(Stillness in the Storm Editor) The events spoken of in the following article have transpired. However, it is still a wealth of knowledge about how coronal holes and space weather affect human beings.
(Arjun Walia) Coronal holes on the Sun are constantly changing. They are caused by the Sun’s magnetic fields, which arch away from areas in the Sun’s corona that have become thin due to the lower levels of energy and gas. When these fields do not fall back, coronal holes appear.

As a result, the Sun emits enormous amounts of solar wind (radiation). Currently, one such hole is pointing toward Earth.
It is said that this radiation will be reaching Earth as early as the night of April 23rd and into April 24th and may cause interruptions in technology on Earth. This is not a rare event, however. A couple of years ago, NASA’s Solar Dynamic Observatory (SDO) observed a hole as wide as 50 Earths in the outermost layer of the Sun and its magnetic field.
This type of solar wind can produce some of the most beautiful auroras on Earth, cause geometric storms, influence Earth’s climate, and more. These ‘geometric’ storms, which we experience fairly regularly, can adversely affect infrastructures such as power grids, navigation systems, communication systems, and more. Theoretically, one day, a powerful blast of greater magnitude could completely wipe out all power on Earth…
