Olav Kjeldseth-Moe is emeritus professor of astrophysics at the Institute of Theoretical Astrophysics, University of Oslo. He is married to Else Wiestad, Ph.D. and Professor of Philosophy, University of Oslo.

Kjeldseth-Moe was born in 1940 in a small industrial community on the west coast of Norway. Since 1970 he has been involved in studying the Sun using space instruments. Educated in Oslo, he spent 6 years at the US Naval Research Laboratory (NRL).

At NRL Kjeldseth-Moe worked on calibrating NRL's spectrometer SO82B for Skylab. He took part in the operation of Skylab in 1973-74 as a science planner for NRL at JSC in Houston. Later he analyzed and interpreted Skylab observations in terms of physical conditions in the solar atmosphere. Returning to Oslo in 1977 he kept his contacts with NRL as a coinvestigator on the High Resolution Telescope and Spectrograph (HRTS) from its first flight in 1975. From 1986 to 2006 he was leading the Norwegian participation in the Coronal Diagnostic Spectrometer (CDS) on ESA's and NASA's SOHO satellite. The Norwegian contribution to CDS was the Quick Look Software and Electrical Ground Support Equipment.

The scientific interests of Professor Kjeldseth-Moe and his collaborators in Oslo have particularly covered dynamics and time variability of the solar corona. These were new aspects of the solar atmosphere, which were first revealed by SOHO. Presently his interest has shifted to the study of the Sun’s influence on Earth’s temperature.
