Another Elliptical Halo

Measurements of an elliptical lunar halo
Measurements of an elliptical lunar halo obvsered in the Indian Ocean.
June 6, 1992. Aboard the m.v. British Skill in the Indian Ocean.

"Between 1300 and 1345 UTC, a complete halo phenomenon was observed round the moon, as shown in the sketch. The ring was complete although its appearance was elliptical. Its horizontal diameter was 40 with its vertical diameter being 53.

"The illuminated part of the moon was not in the centre of the halo, its altitude at the lower limb (phase, new waxing) being 38 54'. The altitude of the upper part of the halo was 59 whereas the lower edge was at 6."

(Anderson, P.R.; "Elliptical Halo," Marine Observer, 63:65, 1993.)

Comment. Once again we have another observation called "impossible" by geophysicists. Halos, they say, must be symmetrical about the sun or moon. Yet, photos and precise measurements, like those above, demonstrate the reality of the phenomenon.

Science Frontiers Sourcebook Project Reviewed in:


  • "A sourcebook of unexplained phenomena is therefore a valuable addition to a collection of scientific literature. William R. Corliss has provided this in the past with his source books of scientific anomalies in several subjects, and now he has provided it for astronomy. He has done an excellent job of collecting and editing a large amount of material, taken in part from scientific journals and in part from scientific reporting in the popular or semi-scientific press." -- "The Mysterious Universe: A Handbook of Astronomical Anomalies", reviwed by Thomas Gold, Cornell University, in Icarus, vol.41, 1980

  • "An interesting, systematic presentation of unusual weather [..] This book is recommended for a general audience" --"Corliss, William R., Tornados, Dark Days, Anomalous Precipitation, and Related Weather Phenomena, Sourcebook Project, 1983.", revieweed in Choice, September 1983
  • "..the science is necessarily somewhat speculative, but Corliss's symthesis is based on reputable sources." -- "Corliss, William R. (Compiler). Lightning, Auroras, Nocturnal Lights, and Related Luminous Phenomena" reviwed by Joseph M. Moran, Univ. of Wisconsin in Science Books and Films, Sep/Oct 1983

  • "Before opening the book, I set certain standards that a volume which treads into dangerous grounds grounds like this must meet. The author scrupulously met, or even exceeded those standards. Each phenomenon is exhaustively documented, with references to scientific journals [..] and extensive quotations" -- "Book Review: The moon and planets: a catalog of astronomical anomalies", The Sourcebook Project, 1985., Corliss, W.
