’s very cool to get to see this!
