✦ Synopsis
The brightness distribution of the equatorial region of the Sun has been investigated at 2.8 cm with an east-west resolution of 16.1", for the following days: 30 June, 1 July, 3 July and 4 July, 1972. The results confirm the existence of very intense cores inside active regions with typical sizes of the order of 10-30" and brightness temperatures in the range of l0 s K, with possible peaks up to 6 x 106 K. The relationship of these features to the Ha structure is also discussed.
