JAKARTA (Antara) – Indonesia has a low risk of being affected by solar storms or activities, said researcher Johan Muhammad of the National Research and Innovation Agency’s (BRIN) Research and Space Center.
In Indonesia itself, the effect achieved (solar activity, ed.) is not as large as at high latitudes such as the regions around the Earth’s poles. This is because Indonesia is located on the equator, he told reporters in Nation World News on Friday.
Solar activity directly changes the density and pressure of plasma in the interplanetary medium and ionosphere, and increases the magnetic pressure in Earth’s magnetosphere.
This causes various electromagnetic wave signals that are commonly used by humans for communication and navigation purposes to be disrupted during extreme solar activity.
In addition, the Sun, as the main energy source in the Solar System, has an effect on space weather.
The Sun regularly releases energy in the form of radiation. Many solar activities that have a major impact on space weather conditions include flares, coronal mass ejections, and solar winds.
Space weather will have a huge impact on high-frequency radio signals (HF) and interference with satellite-based navigation.
In Indonesia, space weather due to solar activity can disrupt communication between HF radio users and reduce the accuracy of satellite-based navigational positions, such as the Global Positioning System (GPS).
He pointed out that due to the increasing dependence of people in Indonesia on satellite technology and the global economic network, disturbances to satellites and power networks in high latitude regions such as the poles due to space weather can also indirectly affect human life in Indonesia.
Space weather is a condition in the space environment, specifically between the Sun and Earth, that includes the positions of the Sun, the interplanetary medium, Earth’s upper atmosphere (ionosphere), and Earth’s magnetic envelope (magnetosphere).
He said that like the weather on Earth, space weather is dynamic and highly dependent on solar activity.
Johann explained that there is no such thing as a solar storm apocalypse among the scientific community.
We have been living side by side with space weather for a long time. There is regular solar activity. He said that we need to understand how the process goes and minimize the negative impacts as much as possible.
He appealed to the public not to panic and not to be easily misled by the rumours related to the solar storm.
The cycle of the Sun occurs approximately once in 11 years. Currently, it is in the beginning of its 25th cycle which is expected to peak in 2024-2025.
At its peak, solar activity is expected to increase with the frequency of flares and coronal mass ejections likely to increase.
