Galactic Radio

A survey of galactic radio-noise at 200 Mc/s, has been made for the region of the sky south of declination 45 �N. Results are expressed graphically in watts m.-2 (c/s.)-1 (steradian)-1, the maximum value being 20 x 10-21 W. m.-2 (c/s.)-1 (steradian)-1 at galactic latitude -3� and longitude 322�. Corrections have been made for the aerial beam width. No measurement has been made of the residual intensity from the coldest parts of the sky (the galactic poles) and this quantity, when known, should be added to the results quoted. The galactic noise provides a permanent and convenient standard for solar noise measurements, and its intensity for this purpose is evaluated.

Frequency Apparatus

The swept-frequency receiver is one of the most powerful tools for studying the processes that go on in the sun's atmosphere. However, the instrumentation becomes fairly elaborate if a large frequency range is to be covered by such an apparatus. Consequently, only a few such receivers have been built, and those that are in operation are somewhat limited in their frequency coverage. It then seems worth while to examine the data from existing fixed-frequency receiving stations in order to determine the extent to which they can supplement or approximate the results of the swept-frequency apparatus. Many solar observations at fixed frequencies have been made and are still being made by numerous observers. These data contain much meaningful information if they can be interpreted successfully.

Preliminary Description

The second Advanced Technology Satellite (ATS-II) carries a radio-astronomy experiment designed to perform radio-noise measurements in the range 0·5 to 3·0 MHz from above the terrestrial ionosphere. The spacecraft was launched into an 11000-km apogee, 180-km perigee orbit on April 6, 1967, and since there was considerable solar activity in the ensuing months it is possible to present a preliminary description of the kind of solar observations this experiment will provide.
