Predicated on the assumption that the Croydon Antarctic/Eclipse flight would be over the coastal region near Casey (appx longitude = 110E, 66.5S) prior to ascending to high altitude (appx. 40,000 ft.) for the eclipse run, I have looked at number of possible flight intercepts.

For background information on Eclipse Flight calculations see: EFLIGHT Software Description.

Table 1 gives the instantaneous circumstances of the 23 November 2003 total solar eclipse as viewed from an altitude of 40,000 ft. from an aircraft moving with a ground speed of 470 nM/hr on a heading to keep the Sun directly out the port (sun) side windows at mid-eclipse.  This table also compares the static duration (i.e., what would be seen by a non-moving observer) to that achieved from such a moving platform.

Static = Duration of totality as seen by non-moving observer
Moving = Duration of Totality as seen by Observer on flight path considered
W km = projected shadow width in km
ALTd = Altitude of the Sun at mid-eclipse in degrees
AZIMd = Azimuth of the Sun at mid-eclipse in degrees
ECC = eccentricity of projected the shadow ellipse at mid eclipse

The duration of the eclipse is maximized at ~ 22:49UT, with the Sun 15.2 degrees above the horizon.  This would require flying appx. 1050 km (570 nM) over inland terrain to a longitude of appx. 72.7S to the point of mid-eclipse intercept.  A small loss in the achievable duration of totality (3.6 seconds, or -2.6% of achievable) would be incurred by flying to a point on the coast, at a U.T. intercept of 22:40 U.T. which nearly minimizes the flying distance from Casey (~715km, or 390nM).  It is instructive to look at a schematic map which illustrated this:

A "totality run" from eight minutes before and three minutes after mid-eclipse a 22:40 UT mid-eclipse intercept (at 40,000 ft. with the Sun orthogonal to the direction of flight at mid-eclipse) may be characterized by the table below which gives:

HH:MM:SS =         Universal Time (Hours, Minutes, Seconds)
UM Lat, UM, Long = Coordinates of the center of the lunar umbral shadow
Width =            Width of the lunar umbral shadow projected on the geoid at flight altitude
SunAz, SunAlt =    Altitude and Azimuth of the Sun
AC Lat, AC Lon =   Coordinates of the Aircraft (waypoints) required for the central intercept
Mid-deltaT =       Time in seconds from mid-eclipse
Mid-deltaD =       Distance of Aircraft from mid-eclipse intercept)
LOS = Line-of-sight deviation angle to sun from window orthogonal
