The multiple absorption components in the Balmer lines of P Cygni indicate that shells are ejected regularly with a period of about 200 days. The newly found multiple, flat-topped emission components are attributed to thin, spherical, expanding shells. Together with the absorptions they allow the derivation of a velocity law, illustrated in the following by a sequence of figures.
