Abstract : Observations of solar radio noise has been made at the Oslo Solar Observatory since 1954. Until 1962 the observing frequency was 200 Mc/s, but local interference then disturbed the measurements so heavily that a change of frequency was necessary. The measurements are now made on 225 Mc/s. The equipment is operated from February 1 to November 30 each year. The mid-winter shut down is due to the low solar altitude (less than 10 degrees at meridian passage); ground reflections then are disturbing. This report contains the observational data for the period 1960-64 and is a continuation of report no. 12, in which the data for 1958-59 were collected. The description of the method of tabulation of data, which introduces the tables, is much the same as in the previous report. It is followed by a discussion of the measurements which show how the data compare with those of some other observatories.
