Coronal magnetic fields.
Abstract
The observational evidence on the strength of the coronal magnetic field above active regions is reviewed. Recent advances in observations and plasma theory are used to determine which data are the more reliable and to revise some earlier estimates of field strength. The results from the different techniques are found to be in general agreement, and the relation 279-01, 1.02 ≲ R/R⊙ ≲ 10 is consistent with all the data to within a factor of about 3.
