Saw this 4 years ago, still in awe

I saw this phenomenon on March 10, 2022 in NY’s Capital Region while out on an early morning walk. The progression what just stunning, it kept unfolding and evolving. I sent some pics to a local meteorologist hoping it would get on the news, but I didn’t even get a response. Please nerd out with me about this - what even is it btw??

Prism seen on wall!!

I couldn’t figure out what (besides the sun) was creating this, so I think it was the neighbor’s windows!! One was slightly open, thus my conclusion of one light then the second light’s reflection on the inside open part window’s reflection reflecting back…. Not sure if that’s what it was, but I searched for everything and anything, and that’s the only conclusion I could find!! It was beautiful, either way!!

Supernumerary rainbow?

Seen today around 6pm after a rainstorm! First I was stunned by the brightness of it, then by the double rainbow, and then by the strip of yellow running under the primary rainbow. Google suggested it was a supernumerary rainbow and I wanted to share with you all to get your sense and learn anything I can :)

One of the most amazing natural phenomena I have ever witnessed. Rhinelander WI, 2024. Last day of a nursing contract.

Faint rainbow streak and sun halo

Curious what the streak is, if it has a name.

Tangent Arc over Everett, Washington!

I've been photographing every halo, sun dog, or other atopic sightings here in the Seattle, WA area since Feb 2025 and this is my first time seeing an arc! I am very excited!!
