No, as I can see flares on Apollo without any strong light source.

they can take other shapes similar to the one appearing in NASA's .

Yep, a very nice one, and definitely not a halo as to get one that size you would need actual fog which there is no sign of in the pic.

Note how it includes a reflection of the fiducial screen off one of the lens elements.

lens elements is something and lens flare is something else.
laughable. As if there was a visible fog in the street lamp.

Lionking, are you deliberately acting stupid to annoy us? Every time you point a camera at a bright light you will get some sort of lens flare due to internal reflection inside the camera. This applies whether in an atmosphere or not, because it is something that happens in the camera, not outside it. Halos are atmospheric phenomena, and to get a good photograph of one, you usually have to block out the sun itself to avoid lens flare which would swamp the halo. Check out the other halo photographs on the site I linked to: www.sundog.clara.co.uk/halo/circular.htmand notice the use made of chimneys, street lights, etc.

Lens flare due to the sun, which is just out of frame. A lens flare does not have to include the light source, but can be a series of reflections of it in a line.

so , how do you tell a halo from a flare?

how do you know the sun halo in your site is not a flare? For a start, it's behind the chimney. Also, it has the right diameter for that type of halo.

Lens flare is visible in front of objects, as it is an artefact caused internally in the lens assembly. Can you find any examples of Apollo photos where the flare is blocked by physical objects in the photograph? I've never seen any.

not yet. the fact that NASA blackened the sky makes it more difficult. If you can present me with that individual photo with the speck of light that Ian fraser was unmasking, maybe we can look better into it. I couldn't yet find the photo with that speck of light with the series the composite was made of.
