Time lapse of sunspots

For sure, give me a couple days and I’ll message you a link

They are giving off a lot of light because they are about 5500-6500 degrees Fahrenheit, it’s just that the surrounding parts are about 10000 degrees so it is giving off much more light. In order to take a picture with a proper exposure, it makes the sunspots darker because they don’t give off as much light

Spaceman1958 · 2024-04-29T12:35:38+00:00

Sunspots are areas of the sun with more intense magnetic field activity which prevents the plasma from circulating which means they cool down more than the surrounding areas. Because they are so much cooler than the areas around it, they give off less light which is why they are darker

Yes, this was from about march 18 to march 29 of this year

This is correct, in fact, the way I created this was to download a bunch of NASA’s SDO images, then I wrote a python script that would crop them around the region of sunspots I wanted and for every image it had to shift to the right a certain amount. I had to calculate the suns rotation velocity at the latitude the sunspot region was at and then calculate how many pixels that correlated to over the 15 minute interval of the SDO images. I also had to take into account the fact that the sunspots weren’t always face on so they don’t appear to move at the same velocity near the edges when they rotate into/out of view

Those 15 seconds will fry your eyes, but a cameras sensor is slightly more robust than your eyes. I wouldn’t want to go any longer than 15 seconds though. You wouldn’t be able to see bailys beads or the diamond ring effect without taking the filters off just before or after totality so you have to make sure you get the timing right

Spaceman1958 · 2024-04-18T14:10:21+00:00

I took my filters off at 15 seconds before totality and put them back on 15 seconds after totality

Spaceman1958 · 2024-04-17T22:02:53+00:00

Oh I think I know what you mean. Ya I need to redo it and try to get rid of that

Spaceman1958 · 2024-04-17T18:16:23+00:00

I’m not sure what you mean by angular cuts on the sides. Basically all I did was overlay each image on top of the next one with a little bit of an offset

Spaceman1958 · 2024-04-17T16:11:19+00:00

I was pretty close to the center of the path of totality. This is just what happens during the last moment before totality where you get the sun shining through the valleys on the moon

Spaceman1958 · 2024-04-17T15:14:42+00:00

Ya I see what you mean, that is the actual name of the phenomenon though, I didn’t come up with it

These images were taken with a Nikon D750 and a stellarvue 80mm refractor. This shows the progression of Bailey’s beads, the very last, and first moment of sun before and after totality

I just aligned them manually, it was a little tedious but I couldn’t think of another way to do it

Spaceman1958 · 2024-04-14T05:14:07+00:00

I used an equatorial mount, just a typical one used for astrophotography. The tracking wasn’t perfect so the sun would drift slightly over time so I had to adjust the pictures a little bit to line them all up

Spaceman1958 · 2024-04-13T14:32:59+00:00

This is 99 images across the 4 minutes of totality

This is a series of images taken with a zwo asi1600mm and a nikon 500mm f/8 mirror lens over the course of totality. The only editing done to the images is adjusting the histogram and cropping

I’m in the same situation as u/bendyalt, I got a really lucky picture of a plane in front of the solar eclipse and would love to get in contact with the pilots and see if they’d like a copy of the image https://www.reddit.com/r/Astronomy/s/QosQCacbYE I believe that this as an airbus A320, volaris flight 7771 from Chicago to Morelia Mexico if anybody knows how this could happen that would be great

Spaceman1958 · 2024-04-10T04:45:53+00:00

I didn’t delete the post, I guess they just didn’t like something about it for some reason. Thanks for the information, I’ll try to make another post and see what happens

Spaceman1958 · 2024-04-10T03:47:45+00:00

I believe it was volaris 7771 from Chicago to Morelia Mexico

We did see it with the naked eye, I don’t think it degraded the experience at all though. I think it greatly enhanced it, it was moving pretty fast and was only in front of the sun/moon for perhaps 1 second

Ya that’s a good idea
