A Geminids meteor shower is due on Wednesday night and, weather permitting, it can be seen from all regions in areas without too many lights.
Viewing events are scheduled in Chiang Mai, Nakhon Ratchasima and Chachoengsao provinces.
In Chiang Mai, it will be at Huay Lan Reservoir on Wednesday night, arranged by the National Astronomical Research Institute (NARIT) and in San Kamphaeng district.
NARIT's senior director said the Huay Lan Reservoir area has been chosen because it was suitably dark and without disturbing lights.
Activities would include a lecture on basic stargazing and techniques for photographing the meteor shower. Attendees could view the meteor shower through telescopes.
Elsewhere, viewing will be available at two observatories - Suranaree University of Technology in Nakhon Ratchasima province, and in Plaeng Yao district, Chachoengsao province.
However, people can see the Geminids meteor shower - named for the constellation Gemini - in all regions from an area with complete darkness.
The Geminids meteor shower occurs from Dec 4-20 every year. This year, astronomers predict a major display on the night of Dec 14, with about 150 meteors per hour.
