Solar Soft X-ray Burst Data


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

Time span: 1966-07-03 to 1967-07-26


This experimenter-supplied data set consists of data on solar soft X-ray (2- to 12-A) flares and parameters describing them. The data are on one BCD magnetic tape. The data for each flare include: date, start time (UT), time(s) of peak(s), end time, flux increase above background (at burst maximum), ratio of total flux to background (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. These are analyzed data and are complete.
