The process of formation and disappearance of an ionospheric "hole"
in the F2 layer caused by the ejection of water molecules during
the flight of a space vehicle has been considered using the method
of computational experiment based on the mathematical ionospheric-magnetospheric 
model in a coordinate system fixed on the magnetic force line of the Earth.
