X-Ray (2 to 8 A) and UV (1050 to 1350 A) Data


Availability: At NSSDC, Ready for Offline Distribution (or Staging if Digital)

Time span: 1960-06-22 to 1960-11-01


This data set is in a published report in the Journal of Geophysical Research, v. 67, pp. 2231-2253, June 1962. The report, written by the principal investigator, consists of 23 pages, 14 of which contain some type of reduced or analyzed X-ray and Lyman-alpha flux data. Included are six pages of time-ordered, reduced X-ray fluxes, in tabulated form, accompanied by data on all reported flares and other associated solar events. Approximately 100 events (17% of the total number of readable satellite records obtained between June 22, 1960, and November 1, 1960, during periods when the solar aspect angle was less than 30 deg) are listed. Only those readings that had measurable fluxes are included. There are also three pages of graphs depicting the spin precession history of the SOLRAD 1 satellite, four pages of graphs showing various kinds of analyzed data, and one page giving a summary of the major events observed. In addition, there are graphs depicting the spectral sensitivity of the Lyman-alpha photometer, the X-ray photometer's spectral response characteristic, the angular response of the X-ray photometer, and 1 day of raw telemetry data from the Lyman-alpha and X-ray detectors. The quality of the data is good.
