    Double "Black Beam" Contrail Edge Shadow over Mt Shasta

    An unusual double edge shadow. Since the positioning of the contrails relative to the sun is important, it's rare to get two at once. Unfortunately only got some iPhone photos through the car windscreen. Later a large dark beam was pointing directly at Mt Shasta, which looked quite dramatic.

    "Black Beam" Contrail Shadow, Sunshine Coast, Australia

    I may of found my problem thinking in why I can't see that the beam I witnessed could have been a contrail shadow. I imagined the light from the sun as coming from the small sphere of the sun that I see. I can see by your drawing I am seeing it wrong. Okay I am getting closer to understanding...
