#photosphere — Public Fediverse posts

For the first time, #KelvinHelmholtzInstabilities 🌀 have been directly observed in the #Sun’s #photosphere ☀️🔭

#DKIST images reveal tiny #vortex-like structures at the edges of #MagneticFlux concentrations. #MHD simulations reproduce them and show that shear flows along these #magnetic boundaries trigger the instability.

Introduction

https://piefed.social/c/360cameras/p/1901799/introduction

The new #Kreutz #comet discovered unusually early has been named C/2026 A1 (MAPS): https://www.minorplanetcenter.net/mpec/K26/K26BC9.html - see https://www.spaceobs.com/en/Alain-Maury-s-Blog/The-discovery-of-comet-C-2026-A1-MAPS for the discovery story and http://www.cbat.eps.harvard.edu/iau/cbet/005600/CBET005658.txt and https://www.facebook.com/groups/227002358661288/posts/1670699484291561 (!) and https://groups.io/g/comets-ml/topic/117373975#msg34667 for diverging views about its chance of survival when it races a mere 160,000 km over the #photosphere on 4 April and becoming a bright comet.

I've an extremely niche #video question.

I have a 360 / spherical camera. When I grab the videos from its SD card, they come out like this - fisheye format.

Is there an easy way to turn them into #EquiRectanguar format suitable for #photosphere viewing? I'm using Linux.

If I use the official camera app, it converts them. But the app doesn't work on modern Android phones!

Help, advice, and speculation all welcomed.

‪Here are some great shots from our #GREGORSolarTelescope observation campaign in July. Peering into the #photosphere and #chromosphere, we caught several emerging active regions – and a #flare! This will help us study the plasma dynamics in active regions and how energy builds up to create a flare.

Wow, that’s an incredible image!

The International Space Station (. #ISS) silhouetted against the Sun creates a striking and surreal visual, almost like a scene from a sci-fi movie. The golden hues of the Sun’s surface, likely its the #photosphere.

[Pour le plaisir des yeux ... 🤩 ] Avez-vous vu ces images de la surface visible du #Soleil - la #photosphère - récemment acquises par les instruments embarqués à bord de la sonde #SolarOrbiter de l' @esa ?

Ces trois images témoignent de la #dynamique de notre Soleil - notamment, des mouvements de #plasma à sa surface, de l'#éjection de matière depuis les #tâches sombres le long des lignes de champ #magnétique.

OMG, I'll finally be able to make my self-hosted public online #Panorama #PhotoSphere gallery!!!

The City has recently poured some love into this once overlooked park, with new public restrooms, playground equipment and a fancy sign about the extensive cycling routes that locals have been toiling to build. The cycling road seemed to be in heavy use for the Golden week holidays.

J'ai une #photosphère avec mon téléphone, c'est rigolo.

Dans la galerie du synology ça donne bien une photosphère. Vous avez une idée de comment la poser sur Internet pour que ça continue de faire une photosphère ? (une photo qu'on peut tourner dans tous les sens).

[#Eclipse of April 8, 2024] Here are a few shots of the #Sun eclipse of April 8 over the North American continent.

The #photosphere, a few coronal mass ejections and various (dark-colored) spots scattered across the surface reveal our Sun's current activity. Maximum expected in 2025! Our instruments - aboard the #SolarOrbiter probe and installed at the #PicduMidi Observatory - are ready!

[#Eclipse du 8 avril 2024] Voici quelques clichés de l'éclipse de #Soleil du 8 avril dernier au-dessus du continent nord-américain.

La #photosphère, quelques éjections de masse coronale et diverses tâches (de couleur sombre) disséminées à la surface témoignent de l'activité actuelle de notre Soleil. Maximum prévu pour 2025 ! Nos instruments - embarqués à bord de la sonde #SolarOrbiter et installés à l'Observatoire du #PicduMidi - sont prêts !

What will make the #eclipse spectacular tomorrow is #solar activity. With the #photosphere blotted out by the moon, we will be treated to a view of the larger solar atmosphere including outbursts from its surface. This #SOHO image is in #ultraviolet but bodes well for immense activity off to one side of the #sun tomorrow.

The other treat is, of course, seeing #space (stars, etc) during the daytime.

What's cool about this picture is that you can estimate the rotation speed of the photosphere of the #sun The sunspots off to the right were face-on about 7 days ago. Now they have made a 1/4 rotation. So from that you can estimate that the sun's #photosphere rotates once every 28 days. The correct number is 28, on average! The equatorial regions rotate more quickly than the polar regions (25 vs. 38 days, respectively)

Now bring back the Tiny Planet feature! 📸

Google brings back Photo Sphere to Pixels, but there is a catch

The beloved photography feature is only coming back to Pixel 7 & older

[T]he option to take Photo Spheres is back on Pixels that previously supported the feature. This means that Google’s latest phones, the Pixel 8 and 8 Pro, are still left without the beloved functionality, but at least it’s back on the Pixel 7 series and older.

@manuelvonau #PhotoSphere #Pixel

Can someone who has updated to the latest version of the #Pixel camera tell me if it still has the #photosphere feature? I've been hearing rumors about the #Pixel8 not having that feature anymore and I don't want it to go away.

⚡📸 PhotoSpheres! 📸⚡

these are my favorite photospheres I've taken with my humble smartphone, the first in a park named: "El cedral", and the second in a desert named: "dunas de yeso", both using the Gcam, so I hope the next one I take is on a starry night... ✨

All of my latest solar images were taken with a telescope that has specific filtering capabilities in the infrared region of the spectrum. Thus, at different wavelength of lights, different features can be observed. On the infrared region (specifically the hydrogen alpha emission line at 656nm), the solar chromosphere can be seen as a hellscape of "flaming features" called prominences. On the other hand, at 540nm (in the green region), the #photosphere can be seen instead. (1/x)

Anybody know if there is a way to display 360/180 "Photospheres" natively on Mastodon ?

I did a bunch of PhotoSphere panoramas with the Pixel 6a last night as the lights were coming on in the city, and if there's a way I could get Google's attention, I would ask that there be a way to adjust the exposure before starting the process of recording images, because it makes all the difference in the world between acceptable and not.

Here's one I did of Cupid's Span before the sun went down.
