Ionospheric Disturbances
Ionospheric disturbances refer to the irregularities or variations in the ionosphere, which is the uppermost part of the Earth's atmosphere that is ionized by solar radiation. These disturbances can be caused by various factors such as solar flares, geomagnetic storms, and meteor showers. They can affect the propagation of radio waves and satellite signals, leading to communication disruptions and errors in navigation systems. Ionospheric disturbances can also impact the performance of spacecraft and their instruments, as well as pose a risk to astronauts. Therefore, understanding and predicting ionospheric disturbances is crucial for space and astronautical engineering.
