โœฆ Synopsis


The spectrum of the S-component of solar radio emission has been investigated at 4 GHz, 17 GHz, 35 GHz, 70 GHz, and 94 GHz. The spectrum for a spot group which appeared late in March 1966 (McMath plage No. 8223), seems to be fiat at the frequencies above about 35 GHz. This implies that the emission is due to pure free-free emission at the frequencies above 35 GHz.

We have observed the slowly varying component of solar radio emission at a frequency of 34.5 MHz with half power beam widths of 26'/40' in the east-west and north-south directions, respectively. It is found that the observed brightness temperatures vary within the limits of 0.3x 106 K to 1.5 x 106 K
