What Is Aurora?

We meet again, here to discuss interesting things that happened on our beloved earth. By the way, how is the weather in your area? Hot, cloudy, or rainy? Summer, rainy season, spring, autumn, winter, or is it durian season? As we know Indonesia is traversed by the equator, so it only consists of two seasons, namely the rainy season and the dry season. Have you ever experienced winter? What is the atmosphere like in the polar regions, which are mostly covered by ice? The polar region does have its own charm with a wide expanse of thick snow.

On this occasion, we will discuss one of the phenomena in the polar regions and surrounding areas. This phenomenon is known as the Aurora, which is a colorful sky phenomenon with a beautiful blend. The charm of the beauty of the sky that is presented is very pleasing to the eye and is able to hypnotize many people. The sparkling Aurora color sweep looks even more beautiful when combined with the dark night sky.

What is Aurora?

Aurora is a light that shines in the sky at night. The Aurora phenomenon will not be the same from one place to another because there are influencing factors, such as location, pollution levels, weather, and others. The resulting glow will be more clearly visible the closer you get to the poles. The resulting form is different even at the same time and place.

The process of the occurrence of the Aurora

Caused by the sun releasing the solar wind that is formed from sunspots or sunspots. Sunspots can be formed due to convection flows from the high center of the sun, causing the darker and cooler parts to appear. In the dark area, the temperature increases, and the pressure will continue to occur so that the sunspot forms flares or flames. These flames, then release charged particles known as the solar wind.

When a solar storm occurs, the energy and tiny charged particles interact with the Earth’s atmosphere. Then the particle moves closer to the magnetic center in the north and south pole regions. There is an interaction in the form of excitation-relaxation of the electrons to produce a beautiful colorful glow called the Aurora.

Types of Aurora

Aurora is divided into two, namely Aurora Borealis and Aurora Australis. The Aurora Borealis has another name for the Northern Lights because it is located at the north pole. The resulting light displays many colors, there are red, green, blue, yellow, and even pink. The shapes also vary, ranging from beautiful faces, monsters, bows, and others. The Aurora Borealis will be visible in the Northern Hemisphere. There are several ideal places to see the Aurora Borealis or the Northern Lights, you know. These countries are Norway (Svalbard), Sweden (Jukkaswarvi), Finland (Kakkslauttanen), Northern Canada, and America (Alaska).

In the south polar region, there is also the Aurora Australis or the so-called Southern Lights. As with the Aurora Borealis, the appearance of the Aurora Australis is difficult to predict. We must be smart to look for opportunities and choose the best place to gaze at the beauty of this celestial phenomenon. The Aurora Australis can be seen in New Zealand, Australia (Tasmania), Antarctica, South Georgia Island, the Falkland Islands, and Argentina. You can look for opportunities in May-September because Aurora appears more often

Well, those are some interesting facts about Aurora whose beauty can spoil our eyes. For those of you who are interested in hunting, Aurora, make sure not to travel alone and prepare supplies because their appearance is uncertain.
