Abstract
The temperature of the solar corona is high, variable, and inhomogenous. As a result, the large scale temperature structure of the entire corona is poorly known. There are few, if any, full sun temperature maps of the solar corona in the literature. The soft x-ray telescope (SXT) on Yohkoh is able to provide useful temperature maps for regions where the x-ray signal is sufficiently strong. Previous SXT studies have shown that the coronal temperature decreases with height immediately over active regions (Klimchuk and Gary, 1995). Within coronal holes and beneath coronal streamers the mean temperature is observed to increase with height (Sturrock, Wheatland and Acton, 1996, Foley, Culhane and Acton, 1997). Here we present a full-sun temperature map to illustrate these and other features of the temperature structure of the corona.
