Solar an stellar coronae,earby stars. It is shown that a basic analogy exists between solar coronal physics and the phenomena observed in the coronae of other late-type stars. Recent X-ray observations of stellar coronae from EXOSAT are used to illustrate the main points.

Observations from space vs. ground based observations: Advantages and disadvantages,ve, either directly or indirectly, access to:.Instrumentation and observing modes have to comply with the scientific needs. With the aid of a few examples we discuss advantages and disadvantages of observations from space and from the ground.

Conference proceedings 1987 for the activity phenomena plays an important role in the contributions to this volume. For both students and researchers the general introduction by N. O. Weiss makes an excellent guide to this very active field of research. (See also Lecture Notes in Physics Vol. 291.)

Stellar activity and rotation,t role, still its correlation with various activity indicators has an essentially qualitative character, because other global stellar parameters undergo concurrent changes, making it difficult to isolate the pure effect of stellar rotation from observations.
