Abstract
Photographs of the Sun in predominantly Lα radiation (centered at 1215.67 Å) with 3″ spatial resolution were taken from an Aerobee rocket shortly after fourth contact by the Moon on the eclipse day of 1972 July 10. This preliminary reporting of the results describes the instrument and shows two of the photographs taken. The supergranulation is manifest and active regions and filaments are well resolved over the entire disk. Densitometer traces across the disk are presented giving the flux incident on the Earth from active regions, cell boundaries, and filaments.
