The Impact of the Solar Storm on the Territory of Indonesia

Jakarta

The National Research and Innovation Agency (BRIN) provided an explanation of the solar storm that could have an impact on Indonesia. BRIN said that Indonesia did not get as severe an impact as areas at high latitudes such as around the Earth’s poles.

Quoted from detikInetBRIN Space Center researcher Johan Muhammad explained that Indonesia would not experience such a severe impact when a solar storm occurs. That’s because Indonesia is located on the equator.

However, this does not mean that Indonesia is free from the effects of the solar storm. Space weather will have a lot of impact on interference with high frequency radio signals (HF) and satellite-based navigation.



“In Indonesia, space weather due to solar activity can interfere with communication between HF radio users and reduce the accuracy of satellite-based navigational positioning, such as GPS,” he said as reported by Antara. detikJabarSunday (14/8/2022).

In addition, due to the increasing dependence of people in Indonesia on satellite technology and global economic networks, disturbances to satellites and electricity networks in high latitude areas such as the poles due to space weather can of course also affect human life in Indonesia indirectly.

He continued, when a solar storm occurs, we often feel excessively worried and the rumors that are scattered often associate this with the apocalypse. Responding to the term solar storm apocalypse, Johan called it a wrong term and needed to be corrected.

“There is no such term in the scientific community. We have lived side by side with space weather for a long time. Solar activity occurs regularly. What we need to understand is how it works and mitigate its negative impacts as best we can,” he said.

Johan continued that BRIN also provides education to the public so that they do not panic and are not easily swayed by the circulating hoaxes related to the solar storm.

“The sun has a cycle of about once every 11 years. This cycle is not always the same at all times. Sometimes, the sun is very active releasing explosive energy, while in other periods the sun is very calm,” explained Johan.

This 11-year cycle has been known for a long time by humans. At least, the existence of the solar cycle has been well documented since the 18th century. Currently, we are at the beginning of the 25th cycle which is expected to reach its peak in 2024-2025.

At that time, solar activity is expected to increase with the frequency of flares and coronal mass ejections likely to increase.

Solar activity has often occurred in the past and is still ongoing today. We must understand the processes and impacts of these various solar activities and anticipate their negative impacts as best we can.

“Space weather is a condition in the space environment, especially between the Sun and Earth, which includes the condition of the Sun, the interplanetary medium, the Earth’s upper atmosphere (ionosphere), and the Earth’s magnetic envelope (magnetosphere). Like the weather on Earth, space weather is dynamic and very depends on the activity of the sun,” he said.

Johan explained that the Sun as the main energy source in the Solar System, has an influence on space weather. The sun regularly releases energy in the form of radiation.

Several solar activities that have a major influence on space weather conditions include flares, coronal mass ejections, and solar winds.

“Solar activity directly changes the density and pressure of plasma in the interplanetary medium and the ionosphere, and increases the magnetic pressure on Earth’s magnetosphere. As a result, various electromagnetic wave signals commonly used by humans for communication and navigation purposes can be disrupted during extreme solar activity,” said John.
