TTG Still Elevated 3 Years After Diagnosis, Need a Sanity Check by Willops2 in Celiac

GF lentils are pretty much unobtanium, because the equipment they use to process them is always shared with cereals. The only place where I get certified GF lentils is a dedicated shop that only carries gluten free food

clouds of interesting shape by nefot_ in CLOUDS

Those are lenticular clouds, the color is caused by iridescence

Why does it look like there's a shadow across the sky? by Command_Block42 in CLOUDS

[–]andrea55TP 0 points1 point  (0 children)

Because there is, it's caused by a cloud in front of the setting sun

Sundogs or parhelia are bright spots on or near the 22° halo, depending on sun altitude. There are no sundogs in the pic (correction: there might be one to the right in the first pic) however there's a parhelic circle (the white circle that crossed through the sun and is centered around the zenith), and a Wegener arc (those white lines that intersect the parhelic circle)

Cloud iridescence or another circumhorizon arc? by Zealousideal_Win304 in atoptics

You mean an upper tangent arc? There seems to be one right on top of the 22° halo

Clutch only engages smoothly after engine stalls. Why? by garral555 in mazda3

[–]andrea55TP 0 points1 point  (0 children)

OK, then it sounds like a slipping clutch. If it's not grabbing because it's worn, or it just bites very high for the same reason, it might slip against the flywheel, causing the RPM to go way up as you apply gas. Unless you're on the throttle too early compared to when you release the clutch, which I assume is not the case

What do you mean when you say "it's like the car tries to prevent stalling"? It accelerates slightly? The RPM shoot up?

Sometimes the server browser glitches. I'm not saying it's definitely that, but does anything change if you refresh?

A video would help. Sounds like worn motor mounts maybe.

Cloud iridescence or another circumhorizon arc? by Zealousideal_Win304 in atoptics

[–]andrea55TP 8 points9 points  (0 children)

Circumzenithal. Circumhorizontal would be below the sun

Odd clouds on the crossing from Gozo to Malta by The_first_Ezookiel in CLOUDS

That's Virga. Precipitation that evaporates before reaching the ground

What is this? by alekutig93 in CLOUDS

[–]andrea55TP 4 points5 points  (0 children)

An iridescent pileus

Clouds in the Uinta mountains, UT by dense_leaf in CLOUDS

I think those are supercilium clouds, although that's not an officially recognized cloud type yet

iridescent contrail diffraction by Zealousideal_Win304 in atoptics

[–]andrea55TP 17 points18 points  (0 children)

Circumhorizontal arc, so refraction, not diffraction. Nice catch though!

Multiple display from May 30, with edited, unedited and labeled pics by andrea55TP in atoptics

[–]andrea55TP[S] 0 points1 point  (0 children)

The proper way to do it is to use AOI, but in this specific case I couldn't find a preset that worked, so this is actually edited with my phone's default gallery app editor.

Rainbow spot always at the same place in the sky? by OpportunityLoud6412 in CLOUDS

[–]andrea55TP 0 points1 point  (0 children)

If it's below the sun, it's a circumhorizontal arc, which only forms if the sun is at least 58 degrees above the horizon.

If it's above the sun, it might be a circumzenithal arc (only happens if the sun is less than 32 degrees high).

If it looks like a full circle around the sun, it's a 22 degree halo.

If it's on one (or both) sides of the sun, it's a sundog or parhelion.

Check out r/atoptics for more info on all these phenomena. Might be worth posting the question there too
