- On the morning of June 24th, 2023, I recorded the sun's activity for three hours using a telescope that filters all light but a narrow band of red light given off by excited hydrogen gas.
This video has no commentary or additional clips, only the timelapse sequences. For full commentary and comparison with various timelapses from NASA's Solar Dynamics Observatory, see • Three Hours of the Sun... . - Наука та технологія
This is beautifully stunning
Great video!
How could anyone dislike this video??? Breathtaking!!!
This is awesome … and a little frightening. Please do more of this!!
Yes, I was also feeling it beautifully frightening.
I once had a Coronado PST, but your detailed video is reminiscent of filming with large scientific telescopes!
I recognize the video from Goddard
EXCELLENT !
Outstanding!!!!
Great .... I was feeling scared but still I enjoyed watching it. I'm totally an ignorant in astronomy and astrophysics but somehow out of my deep interests in the study of anything infinite (e.g., our grand creation), I once joined a course in Birla Planetarium, Kolkata for it was offered to people like us from different backgrounds and my experience was amazing. I don't have a telescope but once we were taken to a remote village, far away from Kolkata for enjoying a star-party (they called it) and there the sky was clear enough to see the celestial objects through the telescope and we enjoyed our deep sky observation along the whole night. At the end, we were sharing our experiences and someone said very beautifully that till then he only had an idea that in case of ocean, there were deeper levels of its existence but it was beyond his imagination that even the sky also has such deeper (or farther probably) levels of existence. In fact, in case of an ocean it's finite but in case of sky, it's vastness is extended to infinity. I was reading all the comments here and I was feeling happy to see that i could connect with many of the concepts. Thank you. 🙏🙋
What you're looking at is a single wavelength of light being observed from the Sun called Hydrogen Alpha aka H(α) ( which is 656.3 nanometers in the EM spectrum ). It's basically a way to get around the intense white light washing out all the details of the Sun that you'd normally get from a regular white light solar filter. With a H(α) filter, all the " glare " gets blocked so you can see the full details of the Sun's surface features along with the prominences and plasma activity in the magnetic field lines. The only time you can observe prominences or particles following magnetic field lines in the Sun's atmosphere with no filter is during a Total Solar Eclipse.
Beautiful.
(It looks like an orange one wd eagerly eat !!!).
Great video, very impressive, like it!
It is surprising to see something like an atmosphere, around 3000 km thick if my estimation is correct.
It's actually much bigger. 8 Million Kilometers above the suns surface
At 1:14 one can see a red line around the sun, half the earth hence 3000km.
Maybe we cannot see the whole sun's 8000000km thick atmosphere on this video, I'm certainly not an expert.
Dose no body see all the faces on the sun pictures on the soho all the time xxits the sprit realm V xxlove love from new zealand 🇳🇿 xx 🇳🇿
me imagino que habras publicado en algun sitio las imagenes procesadas, la verdad que con lo que pude rescatar del video hay muy buena informacion!!!!
Really well done, and great capture. I have the same scope and have not gotten such detail as you have shown here. I'll blame the jet stream for my poor results (or more likely pilot error). could you say what camera you have and what Barlow if any? Congrats!

3 Hours of Sun...
in 4 minutes.
Three hours in 8 seconds.
Each clip is the same animation of the same 3 hour period, repeated twice for clarity, and zoomed in to focus on something specific.
Ecco tre ore in otto secondi😮
I've watched videos on stacking planetary pictures for like Saturn and what not. How do you get motion aka make videos? Neat video btw.
Each frame is 1 minute of stacked images, then the frames were stitched into a sequence.
im a new astrophotographer, i have a setup similar to this but don't get anywhere near this quality, is there somebody i could talk to on how to improve my setup/process? im in the dfw area
There are many in our club who do solar imaging. Meetings are at 7pm on the third Tuesday of the month at the UNT Health Science Center Research and Education building, 1055 Montgomery St, Fort Worth, TX 76107.
This was done with the Lunt 80mm. Make sure your etalon is tuned. I use a mono camera, 0 gain, 2.5ms to 5ms, depending on the sun's altitude.
Focus on the edge of the limb first. Open the tuner, crank it all the way down, then open it back up slowly to about half-way. Stop when you get see a lot of contrast.
I record an SER for 1 minute, then repeat over and over to get the timelapse. Stack each SER and take the best 5-25% of the images. Then process as you like.
I have some action in Photoshop I use for automating hundreds of frames for color and clarity.
@@FortWorthAstronomicalSocietyAwesome! I am in Richardson myself and just ordered an Lunt 40!
Very nice
Is that single stacked?
Yes, I did not try with the second etalon. That will be a test for the future.
I've seen many videos of the Sun, and a reason why i keep looking is : I'M TRYING TO , MENTALLY, GRASP WHAT IT IS !!! AND HOW IT STAYS TOGETHER (they say it's just a Giant ball of Nuclear Gas(s) )
Stars are a balance between fusion energy trying to blow the star apart, and gravity trying to squeeze it together into a tiny point. The stars burn until there is an imbalance.
А потом нам говорят что в газовом шаре Солнце образовалась большая трещина.
Как в газовом шаре может образоваться трещина?
Это возможно только на твёрдой поверхности.
Они сами не знают что такое солнце..
@@FortWorthAstronomicalSociety OKAY, i think I'm getting it, thx for that.

Coronal holes are not "cracks". Whoever used "crack" as a description was not being accurate in their description.
This, my friend, is what the sun really is: ua-cam.com/video/9uhiGOEa_pc/v-deo.htmlsi=LgIikwiOzfapiqfq
Can you provide more information on what H-Alpha filter you used, was it a 6 nm?
This was a Lunt 80mm Ha telescope, single etalon with a .65 Angstrom bandpass.
Do not use an astrophotography Ha filter for solar viewing, it will not give you good results. I have tried.
@@FortWorthAstronomicalSociety That cost almost $5k 😭
@@FortWorthAstronomicalSocietyhow many times magnification ?
4000x?
Thanks
@@CrazyFunnyCats We rarely bother with calculating magnification - the resolution of an image is more important.
@@FortWorthAstronomicalSociety you need high magnification for good resolution on far away objects.

Strange there is no visible rotation yet you see CMEs.
If you look carefully, you can see the rotation on the zoomed-in edge views, from left to right.
There are no coronal mass ejections visible in this short timelapse. Afterwards, there was one from the prom in the SW edge.
Smog rays! Lite gravity?
The sun is not that big.Some suns are millions of time bigger.And they are silent. It is very strange .
I think the smaller the star, the more active it is unless it’s a white dwarf or black dwarf (fully dead star with no fuel left)
The Sun controls earths climate period!
But experts blame cow farts 🐄💨
The earth's climate is dependent on many things, not only the solar flux. Greenhouse gases are a major factor in the average temperature of the planet. We can see this through geologic records, especially during the Snowball Earth periods, the Oxygen Crisis, etc.
The End Ordovician extinction event had the uplift of the Appalachians, an increase in weathering and flow of minerals into the oceans, blooms of the plankton of the time, and sequestration of CO2 in their shells, changing the chemistry of the atmosphere and the oceans.
The Late Devonian extinction event was caused by the growth and diversification of land plants, sequestering CO2 and generating rapid and severe global cooling.
The End Permian extinction event was due to massive volcanic activity in Siberia. This caused global warming from elevated CO2 and sulfur (H2S) levels from volcanoes, leading to ocean acidification, acid rain, and other changes in ocean and land chemistry.
The End Triassic extinction event was due to enderwater volcanic activity in the Central Atlantic Magmatic Province (CAMP) caused global warming and a dramatic change in the chemical composition of the oceans.
End Cretaceous extinction event was due to the asteroid impact in Yucatán, Mexico, causing a global cataclysm and rapid cooling. Some changes may have already pre-dated this asteroid, with intense volcanic activity and tectonic uplift.
Our planet is a complex system that is stable only in the short term, and is easily destabilized when just one or two variables are changed.
@@FortWorthAstronomicalSociety We we’re giving the short version comment, lol, you have good info there, However, the politics and fake msm news is brutal. Ie) carbon capture trying to lower C02 on earth reduces Plants and vegetation etc food growth. There already is a food shortage on earth in many regions. Plus we’re going into a mini ice ice age due to grand solar minimum.
Suspicious Observers channel if you want some info on that subject
You can’t learn what you don’t want to know. 😢

Some people said the real sun colour is white. is that true?
The sun's color is white, to our eyes. But we classify it as a "yellow dwarf" based on the temperature.
For these images, we color them yellow or reddish so that our eyes are better able to see the contrast. For hydrogen-alpha images, the color really is a deep red, even deeper than the color we tend to use for aesthetics.
It burn your xxx 😮 😂
you mean 4 min :V
3 hours in 8 seconds. Each frame is a stacked image from 1 minute of capture.
Each clip is the same animation of the same 3 hour period, repeated twice for clarity, and zoomed in to focus on something specific.
The awesome power. How is this not our God? F the priests

I would rather see it in real time. Why does everything from the Aurora to solar videos have to be sped up? It's as if nobody has any patience for the natural speed and beauty of our world anymore.
The realtime view is rather boring. It takes minutes to see changes happening, so slowly that we just realize something is different well after the event happens. The actual velocities are quite large, but the scale of the sun is even larger.
An analogy is watching a hurricane from space. The winds are fierce at ground level near the eye, but from far away, the motion is barely perceptible, and only with a timelapse do some motions and patterns become obvious to us.
Incidentally, there are a number of aurora videos that are not timelapses at all, but in realtime. Most people do not even realize it because we just expect the apparent motion is "supposed" to be slow.
@@FortWorthAstronomicalSociety Thank you. I know I'm unusual but barely perceptible is what I want, because it's 'real'. We've all seen time-lapse vids of plants dancing as they grow, but if one is very still, you can see it in real time, and I used to watch it (my sunflower greens, indoors/ no significant air movement), but you just have to be still and patient. Again, not for everyone, but call it an exercise in stillness.
You can actually see your plants grow? You must have some serious autism.
@@MountainMetaldo you watch paint dry too
@@REMdonor No, but I sometimes watch plants dance as they grow, normally only seen in time-lapse. It requires an unusually still mind, and body... and still air, of course.
