|4-5||I2||YEAR (last 2 digits, 82 = 1982)|
|9-10||I2||DAY OF MONTH (01-31)|
|15||A1||INTERNATIONAL QUIET or DISTURBED DAYS, Q=1,D=2|
|16||I1||Blank for data since 1900,8 for data before|
|17-20||I4||Tabular base, in degrees for D and I,
hundreds of nanoTeslas (gammas) for the intensity elements.
The bases are right adjusted and signed if negative.
Negative values are identified with a minus sign
either adjacent to the first significant digit or in the high-order
position of the field (position 17).|
NOTE: A blank digit will not appear between a (-) sign and the first significant digit. For example, a base may appear as -050 or b-50 but not as -b50(b=blank).
|21-116||24I4||Twenty-four 4-digit Hourly Values for the day. The values are in tenth-minutes for D and in nanoTeslas (gammas) for the intensity elements. The first hourly value represents the mean value between 00:00 UT and 01:00 UT, ..., the 24th value represents the mean between 23:00 UT and 24:00 UT. Rules for negative values are the same as those described for tabular bases. A missing value is identified by 9999.|
|117-120||I4||Daily Mean. Rules for negative values are the same as those described for tabular bases. If any of the hourly mean values for the day are missing 9999 will appear as the daily mean.|
