A 24 hour moon (also called a continuous polar moon) is the lunar cousin of the midnight sun: at high latitude, when the Moon's declination allows it, the Moon can stay above the horizon for about half a lunar month, roughly fourteen days, while its phase changes and it circles the sky. At the geographic South Pole that means one long, unbroken stretch of moon visibility rather than a daily rise and set.
The Final Experiment later filmed the better-known 24-hour Antarctic sun. This page is about an earlier polar-sky record: a 2016 South Pole moon timelapse, not TFE footage.
Robert Schwarz, South Pole 2016
In March-April 2016, photographer Robert Schwarz recorded a fourteen-day moon timelapse at Amundsen-Scott South Pole Station (the geographic South Pole). He published the result on Vimeo as changing phase - the moon over the South Pole
on 14 April 2016.[1]
His field blog tracks the same run:[2]
- 2016-03-09: project starting around sunset: a two-week moon phase-change timelapse, with an Arduino stepper planned for the mount.
- 2016-03-28: sun gone; refraction still seen the night before.
- 2016-04-14: full write-up of the completed fourteen-day run (same substance as the Vimeo description), upload day.
- Moonrise and moonset calendar for South Pole, March 2016 (timeanddate.com)
The filming window can be pinned from those sources rather than left as a vague late-March / early-April span. timeanddate's South Pole moonrise calendar for March 2016 places a moonrise around 23-24 March. The 28 March blog note that the sun was already gone coincides with the video opening on a quite bright sky that then darkens - sunset into the prolonged polar-night stretch - which confirms which moonrise he filmed: the rise beginning 2016-03-24 and running through 2016-04-06, not an earlier continuous-up period. The later blog write-up and Vimeo upload on 2016-04-14 document the completed fourteen-day run after it finished.
Setup, from his own description of the completed run:[1][2]
- Arduino stepper on an old tracking mount
- Continuous operation around −60 °C; heated camera and lens; vacuum-oven dried gear
- 70 mm lens (~22.5° horizontal FOV); Moon's maximum elevation about 18.5°; highest moon cut off in frame
- Weather imperfect; mount stuck on cables twice and needed a daily rewind
- Phase changes while the Moon circles the horizon relative to the Sun; Moon is about fourteen days above (and below) the horizon at the Pole
Primary sources: the Vimeo upload[1] and the South Pole 2016 blog[2].
moon phases 2018
Robert Schwarz, publishing as polarlights, returned to the South Pole in winter 2018 after a failed 2017 attempt. His moon phases 2018 remake shows the Moon changing phase while it stays above the horizon for about two weeks.
Anthony Powell 24-hour moonlight (Scott Base)
Anthony Powell documented continuous winter moonlight at Scott Base in a YouTube TFE package and a LinkedIn post. The Moon makes an elevation wave there, because Scott Base is not at the geographic South Pole.
Moonrise & Meteors
Aman Chokshi's Moonrise & Meteors is a 36-hour timelapse from Amundsen-Scott. The HD video shows the Moon circling parallel to the horizon.
The Moon over the Pole
Robert Schwarz's The Moon over the Pole uses daily captures from a roughly June 2015 South Pole moon-up stretch. It is not a tracked continuous path like his 2016 and 2018 videos.
South Pole tracking mount - part 2 - rising moon & Iridium
In South Pole tracking mount - part 2 - rising moon & Iridium, Robert Schwarz shows the Moon rising on a tracking mount around July 2016. It is a short tracking-mount demonstration, not a multi-day continuous showcase.
Why it matters
Continuous polar moon visibility is expected on a globe at high latitude when the Moon's declination puts it in the sky for that long. It is the lunar version of the midnight sun, not a mystery. Some flat-earthers treat a "24-hour moon" as a globe-killer (see e.g. mentions on ShandTV); a South Pole timelapse of the Moon changing phase while it stays up for half a month is what the globe already predicts.
