1- 2 I2 Data code; always 31.
3- 5 I3 Station code, 777 for GOES
6- 7 I2 Year
8- 9 I2 Month
10-11 I2 Day
12-13 A2 Asterisks mark record with unconfirmed change.
14-17 I4 Start time.
NOTE: If event is correlated to an optical
flare in data prior to 1997, the event times
are for the optical event. For data after 1996,
these event times WILL BE FOR THE XRAY EVENT ONLY.
18 1X
19-22 I4 End time.
23 1X
24-27 I4 Max time.
28 1X
29 A1 N or S for north or south latitude of correlated
optical flare, if known.
30-31 I2 Latitude of correlated optical flare, if known.
32 A1 E or W for east or west central meridian distance
of correlated optical flare, if known.
33-34 I2 Central meridian distance of correlated optical
flare, if known.
35 A1 Optical importance based on flare area = S,1,2 or 3.
36 A1 Optical brightness: F=faint, N=normal, B=bright.
37-59 33X
60 A1 X-ray class: C,M,X code the maximum power of 10
the 1-8 Angstrom flux attains.*
61-63 F3.1 X-ray intensity: a number from 1.0 to 9.9 that
multiplies the X-ray class.
64-67 I4 Calcium plage region in which flare occurred.
68-71 A4 Station name abbreviation - GOES.
72 1X
73-80 A8 Remarks: Beginning with January 1997 data,
the integrated flux from event start to end
will appear here if available (units = J/m*2).
81-85 I5 NOAA/USAF sunspot region number.
86 A1 Blank; may be used to add a letter to a region.
87-88 I2 Central meridian passage year.
89-90 I2 Central meridian passage month.
91-94 F4.1 Central meridian passage day.
95-100 A6 Blank

* X-ray classes are classified according to the order of magnitude
of the peak burst intensity (I) measured at the Earth by satellites
in the 0.1 to 0.8 nm band as follows:

Class W/m*2 Ergs/cm*2/s
B I < 10E-6 I < 10E-3
C 10E-6 <= I < 10E-5 10E-3 <= I < 10E-2
M 10E-5 <= I < 10E-4 10E-2 <= I < 10E-1
X I >=10E-4 I >=10E-1
