Abstract

ACCURATE measurements of the wavelength dependence of interstellar obscuration in the spectral range from 10,000 Å to 3400 Å (refs. 1–4) show a distinct change in the slope of the extinction curve at 4300 Å. Extinction observations have been made for a number of galactic regions, and it is found that a change in slope always occurs at 4300 Å but that the magnitude of the change differs significantly from one region to another. At the same time, an unidentified interstellar band of half-width approximately 20 Å appears at 4430 Å, but the discontinuity in the slope of the extinction curve does not affect the profile of this band5.
