On Wednesday, April 8 and 9, 2015, a friend arrived from San Francisco, California. She took a lot of photos during the trip.
As soon as I saw the photos, I noticed an oval-shaped object in the sky. The object was in three different photos.
This was not visible to the naked eye during the photo shoot, she had no idea about the objects until they were visible in the photos afterwards.

Hypotheses
Re-reflections in lens lenses from a strong light source
The lens consists of a set of lenses (in some lenses - of mirrors), designed for mutual compensation of aberrations and assembled into a single system.
From the contour light (bright light sources behind the subject or next to it), caught in the frame or located outside the frame, parasitic reflections from the internal elements of the lens are formed, called glare (or in slang "hares").
Investigation
Based on the description of the eyewitnesses and the appearance and location of the objects in the photos (presented in the video) - this is the glare from the lantern.
