โœฆ Synopsis

If the Sun did not have a magnetic field, it would be as uninteresting a star as most astronomers believe it to be." attributed to ROBERT B. LEIGHTON "Magnetxc fields are to astrophysics what sex is to psychoanalysis." HENK VAN DE HULST (1988) Abstract. This review of stellar magnetm field measurements is both a critique of recent spectral diagnostic techniques and a summary of important trends now appearing in the data. I will discuss both the Zeeman broadening techniques that have evolved from Robinson's original approach and techniques based on circular and linear polarization data. I conclude ruth an ambitious agenda for developing self-consistent models of the magnetm atmospheres of active stars.

The observational difficulties of obtaining the magnetic field distribution in the chromosphere and corona of the Sun has led to methods of extending photospheric magnetic measurements into the solar atmosphere by mathematical procedures. A new approach to this problem presented here is that a const
