Listings of Solar Soft X-ray Burst Data on Microfilm


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

Time span: 1967-07-26 to 1969-08-13


This data set consists of a listing of solar soft X-ray (2- to 12-A) flare data on 35-mm microfilm. The listing includes, for each flare: date, start time (UT), time(s) of peak(s), end time, flux increase above background (at burst maximum), ratio of total flux to background flux (at burst maximum), integral of flux increase above background for the burst duration, flags indicating either breaks in the data stream or the number of peaks, and ratio of time lost because of data gaps to the total burst time. This data set is a printout of data set 67-070A-01D. Data from IMP-D (data set 66-058A-05E) are also contained on this reel of microfilm.
