    Cols   1- 15: Object number and international designation.
    
    Cols  17- 20: Four digit station number.
    
    Col       22: Station status code.
    
    	      Sky condition codes:
    
    	      E = excellent: no Moon/clouds, great seeing, minimal air/light pollution
    	      G = good     : no Moon/clouds, conditions could be better, but not much
    	      F = fair     : young/old Moon, some air/light pollution making fainter stars invisible
    	      P = poor     : gibbous Moon, haze, more air/light pollution making more stars invisible
    	      B = bad      : bright Moon, air/light pollution, some clouds; difficult
    	      T = terrible : bright Moon, air/light pollution, looking through clouds
    
    	      Station status codes:
    
    	      C = clouded out
    	      O = sky clear, but observer not available
    
    	      The purpose of the 'C' and 'O' codes is to enable reporting of
    	      "station unavailable" status to a network coordinator.
    
    Cols  24- 31: UTC date. Four digit year, two digit month and day of month.
    
    Cols  32- 40: UTC time. Two digit hour and minute. Seconds are reportable to
    	      a precision of 0.001 second (same as TLE precision). If
    	      significant digits are not available for columns 36, 37, 38,
    	      the unused columns should be blank or zero. Time uncertainty
    	      is specified in the next field.
    
    Cols  42- 43: Time uncertainty. Expressed as MX, where M = mantissa, and X =
    	      exponent input. Evaluated as M*10E(X-8). Examples:
    
    			     MX = 15: 1*10E(5-8) =   0.001 sec
    			     MX = 56: 5*10E(6-8) =   0.05  sec

    Col       45: Angle format code. BLANK IF NO POSITION IS REPORTED.
    	      To allow for user preference, four RA/DEC and three AZ/EL
    	      formats are provided. The first six of these are the same
    	      formats as used in the OTWG system, with the exception that
    	      one less digit of precision is available in both position
    	      coordinates. Positional coordinates are reported in columns
    	      48-61. The positional uncertainty is reported in columns 63-64.
    	      The seven positional formats are:
    
    				     50        60
    				    89 123456789 1234
    
    		 Format 1: RA/DEC = HHMMSSs+DDMMSS MX   (MX in seconds of arc)
    			2: RA/DEC = HHMMmmm+DDMMmm MX   (MX in minutes of arc)
    			3: RA/DEC = HHMMmmm+DDdddd MX   (MX in degrees of arc)
    			4: AZ/EL  = DDDMMSS+DDMMSS MX   (MX in seconds of arc)

    Cols  56- 61: Observed DEC or EL
    
    Cols  63- 64: Positional uncertainty. Expressed as MX, where M = mantissa,
    	      and X = exponent input. Evaluated as M*10E(X-8). Given in seconds,
    	      minutes, or degrees of arc according to the format used. Assumed
    	      to apply equally to both components.

    Col       66: Optical behavior code. BLANK IF NO DATA.
    
    	      Optical Tracking Working Group Codes:
    
    	      E = unusually faint because of eclipse exit/entrance
    	      F = constant flash period
    	      I = irregular
    	      R = regular variations
    	      S = steady
    	      X = irregular flash period
    
    	      Flash Period Codes:
    
    	      B = time zero for averaging several flash cycles
    	      H = one flash in a series
    	      P = end time for averaging several flash cycles. Time interval
    		  from last "B" report divided by flash period reported on
    		  this line gives number of flashes that occurred since "B".
    
    	      Miscellaneous Visibility Codes:
    
    	      A = became visible (was invisible); use E for eclipse exit
    	      D = object in field of view, but not visible
    	      M = brightest
    	      N = faintest
    	      V = best seen using averted vision

    Cols  72- 73: Magnitude uncertainty. Implied decimal point
    	      between cols 72 and 73. BLANK IF NO DATA.
    
    Cols  75- 80: Flash period in seconds. Implied decimal point
