https://in-the-sky.org/news.php?id=20240115_16_100 MON, 15 JAN 2024 FROM 13:35 CST (19:35 UTC) TO 16:44 CST (22:44 UTC) The Moon will pass in front of Neptune, creating a lunar occultation visible from Saint Helena. Although the occultation will only be visible across part of the world – because the Moon is so close to the Earth that its position in the sky varies by as much as two degrees across the world – a close conjunction between the pair will be more widely visible. Unfortunately the occultation will not be visible from Austin. The map below shows the visibility of the occultation across the world. Separate contours show where the disappearance of Neptune is visible (shown in red), and where its reappearance is visible (shown in blue). Solid contours show where each event is likely to be visible through binoculars at a reasonable altitude in the sky. Dotted contours indicate where each event occurs above the horizon, but may not be visible due to the sky being too bright or the Moon being very close to the horizon.  Outside the contours, the Moon will not pass in front of Neptune at any time, or is below the horizon at the time of the occultation. However, a close conjunction between the pair will be visible across much of the world. The map can be downloaded in PNG , PDF or SVG format. A KMZ file , is also available, which can be opened in Google Earth to provide a higher resolution map. The animation below shows the path of the occultation across the Earth's globe. The red circle shows where the Moon appears in front of Neptune. animation link: https://in-the-sky.org/news/occultations/animation_occultation_20240115_2111.mp4 A complete list of the countries and territories where the occultation will be visible is as follows: Country Time span (UTC) Saint Helena 22:25–22:37 Lunar occultations are only ever visible from a small fraction of the Earth's surface. Since the Moon is much closer to the Earth than other celestial objects, its exact position in the sky differs depending on your exact location on Earth due to its large parallax. The position of the Moon as seen from two points on opposite sides of the Earth varies by up to two degrees, or four times the diameter of the full moon. This means that if the Moon is aligned to pass in front of a particular object for an observer on one side of the Earth, it will appear up to two degrees away from that object on the other side of the Earth. The position of Neptune at the moment of the occultation will be as follows: Object Right Ascension Declination Constellation Magnitude Angular Size Neptune 23h43m30s 3°06'S Pisces 7.9 0'02" |

Just some trivia.... The lunar eclipse of Neptune is in progress at the time of this post over Saint Helena island which is the only place where it can be seen... which is where Napoleon was exiled after the Battle of Waterloo and where he died. https://en.wikipedia.org/wiki/Saint_Helena |
