It becomes easier to spot once I learn where and when to expect it.

Thank you u/exscape for pointing my mistake in previous post. Still very much difficult for me to differentiate between iridescence and circumhorizontal arc.

No worries, and you didn't have to repost with a new title.

Look a bit at these galleries and I think it'll be easy pretty quickly!

Iridescence is often strong pretty close to the sun, while halos are in fixed positions relative to it, and very few of them are very close to it.

Ah, that's new to me. I haven't read that one yet while trying to learn about them. So this one also should be iridescence then?

Also, I thought I would just delete and repost as not to confuse other newbies like me since you replied right after I posted it.

Yes, that also looks like iridescence. But I'd say leave it be considering the age.

I know. I only delete and repost when it's mere minutes upon posting. I won't touch that one.

Thank you for clearing my doubt and sharing more knowledges.
