Twice Occurred In A Week, Giant Coronal Hole Torn The Surface Of The Sun

JAKARTA - For the second time in a week, a giant coronal hole about 20 times the Earth size is seen tearing the surface of the Sun.

NASA describes a coronal hole as the surface area of the Sun. These holes appear when a magnetic field, created by plasma, is fired directly into space.

Making it easy enough for the solar wind and some plasma to move across space at high speed. Such an area is less dense and cooler than the plasma that surrounds it. Therefore, they appear dark in the image of the sun.

From this second latest event, the coronal hole released a solar wind moving at a speed of 1.8 million mph to Earth. Of course this will have an impact in the form of a wind that is claimed to occur on Friday tomorrow.

According to NASA, it takes several days for the wind to reach Earth and sometimes triggers some aurora activity.

When compared to other newest coronal holes, this time is a relatively small category. However, it is feared that it will hit and damage satellites.

Such solar storms also have the power to disrupt GPS navigation and power grids. Currently, scientists are working to measure how severe the threat is and find ways to combat potential damage.

The National Oceanic and Atmospheric Administration (NOAA) has warned there will be little change for a larger radio outage between Wednesday and Friday this week, as quoted by The Sun, Thursday, March 30.

The discovery of a recent hole occurred just days (March 23) after a large hole that can load up to 30 Earths inside was seen.

As before, this week's coronal hole appeared near the solar equator. Its placement makes the emergence of fast solar winds. The wind can cause a period of geomagnetic storms at small and moderate levels.

But not long ago, NOAA said no small or larger geomagnetic storms would have occurred this weekend.
