USXRA Codes

Solar x-ray events..

Example:

Definition of symbols:

  • USXRA comes from Solar X-RAy events

  • I I I I I = station indicator

  • Y = last digit of year
  • MM = month of year, 01 = January, 02 = February, etc
  • . DD = UT day of month

  • SS = satellite
    • 06 = GOES-6
    • 07 = GOES-7
    • 08 = GOES-8
    • 09 = GOES-9
  • E = energy range
    • 1 = .1-.8 nm
  • NN = number of events

    • 0 = indicates that the begin time of the event follows
  • HHmm = UT hour and minute of beginning of event

    • 0 = indicates that the maximum time of the event follows
  • HHmm = UT hour and minute of maximum for event

    • 0 = indicates that the the end time of the event follows
  • HHmm = UT hour and minute of end time of event

  • Maximum Flux:
  • Q = qualifier
    • 0 = uncertain data
    • 1 = certain data
  • ab = x-ray flux in Wm-1 where ab = a.b
  • S = sign of the exponent to apply to a.b
    • 0 = positive
    • 1 = negative
  • p = power of ten to apply to a.b

Note: abSp reported as 4192 would equal 4.1 x 10-1Wm-1

Note: / is to be used for data not available.

  • Integrated flux (start thru end):
  • 9 = qualifier
  • ab x-ray integrated flux in Jm-1 where ab = a.b
  • S = sign of the exponent to apply to a.b
    • 0 = positive
    • 1 = negative
  • p = power of ten to apply to a.b

Note: abSp reported as 5692 would equal 5.6 x 10-1Wm-1

Note: / is to be used for data not available.
