Description
Submillimeter observations made with a rapid-scanning interferometer
during the solar eclipse of June 30, 1973 are reported. Reduction,
correction, and plotting of the data is described, and the obtained
results show that the spike can be identified with emission from
chromospheric spicules. Models of spicules from optical wavelength data
indicate that the spicules are optically thick through the submillimeter
range. A more detailed analysis on the number density and length
distribution of the spicules above the photosphere, in the region near
the chromopause, is pending. It is noted that an examination of large
scale brightness distributions across the sun was prevented by time
limitations, and that submillimetric limb brightening still remains a
mystery.
