APOD: A Total Solar Eclipse Close-Up in... (2017 Sep 12)

Postby APOD Robot » Tue Sep 12, 2017 4:07 am

Image A Total Solar Eclipse Close-Up in Real Time

Explanation: How would you feel if the Sun disappeared? Many eclipse watchers across the USA surprised themselves with the awe that they felt and the exclamations that they made as the Sun momentarily disappeared behind the Moon. Perhaps expecting just a brief moment of dusk, the spectacle of unusually rapid darkness, breathtakingly bright glowing beads around the Moon's edge, shockingly pink solar prominences, and a strangely detailed corona stretching across the sky caught many a curmudgeon by surprise. Many of these attributes were captured in the featured real-time, three-minute video of last month's total solar eclipse. The video frames were acquired in Warm Springs, Oregon with equipment specifically designed by Jun Ho Oh to track a close-up of the Sun's periphery during eclipse. As the video ends, the Sun is seen being reborn on the other side of the Moon from where it departed.

Superb
But IMO no less important parts are the voices and the music. Efficiently, they render no fear in their awe just acknowledgment to beauty of the event. I don't speak Korean (I think it is) and sound of voices are just perfect and sufficient to conduct emotional state facing this experience. Music is perfectly timed too.
Thank you

That is an awe-inspiring and highly educational video. I just had to watch it repeatedly, and then go back and replay certain parts. At the C2 point, the details of the lunar edge are amazing. I was surprised at first that you can't see the mountains of the Moon extend past the limb of the Sun, but it makes sense -- there is no light to show them once they pass that arc. After totality, once the aperture is changed to capture the corona, you can again see the irregularities in the lunar edge. Then, at the C3 point, as the Sun begins to emerge again, the diffraction in the light is really amazing and so beautiful.

I am not certain if this is an artifact, but I think I can see some variations in the corona as the video progresses. But with the camera motion and changes of settings, I cannot be at all certain about it. On this time scale, the prominences appear as frozen features.

At request, I swapped the video for an identical one that gives attribution to KAIST directly on the video itself. The old video also started automatically, but I turned that off.

I noticed that the diamond effect was switched left-right. This movie had it at clock positions 5 and 11 in that order whereas I would expect it to be at 7 and 1. Is it just a case of how the camera is mounted?

Cool diffraction images as the "slit" gets smaller.

Absolutely gorgeous! I'm amazed at how moving it was.

Wow, like owlice said, goosebumps!! again!!! Comparing the voices in the background with my memory of the event, I'm sure it's just a difference in the sheer number of people witnessing, but where I was (University of SC campus) there was just overwhelming cheering as C2 approached, then the collective gasp when the diamond ring appeared. Still, this is an amazing video of something I got to check off of my bucket list...

Thank you!

Where I observed it there wasn't anybody within sight or sound, so for me this was entirely an expression of nature. Interesting to see videos made around large groups of people. Both ways of experiencing an eclipse have their merits.
