Indonesians in Siak near Riau, Singkawang in West Kalimantan and Nias in North Sumatra were able to observe the full annular solar eclipse on Thursday. An annular solar eclipse happens when the Moon covers the Sun's center and a "ring of fire" shows up on the outer edges of the Moon. It occurs once every two years. The last annular solar eclipse in Indonesia happened on Feb. 26, 2017.
Thursday's annular solar eclipse was observable from 25 cities in western and central parts of Indonesia – from Sinabang in Aceh to Putussibau in West Kalimantan. Jakartans were only able to see a partial (70 percent) solar eclipse.
According to the Meteorology, Climatology and Geophysics Agency (BMKG), the annular solar eclipse was observed for the longest time in Selat Panjang, Riau, for a total of 3 minutes and 38.9 seconds.
