In 2024, two astronomical events that have escaped our attention are the summer-solstice or summer solstice and the Strawberry Full Moon. The 2024 summer solstice will occur on June 20 2024 at 20:05 UTC or June 21 2024 at 03:05 WIB, and the Full Moon will occur on June 22 2024 at 01:08 UTC or June 22 2024 at 08:08 WIB. The Strawberry Full Moon is a full moon that occurs in June, so called because at this time the people can pick strawberries, which grow wild in the forests of North America.
We celebrate the summer solstice and Full Moon events in 2024, which are only 1 day apart, by holding a Full Moon Festival event initiated by BRIN and in collaboration with several universities, including ITB, UI, UGM, and Unwar, by inviting elementary, middle, high school, college students and the general public around Borobudur Temple. This event is also used to witness the moment the sun sets in the west and a moment later the full moon rises in the east-southeast, which occurs once every 18-20 years.
Popularizing Astronomy to the lay public, elementary, middle school, high school and college students in the area around Borobudur Temple by providing an understanding of the existence of Borobudur Temple and its relationship to astronomical phenomena. Re-measure the orientation of the Borobudur Temple building by utilizing the position of the Summer Solstice or North Solstice of 23°5 N. Excavating ethno-archaeoastronomic remains in the villages around Borobudur Temple, especially the bencet or gnomon, pranotomongso and the seven circles found on the reliefs of Borobudur Temple
Helping students to understand the position of a place on the Earth's surface and celestial bodies on the celestial sphere, as well as understanding the Full Moon phenomenon. Educating the public about an astronomical phenomenon that they may have never imagined, namely in the evening seeing the sun setting in the west and seeing the moon rising in the east-southeast. Helping ordinary people, including elementary, middle, high school and university students, to understand that no building or artifact was built haphazardly, almost everything is full of astronomical information, and to understand that the knowledge of our ancestors was very advanced.
