✦ Synopsis

One and two-dimensional observations were made at 1.64 tt, the deepest observable level in the solar atmosphere; at 1.72/1, representing the chromosphere; and at 1.17/~, representing the visible photosphere. Structures distributed on a supergranular size scale (30000 kin) are apparently present at all levels. These structures in the deep photospheric level (1.64 ,u) seem to be a 50K-500K temperature decrease over surrounding photosphere confined to the magnetic field elements with horizontal scales less than 4000 km at supergranular boundaries, rather than a general temperature structure over the entire supergranule cell appropriate to convective energy transport.
