Good news for Indonesians especially those of you who like to observe celestial events! On Sunday (21/6), this equatorial region will be bypassed by an annual solar eclipse.
Previously, the Meteorology, Climatology and Geophysics Agency announced that we would get to watch the ring solar eclipse (GMC). But apparently the trajectory shifted, so the solar eclipse is partially what can be witnessed in Indonesia.
But take it easy, this event is still special. Because not all countries in the world can see it. Only countries in Central Africa, parts of Asia, Europe and Australia have the opportunity.
Well, if in Indonesia, which regions are given to see this eclipse? How do you watch it and what needs to be prepared? Check out the following explanation!
1. Actually the event that took place was a ring solar eclipse (GMC)
The annual solar eclipse in June occurs Sun, Moon and Earth are aligned in a straight line. But when that happens, the Moon is at its farthest point from Earth. Finally, not all the sun’s light can be covered.
The incomplete shadow of the Moon will leave a line of light that resembles a ring. That is why this phenomenon is referred to as a ring solar eclipse. Some people also refer to it as “ring of fire” because the Sun looks like a ring of fire.
Then why did Indonesia get a partial solar eclipse? The second point will explain it.
2. Why does Indonesia get partial solar eclipses?
BMKG states that there are two types of Moon shadows that are formed during GMC, namely the antumbra and the penumbra. Areas that are crossed by the Intumbra can see GMC. While those affected by penumbra will get a partial solar eclipse.
You can see the difference in the diagram above. If you look at the current position of the solar eclipse, Indonesia is located in the southern part of the antumbra or ring path. That is why this time we will witness a partial solar eclipse.
When this phenomenon occurs, part of the face of the Sun will be covered by the Moon. While some others remain bright as usual. The sun will look like a bitten cookie.
3. This is the territory of Indonesia that gets to witness an eclipse!
BMKG said that there were 432 cities and districts in 31 provinces that could witness this event. This means that not all regions of Indonesia have the opportunity.
The following is a list of regions that receive partial solar eclipses:
- Sumatra (Aceh, North Sumatra, West Sumatra, Riau, Bengkulu, Jambi, Riau Islands, South Sumatra, Lampung, Bangka Belitung Islands)
- Java (East Java, Central Java, West Java)
- Kalimantan (West Kalimantan, Central Kalimantan, South Kalimantan, East Kalimantan, North Kalimantan)
- West Nusa Tenggara and East Nusa Tenggara
- Sulawesi (West Sulawesi, South Sulawesi, Central Sulawesi, Southeast Sulawesi, Gorontalo, North Sulawesi)
- North Maluku and Maluku
- Papua and West Papua.

The time of the occurrence of a solar eclipse is indeed not the same in each region. It’s good for you to check via https://www.timeanddate.com/eclipse/solar/2020-june-21. After opening the site, type the name of the city or district in the search engine. You will get complete information from there.
5. What needs to be prepared to witness a partial solar eclipse?
Partial solar eclipses are events that are not difficult to observe. You can definitely watch it only by searching for the existence of the Sun.
But what you need to know is, you have to prepare several tools to see it. Among these are glasses with solar filter, telescope or binoculars with solar filter, or the easiest is a large basin filled with water. All this is necessary because we must not look directly at the eclipse without any protection.
6. Warning: it is strictly forbidden to see the sun directly!
It should be remembered and underlined that staring directly at a solar eclipse with the naked eye is very dangerous. Reporting from Space.com, the light will damage the eyes to cause vision problems called solar retinopathy.
What’s more, in a partial solar eclipse, there is an area of the Sun that still shines bright as usual. The human eye will not be able to capture light energy that is so large.
There are a number of do’s and dont’s that you must apply when you want to witness a solar eclipse. The following are:
- Use pinhole projector which can be made with perforated cardboard;
- See eclipse through reflection in water;
- Use binoculars or telescopes with solar filters;
- Don’t see the eclipse directly with the naked eye;
- Keep in mind that sunglasses won’t be able to protect your eyes;
- Don’t try to see it from a telescope or binoculars without a sun filter, this can cause blindness;
- Avoid looking at it from the reflection of the mirror.
Are you ready to watch this annual solar eclipse? Do not forget to prepare the things that have been mentioned to watch it safely, yes!
