WebThe ionosphere is also where the auroras occur when solar wind particles collide with oxygen and nitrogen atoms. The IRI transmits at frequencies between 2.7 and 10 MHz with a power of 3.6 megawatts. It transmits radio waves upward into the ionosphere, where they cause electrons to move in waves. Web1 okt. 2024 · In the terrestrial magnetosphere, the current system is formed at the night-side sector, and thus produces an auroral bulge at night. Due to the different energy sources between Saturn and the Earth, it is expected that their auroral current systems are fundamentally different, although the specific auroral driver at Saturn is poorly understood.
