I took this photo in Shijiazhuang, Hebei Province, China, 38°13'N 115°18'E (+38.23, +115.31) on the night of February 8, 2020. Here you can see a round object above the moon, and it was moving fast,the first photo was shot on 19:32:24, and the second was shot on 19:31:46. Can you please tell me what it was? Now that I have checked on SkyView Free, it seemed to be in the location of Pollux, but I don't think it was because it was big and it seemed like a planet which did not glow.
As in this question about an image of a partial solar eclipse, the object in question is:
- round and about half the apparent size of the Moon
- fainter and slightly bluish
- directly opposite the Moon relative to the center of the image
I believe it is a reflection of the Moon from coated surfaces in the camera lens.
