Firefly Aerospace's Blue Ghost lunar lander witnessed a solar eclipse during what we on Earth saw as a total lunar eclipse on March 14, 2025.

Wow, because it makes no sense to me. No doubt, I'm missing something given that's an actual image.

Seen from the Moon, the Earth has an apparent diameter of 104 arcminutes, which is over 3x that of the Sun, so how does one get such a full ring effect? The ring effect comes only when the sizes are essentially the same.

Is this a composite?

It’s more obvious that our atmosphere can refract in such a way to do this. But it’s surprising to see.

The only "Diamond Ring" is at 4 o'clock where the Sun is. The rest of it is the Earth's atmosphere. For this eclipse the tangent line ran N-S through Brazil and Eastern Siberia. The rest was over oceans. Those land areas get forest fires, make the light even more reddish. I watched it through big binos, it had a nice reddish tint plus a blue area where the Sun was almost exposed.

Thanks Bill.

At first glance, it looks as if we are seeing prominences (ring), though blurred, along the limb, hence my question.
