Russian cosmonaut Sergei Kud-Sverchkov talked about how the ISS flew through the aurora. This is what he is talking about wrote in your Telegram channel.
Let us recall that on January 20, a strong magnetic storm caused an aurora with red light. Since this phenomenon was observed at high altitude, it seemed to the ISS crew that the station would fly straight over it.
“We felt like we were literally floating inside this light. Although, of course, we only slightly covered the latitudes where the auroral oval is located. The glow was noticeable from the station, even as we flew over the Middle East!” he wrote.
In addition, the astronaut also said that the green light during the aurora is caused by oxygen atoms at an altitude of about 100 km. If the height increases to 300-400 the light will appear red.
“The higher, thinner layers of the atmosphere require more energy to produce light, so red is typically not as prevalent. Yesterday, with the worst storm in two decades, there was a lot of red light,” he added.
