Sounds Of The Sun

Below are some dramatic images of the Sun’s Coronal Holes for the year 2018.

Although the Sun is usually peaceful during its Solar Minima phase, it hasn’t been quite active during 2018 forming imense coronal holes. It has spouted a few X-class flares, and in 2018 it has not been all peace-and-quiet. In fact, it has been very active as far as forming active coronal holes, which has increased solar wind activity, generating active even Kp6 Geomagnetic storms.

The Kp Geomagnetic Storm-scale is solar storm measurement obtained by calculating the mean of geomagnetic activity observation data obtained at 13 geomagnetic observatories around the Earth. These observations are completed within a 3-hour-range.

The index Kp is the mean of these data calculations. And it is a standardized measurement. Obviously, it reflects the measurement of geomagnetic storms caused by solar activity such as solar flares, filaments and other strong solar activities which emit high radiation charged solar winds towards Earth.

The 13 geomagnetic observatories are located between 44 degrees and 60 degrees northern or southern of the geomagnetic latitude of the Earth and are manned by scientists who study the effects of the Sun on Earth.

Below are some images of the Sun Coronal holes since November of 2018.
