✦ Synopsis
In order to avoid the disagreements and difficulties now found in the interpretation of quiet-Sun UV observations concerning the chromosphere-corona transition region, 6-and ll-cm maps obtained at cycle maximum with the Nanqay radiotelescope are used in combination with existing measurements of the central brightness temperatures at centimetric wavelengths and with the hydrodynamic conservation equations so as to obtain an equatorial, quiet solar atmosphere model between 10000 K and 300000 K, in the interspicular regions. This model introduces a large ascending velocity in these regions. Some of the consequences of the model concerning the heating and replenishment of the corona are discussed. An explanation of sudden disappearance of quiescent prominences is suggested.
