The Sun and the Earth - composition

This image shows an approximative comparison between the Earth and the Sun. The Sun is about 109 times the size of the Earth.

 

This rough comparison shows the size of an eruption on March 7, 2023.

 

The solar eruption took place in the northern hemisphere of the Sun at around 40 degrees.

 

In this image, the northern hemisphere is up and the southern hemisphere is down.

 

Image cropping - this image is in false colors. SDO give a red filter to AIA304 filter.

 

Observed by SDO on March 7, 2023 at a wavelength of 304 A.

 

The wavelength of the sun is ultraviolet, allowing us to observe helium losing two electrons.

 

The temperature oscillates between 40,000 and 60,000 degrees.
