Marko Riikonen, Mika Sillanpää, Leena Virta, Daniel Sullivan, Jarmo Moilanen, Ismo Luukkonen. eso.org. November 20, 2000.

The authors compare reported Chilean halo observations with ice-crystal models. A model match supports their proposed interpretation, while direct atmospheric cubic-ice sampling remains missing. Acknowledged scholarly comments and weather-data assistance have incomplete contact records. The supplied paper does not establish an explanation for all UAP or current scientific consensus.
