Abstract Logarithmic emission gradients and absolute integrated emission as functions of height are presented for moderately strong metal lines observed at the Khartoum eclipse by the High Altitude 0bservatory expedition. The gradients are controlled by the combined action of self-absorption and the chromospheric density gradient. Self-absorption is evaluated for a number of metal lines, from which follows an estimate of the density distribution through the low chromosphere The cores of many metallic Fraunhofer lines appear to originate in the chromosphere.
