Lunar Occultation of Venus Promises Stargazing Events in Thailand
The National Astronomical Research Institute of Thailand invites the public to witness a rare lunar occultation of Venus on September 14, 2026.
The lunar occultation will occur between 7:28 PM and 8:34 PM in Bangkok.
Free telescope-viewing events will be held at four regional observatories across Thailand.
Venus will be at its brightest on September 22, 2026, visible until approximately 7:40 PM.
The National Astronomical Research Institute of Thailand (NARIT) has announced an exciting opportunity for astronomy enthusiasts to observe a lunar occultation of Venus on the evening of September 14, 2026. During this event, the Moon will pass in front of Venus in the western sky, creating a spectacular sight for observers across the country, weather permitting.
This rare celestial event is particularly significant as it can be viewed with the naked eye from many locations in Thailand. In Bangkok, the occultation is expected to take place between approximately 7:28 PM and 8:34 PM, with both the Moon and Venus appearing closely positioned after sunset. However, observers will not be able to see Venus re-emerge after the occultation ends, as both celestial bodies will set around 8:24 PM.
NARIT will facilitate free telescope-viewing events at four regional observatories located in Nakhon Ratchasima, Khon Kaen, Chachoengsao, and Songkhla from 6 PM to 10 PM on the night of the event. These sessions will allow attendees to view not only the occultation but also other celestial objects visible that evening. Observers are encouraged to find locations with a clear view of the western horizon, such as beaches or elevated areas, to enhance their viewing experience.
The phenomenon of a lunar occultation occurs when one celestial body obscures another from view. This event can provide valuable data for astronomical research, including measurements of celestial object sizes and distances. The viewing area for such occurrences varies, making them infrequent for specific locations like Thailand. Observers in the country will have a unique chance to witness this event, which is not commonly visible.
As September progresses, Venus will continue to shine brightly in the western sky, known locally as “Dao Pracham Mueang” or the evening star. The planet will reach its peak brightness on September 22, 2026, remaining visible until approximately 7:40 PM. This month promises to be an exciting time for stargazers in Thailand, with the lunar occultation serving as a highlight of the astronomical calendar.
