Note: In July 1959 the records from Sacramento Peak, High Altitude and Hawaii Observatory were scaled side-by- side rather than separately and individually. Be¬ ginning with August 1959 the McMath-Hulbert Observa¬ tory records were scaled with the other three. By such intercomparison it is possible to discriminate between interference phenomena and small amplitude solar effects. It is also possible to report small events which on a single record might be overlooked.
