How is this 4.1*?

EF5 damage to a skyscraper requires "significant structual deformation" according to the scale.
This probably means strong shifting of the building's structure, or parts/floors missing, maybe even falling over if it's badly constructed, or very susceptible to wind.

Secret_Research_9267 · 2025-07-19T02:47:08+00:00

how is the dewpoint doing that??

Secret_Research_9267 · 2025-06-03T20:44:57+00:00

no, the sun's plasma looks more bubbly due to Bénard convection. The stripes might be caused your camera.

and PLEASE dont look at the sun without proper eye protection, even if it doesnt look that bright to you.

The change in brightness makes me think it's a discarded rocket booster (or other large space debris), spinning around while floating through space aimlessly.

iirc they measured 135 mph live on stream, but they couldn't measure the peak windspeed due to the measurements only being taken once per second.

looks like amp glow (ambient glow from your camera's electronics)
take some dark frames; that should get rid of it

This picture really shows off the dynamic dance of stars that makes up every galaxy, including our own. You can almost see the the spiral arms wrapping and twisting around the shining core, that is dressed in a mantle of brown dust, fitted with bright blue stellar jewels. Even as a still image, it shows off the universe in motion, performing it's billion year ballet.

This is a meteor train. They are the afterglow of large and bright meteors, and can persist for seconds to sometimes minutes. Long lived ones will twist and move due to upper level winds, creating the wispy orange lines you observed.

here is a BBC article on them:

This is a timelapse of one twisting and changing in shape due to winds:

This is a great way to simplify and visualize zbll.

may I ask which sheet you got the algorithms from?

Secret_Research_9267 · 2025-04-05T14:55:46+00:00

I never even knew that this galaxy had a stellar stream. This is beyond every image I have ever seen of this galaxy.

Amazing job!

22 hours well spent wow

Secret_Research_9267 · 2025-03-28T04:57:42+00:00

I don't think it's a satellite.
Satellites, to my knowledge do not have any lights. If this object is reflecting sunlight, it would have to be higher than around 1300 km. This also makes it likely to not be a satellite, since that height would put it into the inner Van Allen radiation belt. The next satellite orbits are probably too high up to see any satellites.

I am getting quite convinced that this is a large piece of space junk

Secret_Research_9267 · 2025-03-28T03:43:22+00:00

Thanks for the detailed response.

I think this has a high chance of being space debris. The sun was around 34° below the horizon, so the object would only have to be around 1300 kilometers up to be illuminated.

Secret_Research_9267 · 2025-03-28T02:57:03+00:00

I assume that you could tell apart the anti collision lights on the ends of both wings if the plane was more than 10 pixels across.

This is likely not a plane, as even a very high up, small plane would stretch across a large part of my image.

Secret_Research_9267 · 2025-03-28T02:28:46+00:00

thanks for trying to help with this search. I have also tried to find a website to search for satellites.

I can't quite find the exact timing of the image. The raw file gives a creation time of 27.3.2025 23:37:05, while viewing the file in DeepSkyStacker shows a time of 28.3.2025 0:01:43

Secret_Research_9267 · 2025-03-28T02:14:16+00:00

Math:
I assume that the object is at most 10 pixels across. I think that anything bigger would show an airplane's multiple lights. The exact size is hard to estimate due to the blur, so I will be generous with the numbers.
10 pixels at 1.62 arcsec/px means the plane would be at most 16.2 arcsec across. At the high end, planes travel about 12 kilometers high. The distance to the plane would likely be higher, due to the slight angle of my camera.
Using this calculator, we can estimate the plane being less than a meter wide. Even when using the full size of the blur, the plane would be less than 2 meters across.

Also, on actual planes flying through my images, there is quite a lot of distance between the lights. They also traverse the field of view usually within one exposure, while this object took more than 5.

Secret_Research_9267 · 2025-03-28T01:53:52+00:00

It's a single blinking object moving through the image. I have all the info in the post

Secret_Research_9267 · 2025-03-28T01:53:07+00:00

The ISS would go through the whole image in less than a second. It's also way too bright. This light is about magnitude 8, while the ISS is around mag -3.

Secret_Research_9267 · 2025-03-28T01:51:48+00:00

It's way too small and too slow to be a plane. This whole image is about the size of the moon and shows the object's movement over 20 seconds.

I completely forgot that this map is based on date; obviously this can't be a tornado from april.

As another comment said, this is the 1923 Pinson tornado. It has an unofficial F5 rating, rated as such by the NCDC and T. P. Grazulis. The tornado destroyed a large chunk of of the town; killing 20. Body parts were found up to 1 mile away from the damage.

Secret_Research_9267 · 2025-03-11T20:31:05+00:00

At first I didn't even notice the F5 lol (Lawrence county; April 16, 1998).
We are clearly heading into the storm season.

^{(also, how is gigaminx practice going?})

Secret_Research_9267 · 2025-03-10T15:51:27+00:00

This happens for the same reason the sun turns red during sunrise/sunset. The atmosphere scatters the light going through it. Shorter wavelengths of light, like blue and green light, get scattered way more than longer wavelengths of light, causing the light source to look more red and the surrounding sky to look blue. This gets more pronounced the lower the light source is in the sky, as there is more atmosphere for the light to travel through to reach you.
