In July 1963, the U. S. Naval Research Laboratory flew an Aerobee rocket equipped with a Bragg Crystal Spectrometer in an attempt to record an x-ray spectrum of solar emission. A pointing control was used to keep the device accurately pointed at the Sun. A spectrum of about 12 lines between 12 and 25 Å was recorded, made up mainly of lines from O VII, O VIII, N VII and Fe X VII. The O VII and N VII lines appeared to come from the entire solar disk. The Fe XVII lines originated almost entirely in a single plage region.

Le N. R. L. a tenté en juillet 1963 d'obtenir un spectre de l'émission X du Soleil avec une fusée Aerobee équipée d'un spectromètre à cristal de Bragg. L'engin comportait un dispositif de pointage automatique sur le Soleil. On a enregistré environ 12 raies entre 12 et 25 Å, principalement dues à О VII, О VIII, Ν VII et Fe Χ VII. Alors que les raies de О VII et Ν VII semblent émises par le disque en son entier, les raies de Fe XVII sont produites presque uniquement par une seule région active.

Резюме

Η. И. Л. попыталась в иоле 1963 г получить спектр излучения X солнца с ракетой Aerobee снабженной кристаллическим спектрометром Брагга. Снаряд содержал устройство автоматической наводки на солнце. Было зарегистрировано около 12 линий между 12 и 25 Å, происходящих главным образом от О VII, О VIII, Ν VII, и Fe XVII. В то время как линии О VII и Ν VII по-видимому излучены всем диском, линии Fe XVII произведены почти только одной активной областью.
