1) NORAD: NORAD number.
2) Date: YY-MM-DD (year-month-day)
^^^^^^^^^^^^^^^^^^^^^^^^^
3) Time: UTC of course.
4) Dir: Direction of satellite travel. Seems that N (north) or
S (south) are adequate but some far northern/southern observers may use
a different direction
5) aI: Azimuth of Iridium at max flare...measured eastward from north
6) eI: Elevation of max flare point..also called Altitude by some
7) aM: Azimuth of maximum elevation/altitude for this pass
8) eM: Maximum elevation/altitude
9) aS: Azimuth of the Sun at max flare.
10) eS: Elevation of sun at max flare
11) Phs: Sun phase angle. This is the Skymap convention:
Satellite-Observer-Sun. Quicksat users should subtract their value from
180.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
12) Dur: Duration of flare in seconds. Since it is subjective when to
start the timing, exact values are not critical.
13) Mag: Magnitude of max flare to whole magnitude is enough.
14) Obs: Observer initials. Now three spaces.
^^^^^^^^^^^^^^^^^
15) COSPAR: International designator.
