Example:

Definition of symbols:

  • FORECAST of ionospheric and geomagnetic conditions

  • I I I I I = station indicator

  • DD = UT day of beginning of the 5-day period to which the forecast refers
  • JJ = UT day of the end of the 5-day period to which the forecast refers
  • m = last digit of month of year (1 = January, 2 = February . . . 0 = October, 1 = November)
  • HH = UT hour of message

  • ION / / = comes from IONospheric conditions

  • a a a a a = expected ionospheric conditions expressed by quality figures for corresponding date. The 6th quality figure refers to 31st day of a month.
    • 0 = quiet |Δ foF2| ≤ ± 20%
    • 1 = minor negative disturbance: 20% < |Δ foFs| < 25%
    • 2 = moderate negative disturbance: 25% < |Δ foF2| < 35%
    • 3 = major negative disturbance: |Δ foF2| > 35%
    • 4 = minor positive disturbance: 20% < |Δ foF2| < 25%
    • 5 = moderate positive disturbance: 25% < |Δ foF2| < 35%
    • 6 = major positive disturbance: |Δ foF2| > 35%

  • a / / / / = expected ionospheric conditions expressed by quality figure (see above) for the 31st day of a month, otherwise omit this group.

  • MAG / / = comes from MAGnetic conditions

  • b b b b b = expected geomagnetic conditions expressed by quality figures for corresponding date. The 6th quality figure refers to 31st day of a month (A-index for Moscow)
    • 0 = quiet (A < 15)
    • 1 = minor disturbance (15 <A < 25)
    • 2 = moderate disturbance (25 < A < 80)
    • 3 = major disturbance (A > 80)
