Results are reported for observations of a quiescent limb prominence during a solar eclipse, which were conducted at a wavelength of 8 mm with a 22-m radio telescope. Part of the prominence was scanned as a filament projected against the solar disk. It is shown that the height of the radio prominence was the same as in the optical region, about 25,000 km, and its brightness temperature was 7000 K. Out-of-eclipse data indicate that the radio width of the filament may have been larger than the corresponding H-alpha width (1.5 arcmin vs 0.1 to 0.3 arcmin). It is noted that plasma flows toward the prominence were apparently detected in the radio range. The electron temperature of the prominence is estimated to be about 6500 K at the base and 8300 K at the top; the average electron density is estimated to be 5 billion per cu cm.
