Amazing Novaya Zemlya sunset mirage and a mirage of Farallon Islands

This sunset started as a blank strip sunset https://aty.sdsu.edu/explain/simulati...
You could see miraged Farallon Islands on the left hand side of the sun.
However, the miraged images of the sun at first was not visible in one of the ducts. It is "Because rays that are trapped in a duct  cannot leave the Earth's atmosphere, an observer within the duct cannot see the Sun or other astronomical  objects in a zone of the sky, containing the ducted rays, that is centered on the astronomical horizon. Instead, this strip of sky is filled with miraged images of distant terrestrial  objects, if there are any in the duct." as Dr. Young explains https://aty.sdsu.edu/explain/simulati...
As Dr. Young explains “Because the duct was of finite length, the Sun eventually appears (seen through the far end of the duct)”. Such ducts are called leaky.
