Columns Format Description
==========================================================================================
1-6 I6 Geographic Co-Latitude in 0.001 degree.
The distance from 0° up to 180° from the North geographic pole.
A decimal point is implied betweem positions 3 and 4.
7-12 I6 East Geographic Longitude in 0.001 degree.
The distance from 0° up to 360° from Greenwich.
A decimal point is implied betweem positions 9 and 10.
13-14 I2 Year. Last 2 digits, 82 = 1982. See also column 26.
15-16 I2 Month (01-12).
17-18 I2 Day of month (01-31).
19 A1 Element (D,I,H,X,Y,Z,E or F).
20-21 I2 Hour of day (00-23).
22-24 A3 Observatory's IAGA 3-letter code.
25 I1 Arbitrary.
26 I1 Century digit:
Year = 2014, Century digit = 0,
Year = 1978, Century digit = 9,
Year = 1887, Century digit = 8
or blank.
27 A1 Preliminary or Definitive data.
Preliminary = P, Definitive = D.
28-34 9A1 Blanks.
35-394 60I6 60 6-digit 1-minute values for the given element for that
data hour.
The values are in nanoTeslas for the intensity elements H,X,Y,Z,E and F,
and in tenth-minutes for D and I (612 = l degree + 1.2 minutes East).
395-400 I6 Hourly mean value - the average of the proceeding 60 one-minute values.
401-402 Record end marker.
Two chars 'cr'= 13 and 'nl'= 10.
Each element value and the hourly mean is given in a 6-digit field including
a minus sign for negative values.
Missing data value spaces are padded with 999999.
The records are sorted according to observatory code, year, month, day, element.
