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)
