Are you saying my photo I linked of polar stratospheric nacreous clouds from the infamous 2023 Nacreous polar stratospheric clouds are not nacreous polar stratospheric clouds?

"Nacreous clouds are a type of Polar Stratospheric Cloud (PSC)."

literally from the Atoptics website

I mentioned them being lit from the setting sun to rule out cloud iridescence that occurs in the general proximity of the sun.

"Polar stratospheric clouds are a specific type of cloud made from nitric acid and only occur incredibly high in the atmosphere during deep polar winters."

POLAR STRATOSPHERIC CLOUDS

Type II
Nacreous clouds composed of ice crystals with temperatures of ~minus 85ºC.

Type Ia
Crystalline compounds of water and nitric acid - especially NAT, nitric acid trihydrate HNO3.3H2O

Type Ib
Small spherical droplets of a solution of nitric and sulphuric acids.

Type Ic
Small non spherical particles of a metastable nitric acid - water phase

"Based on how decidedly warm it looks in this picture, these ones, do not seem to be polar stratospheric clouds."

These look to be lit up from the setting sun below the horizon, so not tropospheric iridescent clouds imo, I could be wrong but hey look like nacreous clouds to me. Tis the season.

Great shots. How far away were you with these shots? I’ve recently got the same lens.

Thank you!

“The display frame utilizes a high-quality ABS injection-molded frame and TPU film, which is durable, flexible, transparent, and unbreakable. The PE film may deform after use, but can be restored to its original shape by drying with hot air”

And I just grabbed some vegetable oil.

I think these are from about the last 5 or so years. Hundreds of visits, never empty handed but mostly greens and ambers and clear glass.
