Jakarta: Indonesia will experience several solar eclipses in 2023. Solar eclipses occur when the Sun’s rays are blocked by the Moon, the Moon’s shadow will fall on Earth.
“The area on Earth that is under the shadow of the core (umbra) of the Moon will experience Total Solar EclipseMeanwhile, areas on Earth that are under the penumbra will experience a partial solar eclipse,” explained the researcher from the Space Research Center, National Research and Innovation Agency (BRIN), Johan Muhamad, quoted from the brin.go.id page, Monday, January 30, 2023.
Indonesia has experienced several solar eclipses, namely in 1983 there was a total solar eclipse, an annular solar eclipse in 2019, and a total solar eclipse in 2016.

The Hybrid Solar Eclipse is expected to occur April 20, 2023. The Hybrid Solar Eclipse is a solar eclipse that appears from some parts of the Earth as a total solar eclipse, but in other areas it appears as an annular solar eclipse.
Johan explained that the solar eclipse that will occur on April 20 2023 in Indonesia is a very special eclipse because it is a rare hybrid solar eclipse. In Indonesia, this solar eclipse will be observed as a total solar eclipse (GMT).
GMT will be observed especially in the eastern part of Indonesia, while in other areas of Indonesia it will be observed as a partial solar eclipse. This solar eclipse will be observed as an annular solar eclipse in the southern Indian Ocean and Pacific Ocean.
At GMT 2023, the trajectory of the Moon’s core (umbra) shadow on the Earth’s surface will pass through parts of eastern Indonesia. Johan explained the duration of GMT at this point lasts 1 minute 16 seconds.
Most of the 2023 GMT trajectory passes through areas of the sea such as the Timor Sea and the Banda Sea. The land that the GMT route traverses is part of Timor Leste and several areas in West Papua.
Some of the areas that will be passed by GMT 2023 are Fak-fak Regency, Teluk Bintuni Regency, Teluk Wondama Regency, Yapen Islands Regency, and others. The forecast for the 2023 GMT sighting in Biak starts at 12.20 WIT, the peak of GMT occurs at 13.57 WIT, while in Jakarta the partial solar eclipse starts at 09.29 WIB and peaks at 10.45 WIB.
You can safely observe a solar eclipse using a telescope equipped with a solar filter, special glasses for solar eclipses, a telephoto lens DSLR camera equipped with a solar filter, and through a pinhole camera.
“Remember we can’t look at the sun directly without using a special filter for the sun,” he said.
Johan said the Solar Eclipse could be phenomenon interesting for researchers in Indonesia for research related to eclipses. Such as observing the sun’s corona, measuring the effect of gravitational lensing, the effect of a solar eclipse on ionospheric and atmospheric conditions, and the effect of a solar eclipse on the behavior of living things.
“GMT 2023 can also be an educational tool for Indonesian people, especially children, to learn science. In addition, a solar eclipse can attract many domestic and foreign tourists to visit tourist spots that offer the prospect of observing the eclipse,” said Johan.
