Atlas V launch, November 13th 2020, from Cape Canaveral with NROL-101 spy satellite.
The lower part of the launch trail is shaded by the globe, while the upper part is lit by the sun.

Article: Morning Glory
Posted on December 13, 2011by Shannon Winslow
This sunrise this morning, framing Mt Rainier (with its shadow cast on the underside of the clouds), made me wish for the eloquence of a poet to describe its glories.

I'm sorry, you're correct.As far as I know, there is no high hotel on the northern end. I assume you mean the southern end (New Orleans side). Probably the Marriott and looking north?
Eric Brummel has 3 of these on his youtube channel.You can do a video like this with any equatorial mount, which is basically a tripod with a motor-driven mount that spins a telescope (or a camera) at the exact rate the globe turns (~359°/day). You need to adjust its tilt to your location so that the axis of spin is perpendicular to the equator, hence the name.
Augmented such that "a sufficiently large dome" (so with negligible paralax) wouldn't be a counter-example.P.S. the stars look the same (no distortion) from any place on Earth where you can see them but the stars that you can see differ. This is not possible with a dome.
I really don't want this to be a discussion thread, so let me just point out the sun and the moon tracks in the "star-stabilized sky" video: they don't have parallax against the "star dome" (except for a tiny bit).Augmented such that "a sufficiently large dome" (so with negligible paralax) wouldn't be a counter-example.
I wish somebody with such a camera would recreate this with a bowling ball or other smooth ball. The "horizon" of texture bumps (pebbling?) allow somebody so inclined to see visible curvature. I'm curious if that would be true with this sort of camera on a smooth sphere.Here's a picture showing the apparent absence of curvature on a curved object:

You had the exact same idea 22 months ago, in post #9.I wish somebody with such a camera would recreate this with a bowling ball or other smooth ball.

Well shoot...You had the exact same idea 22 months ago, in post #9.
External Quote:While this does show our beautiful round shadow, it's actually a bit misleading. Earth's umbra (the darker portion of the shadow) is much smaller than our planet's diameter, so in composites like this it doesn't truly show the scale of our planet. The dark part of the shadow was about 2.7x the width of the moon, while Earth is actually about 4 times the width.
The shadow turns red due to the light scattering through our atmosphere. If you were on the moon, Earth would look like a red ring (with a solar corona around it). When we have permanent lunar residents, we'll be able to get photos of the event from the lunar surface!

I also wrote a little blog about how I got into this hobby if you're curious what it might take to get started, on my website here.

There's an animation by NASA's Scientific Visualization Studio "September 27, 2015 Total Lunar Eclipse: View from the Moon", https://svs.gsfc.nasa.gov/4341#22148. It would be really great to see the same live.View attachment 56242Hey NASA, I know you are reading this thread -- when it comes time to schedule a lunar landing, maybe keep this in mind. Would be really cool.
Basically a colossal pizza.Im not sure what flat earth believers think the earth is? A cube, A disk/square of X km thickness, whatever it is,
The one theory I've often seen going around is that the sun is a massive spot lamp that moves around the flat earth. I don't know the exact details (such as how this explains sunsets) but I know that this is one of the theories.but nothing stops this from occurring on a flat surface, actually thinking about this now(*) how do flatearthers account for different timezones, how is it dark here now whilst I can ring my family and it being day time (just measured and its 505km away from the antipodes of where I am now)
I've always tried to but I usually end up inevitably running into it, although amazingly I've never met anyone at any of the Colleges I've attended who believes in the Flat Earth theory. They'll believe a whole bunch of other conspiracy theories but the Flat Earth theory almost never gets mentioned.(*)honestly I've always give flatearth beliefs as much of my limited time as I do photos of UFOs with lights on them, bugger all
