| Zusammenfassung |
| A large set of limb CMEs has been used to determine the accurate relationship
between radial (V rad) and expansion (V exp) speeds of CMEs. It was demonstrated
that this relation is exceptionally well described by the function f(w)= 1/2 (1 + cot
(w)) representing a full cone model for the CME with a half width, w. We also
demonstrated that this relation for the halo CMEs could be very simple V rad = V exp. |
