APOD: A Sunrise at Sunset Point (2023 Oct 19)

[APOD Robot]

A Sunrise at Sunset Point

Explanation: This timelapse series captured on October 14 is set against the sunrise view from Sunset Point, Bryce Canyon, planet Earth. Of course on that date the New Moon caught up with the Sun in the canyon's morning skies. Local temperatures fell as the Moon's shadow swept across the high altitude scene and the brilliant morning sunlight became a more subdued yellow hue cast over the reddish rocky landscape. In the timelapse series, images were taken at 2 minute intervals. The camera and solar filter were fixed to a tripod to follow the phases of the annular solar eclipse.

Very very beautiful image! Exquisitely fine details, extremely rich colors.

But where is the new moon? Surely it can't be that brilliant light at the horizon?

Excellent post! This is a fantastic blog that I will definitely return to throughout the year driving directions

2 minute intervals ? Sun images do not overlap, isn't it rather 3 or 4 minutes ? Maybe I'm wrong. Very nice picture by the way !

Great picture of the eclipse and Bryce Canyon! I found three groups of other eclipse watchers in the full-size photo. Could be more.

More like the Sun caught up with the new Moon.

So you mean it is in the picture? Where?

The Moon rose first... just over a degree ahead of the Sun. Far too lost in the bright sky to be seen in this image. The new Moon only becomes visible once it starts occulting the Sun, which occurs because it is moving slower across the sky and the Sun "catches up" with it. Of course, the actual new Moon is what we see when the Moon sits directly in front of the Sun. On either side of that it's actually a waning then waxing crescent.

I assume what we're seeing on the horizon is the sunrise itself, captured in a frame taken about two hours before the eclipse sequence begins.

I think I agree. Both the Sun and Moon are about 0.5 degrees wide, and the Sun moves about two widths per photo, which means it's moving 1 degree per photo. The Sun takes 24 hours to travel the full 360 degrees in the sky, so 24*60 = 1440 minutes / 360 degrees = 4 minutes per photo.

So, are we both right or both wrong?

Uh... yeah... that's where it is...

Another way of looking at it. The eclipse spanned 3 hours, and is segmented into 44 parts here. 180m / 44 = 4m.

Nice! Which means the photographer is mistaken on his Instagram post about the photo.

Can anyone tell me why there seems to be a white-ish glow in the sky behind the tree?

A processing artifact. Some tool similar to Photoshop's "clarity" setting was used to enhance the sky, and it avoided the edges created by the tree.

Well that explains it!
Thanks Chris
