Abstract

The forbidden O I lines at λλ5577, 6300, and 6363 appear as faint absorption lines in the solar spectrum. Measurements of the equivalent widths indicate that the reversing layer has 7×10^20 oxygen atoms per square centimeter. Comparison with the equivalent widths of the infra-red permitted lines yields an excitation temperature of 5200° for oxygen. The possibility of using forbidden lines for determining the abundance of other light elements is discussed.
