New observations of the solar ultraviolet chromosphere.We present some of the results of a rocket flight which obtained a stigmatic spectrum of the sun in the region 1190 to 1320A. The experiment achieved a spectral resolution of 0.01A throughout this range, and the effective angular resolution was about 20 sec. Lines which are formed in the chromosphere and transition zone show strong fluctuations with position on the disk. The correspondence between the H Lyman-alpha profile and chromospheric details seen in the Ca K-line is demonstrated.
