In (or over) the rainbow

[[email protected]]

On my last GA flight where I acted as safety pilot on an IFR flight
plan, I got a video
of our shadow on the clouds. So, I will letchya all decide in 43
seconds or less if I was over or in the rainbow

For those interested, the technical name you are looking at is called
a Glory.

I found it fascinating how the size of the glory changes dramatically
based on distance from the cloud tops.

There's nothing particularly odd about that. Rainbows and glories will
always be exactly the same angle away from your own shadow.

What is useful to know is that the glory will be present or not
depending
on whether you are looking at ice crystals or water crystals. As I
remember,
no glory when looking at ice crystals.

So if it's below freezing and you have a glory, look out.

Thanks!!!

Fully understand and never intended to imply it was odd, but only time
I have seen this is on level clouds, not seen it on varying cloud
tops, thus me finding it fascinating as the varying degrees of the
irregular surfaces made it interesting to see the image zoom in and
out which I have never seen before.

....but something you may want to verify before making a descent/no-descent
decision (i.e. having it in your IFR toolkit). I'm just saying...
