Astroimagers Chris Cross and David Colored-Beard, the latter currently using an experimental superheated steam-powered CCD camera, are reliably rumoured to have considered attempting to image the event, but at the point of publication any success by them has yet to be confirmed.
Asteroid GPS-WD40 was discovered during August 2005 during the Near Earth Asteroid survey conducted at Siding Spring Observatory by Gary Gordon and Rob McZero. Radar observations suggest that the asteroid is an irregular object about 5km by 2km and a high level of interest was shown by the international Astronomical community as to whether careful observation of the occultation could shed light on the size and nature of the mysterious SGP.
This latter object was discovered at the Cape of Good Hope by John Herschel during his famous southern hemisphere survey in the early part of the 19th century.
Herschel was not prepared to accept the existence of dark nebulae as conventional wisdom was that all nebulae were illuminated and that any dark areas were actually voids between the stars.
However, it has since been theorised by researchers at the Astronomy Department of the University of Burgerweldt that the rotation of the Earth creates vortices at the axis of rotation, that is, the North and South Galactic Poles, to which are channelled a quantity of the fine particles that normally make up the zodiacal light and the gegenschein.
The anomaly is that while such particles are seen by illumination when near the zenith, they do not apparently reflect light when at the North and South Polar Regions and it has been conjectured that the Earth's magnetic field in some subtle fashion gravitationally lenses near Earth lighting sources at the North and South Poles away from our line of sight.
It may well be that a similar effect may diminish the light of the occulting asteroid, and that, for example, Polaris is actually brighter than Sirius but dimmed by several magnitudes owing to it's proximity to the pole. Results of observations by other Astronomy centres are awaited with interest.
