of Romania took these on flights during his spells at the Las
Campanas and La Silla Observatories in Chile.
Air
journeys are an excellent way to see atmospheric optics

The lower view looks opposite the sun. Diffraction by
cloud droplets produces
a multiringed glory surrounding
the airplane shadow. Further out is a cloudbow (a
type of fogbow) showing
clear supernumeraries.
