“Amateur Astronomer Observes Hybrid Solar Eclipse on Indonesian Navy Ship”

TEMPO.CO, Jakarta – Astronomer amateur from the Jakarta Amateur Astronomy Association (HAAJ), Nurdin Nurdiansah, selected from among astronomers to make observations solar eclipse hybrid that passed through Indonesian territory on April 20, 2023 on a research ship belonging to the Indonesian Navy, KRI Spica-934.

For Nurdin, this hybrid solar eclipse observation completes his ‘collection’ of solar eclipse observations. “Yes, I have experienced four types of solar eclipses,” he wrote in a short message on Saturday, April 29, 2023.

He has made various observations, namely observing a partial solar eclipse in 2005, observing an annular solar eclipse in Anyer (Banten) in 2009, observing a total solar eclipse in Palu, Sigi and Donggala (Central Sulawesi) in 2016, observing an annular solar eclipse in Batam ( Riau Archipelago) in 2019, and observations of a hybrid solar eclipse in Kisar waters (Maluku) in 2023.

HAAJ and its parent company Planetarium and Observatory Jakarta spread several teams to observe this year’s hybrid solar eclipse. “There are two teams on the partial eclipse route (Jakarta and Anyer) and three teams on the main hybrid/total route, namely in Biak Papua, Kisar Maluku, Ihsan and Timor Leste,” he explained.

Observations onboard KRI Spica-934

Observation of the hybrid solar eclipse in the middle of the Banda Sea was carried out collaboratively between the Indonesian Navy’s Hydro-Oceanographic Center (Pushidrosal), the Boscha Observatory and Jalacitra-3 Expedition researchers.

The data obtained in this observation included documentation of the eclipse phase from the middle of the sea, meteorological data, oceanographic data, ecological acoustic data, and influence data on radio communication waves. These data will be further analyzed in the laboratory so that it is hoped that they will be useful for the advancement of maritime research and development in Indonesia.

The Commander of the Indonesian Navy’s Pushiros, Vice Admiral TNI Nurhidayat, directly monitored the observation of the hybrid solar eclipse by KRI Spica-934 in the middle of the Banda Sea. This is the first observation of a solar eclipse in the middle of the sea in Indonesia.

Nurhidayat hopes that KRI Spica 934 soldiers together with researchers can conduct research on the effect of a solar eclipse on ecological acoustics, marine mammals, and long-distance radio communications using High Frequency waves.

Danpushidrosal had the opportunity to communicate directly with the Boscha Observatory Team on Kisar Island and the KRI Spica-934 Commander in the Banda Sea in a live streaming of the hybrid solar eclipse.

Commander Pushidrosal said that direct observation of the solar eclipse in the middle of the sea would be concrete evidence for Indonesia’s young generation of theoretical physics in class and hoped to motivate them to pursue their aspirations as scientists who are beneficial to society, the nation, country and world.
