Description

Ultraviolet observations are, for cometary studies, especially important since the four basic atomic elements, H, O, C, and N have their strongest resonance transitions between 1200 and 1700 A. The most prominent features in all cometary spectra are the Lyman-alpha emission of atomic hydrogen at 1216 A, and the (0,0) band of OH near 3090 A. The intensity of these transitions is due to the large abundances of H and OH in cometary comae, (about 2 orders of magnitude larger than those of CN or C2), and their large g-factors of about 10-3 sec-1 at 1 AU. Recent spectroscopic ultraviolet observations of comets are presented, and the results derived from them are discussed. (Auth.)
