Abstract
A study has been made of an unusual meteor spectrum which contains only lines of neutral fron and a weak continuum. The absence of the D lines of sodium is particularly noteworthy and supports the meteoric, rather than atmospheric, origin for sodium in normal meteor spectra. The atmospheric velocity was only 13 km/sec. The orbit has a short period, small eccentricity, and low inclination to the ecliptic. The evidence indicates that the meteoroid must have been a nickel-iron fragment of asteroidal, rather than cometary, origin.
