Lunar Occultation Brings Moon and Jupiter Alignment to Saudi Arabia and Global Skies
The Moon and Jupiter aligned in a stellar embrace at dawn on Tuesday in the sky over Arar in Saudi Arabia’s Northern Borders region, as the Saudi Press Agency reported. Viewers with both the naked eye and astronomical telescopes observed the two celestial bodies appearing close together, creating a clear scene made possible by the region’s clear skies and minimal light pollution. A celestial event occurred on November 3, when a lunar occultation caused the Moon to pass directly in front of Jupiter, hiding the giant planet for a little over half an hour before it reappeared on the other side.
Adnan Khalifah, a member of the Space and Astronomy Club, explained that open desert landscapes offer ideal locations for astronomical observation. He noted that a conjunction represents the apparent proximity of two celestial bodies in the sky as seen from Earth, rather than an actual closeness in space, aligning along the same line of sight. Amjad Nasser, an amateur astronomer in Riyadh, told Arab News that the phenomenon offers an ideal opportunity for non-professionals, students, and young people to engage in stargazing and learn about the movements of celestial bodies.

The Moon sits approximately 3.8 lakh kilometers from Earth. When viewed from opposite sides of the planet, its apparent position against distant stars shifts by about two degrees, which is nearly four times the Moon’s diameter. This geometric effect explains why an occultation visible from one location remains hidden from another. The Ooty Radio Telescope of NCRA-TIFR utilized lunar occultations of distant radio sources to provide evidence for Big Bang cosmology during the 1970s and 1980s.
Timing and Visibility Across Global Locations
Specific regional timelines for the November 3 occultation noted that in Bengaluru, the Moon rose at around 1:00 AM, followed by Jupiter a few minutes later, with Jupiter disappearing behind the Moon at 2:30 AM while the Moon sat about 20 degrees above the eastern horizon. Ajay Talwar, Vice President of the Amateur Astronomers Association, New Delhi, said that while Jupiter occultations happen frequently somewhere on Earth, visibility from a specific location remains rare, occurring once every 10 to 13 years or longer. In Koramangala, the expected disappearance times for Jupiter’s Galilean moons were 2:32:24 AM for Io, 2:39:26 AM for Ganymede, and 2:45:34 AM for Callisto, alongside Europa passing in front of the planet.
AlUla Earns DarkSky Certification for Desert Stargazing Hub
Saudi Arabia is actively expanding astrotourism in regions like AlUla under Saudi Vision 2030, launching seasonal nature and heritage initiatives that highlight clear desert skies with low light pollution, Arab News reported. AlUla serves as a premier regional stargazing hub, with DarkSky International certifying sites such as AlUla Manara as International Dark Sky Places. Located within the world’s third-largest Dark Sky Park between Gharameel Nature Reserve and Harrat Uwayrid Reserve, AlUla Manara was designed by Heatherwick Studio—the architecture practice behind Little Island in New York, Azabudai Hills in Tokyo, and Coal Drops Yard in London. Approved by the Royal Commission for AlUla, the landmark draws design inspiration from spiraling geometries found in galaxies, planetary rings, plants, fossils, and shells.
Frequently Asked Questions About the Lunar Occultation
What is a lunar occultation?
A lunar occultation occurs when the Moon passes directly in front of a distant celestial body, such as a planet or star, temporarily hiding it from view due to alignment along the observer’s line of sight.
Are special safety precautions required to watch the event?
There are no special precautions required, and the celestial event is safe to watch with the naked eye, binoculars, or a telescope.
How long does Jupiter remain hidden behind the Moon?
The giant planet remains hidden behind the Moon for a little over half an hour before reappearing on the opposite side.
