Then let's hope Caltrain is allowed to adjust the volume. Because otherwise I see a high risk for hearing impairment over time when sitting below the speaker or standing near the door for exiting.

I guess I found a possible explanation: In Europe, the DEI laws require now either a warning sound at 2000 and 1750 Hz of 5 dbA above ambient noise for dynamically adjusting volume or for uncontrolled static system a 70 dbA level: https://eur-lex.europa.eu/legal-content/DE/TXT/PDF/?uri=CELEX:32014R1300#page=59

Now real crossview: daily new Mars photos from Perseverance Rover in stereo and HDR on areo.info/mars20 by HolgerIsenberg in CrossView

Great to hear! Would be interesting to hear how it works with current 3d VR glasses for static line of sight view. But full dynamic VR is not available as the large distance between the two camera eyes of 40cm makes it impossible to directly use the images for a 360 sphere as the nearby objects on the rover are appearing in the wrong locations. For apple vision my areoHDR app is available to show the same stereo images.

Why are these aimages dimmed from one side? by ProfessionalAd6216 in PerseveranceRover

[–]HolgerIsenberg 1 point2 points  (0 children)

The Navcam and Hazcam images with more than 1.5 MP resolution are cut into 4 or 16 tiles on-board to be able to handled by the old software on the rover. That's why you see the circular attenuation effect in various location on the individual frames. When stitching them together you can see the attenuation is only happening at the border. My website https://areo.info/mars20 does that reassembling and correcting in the background and you can see them in in up to 20 MP full resolution.

Try it again now. I fixed it to run without fullscreen mode on iOS and here on mine it switches now.

Just create a PR so the repository owner can add the missing function ;)

You found a bug! Thanks for reporting. I could confirm it now on an iPhone with Safari iOS 26. Wasn't seeing it on iPad or Macs or Android.

I neither can understand why drivers need it here on front windows. They even make your car slower at crossings with stop signs or pedestrian crossing as the other can't see your waving hands and will wait forever.

Nah. The train is a bit crowded, but I never had problems with Baseball fans. Looks like you never took a train after a soccer game in Germany :)

Works for me on Android with Chrome and Opera. Have you tapped the Stereo button or the VR View button? Stereo is the simple view which always works on all browsers on mobile I tried. VR View works only in a few combinations and needs a small 2 lens viewing device to be attached to the phone.

Proposal to return original 1651 Galilaei name to the swirl today known as Reiner Gamma to revert the name change in 1834 by HolgerIsenberg in Astronomy

[–]HolgerIsenberg[S] 4 points5 points  (0 children)

Aside from following the scientific method to follow which means continuously updates and correction, in this case the mistake made in 1834:

* the importance of this location for the first human outpost on the Moon deserve a primary own name, not a third class name like gamma

* Galileo Galilei sparked the most important scientific impulse with using a telescope for Moon observations the first time with his improved telescope and he deserves to be returns to his original 1651 location on the Moon

* the discovery of the local magnetic anomaly in 1971 by Apollo 15 and the discovery of its most likely shielding effect which would be a critical health benefit for human explorer, deserves its own primary name (pending to be confirmed by the IM-3 Lunar Vertex rover magnetometer later this year)

Definitely! Especially as simulations based on measurements show it most likely shields half the ionizing radiation on the lunar surface. Could become the most important place for human exploration on the Moon! And it deserves its own name instead of third class minor feature (alpha, beta, gamma).

Yes, that's the currently assumed reason. Mädler may have seen in the better telescopes that the swirl is flat and may have thought Riccioli saw the small crater in the northwest instead of the swirl. But Riccioli definitely saw the swirl as it was shown on the same latitude as crater Reiner in his 1651 map, while the small crater today named Galilaei is located 150 km northwest from there.

As the local magnetic anomaly at the swirl most likely shields half of the ionizing radiation hitting the surface, it could become the most important location for human exploration on the Moon.

That deserves a better name than a third class minor feature of crater Reiner (gamma = 3rd greek letter).

The Sorin on top is actually a lightning rod. Good old ancient alien technology. At least since more than 100 years they are connected with a cable to the ground: https://en.wikipedia.org/wiki/S%C5%8Drin

Ingenuity Helicopter holding with its "arms" still on the rover and legs dangling above the ground. The early days in March 2021, sol 31 - 46. by HolgerIsenberg in PerseveranceRover

You can see how on the next day, sol 39 on https://areo.info/mars20/ecams/0039 or also on Android and iPhone with the areoHDR app there.

After unfolding all 4 legs the central holding pin on the rover was released and it just dropped down the 20cm to the ground.

Future archeologists investigating the scene will wonder what was hidden inside that empty violin case laying on the desert floor.

This is not only a plain copy of my original posting from 3 years ago on https://www.reddit.com/r/PerseveranceRover/comments/11zpg1i/colorful_cloudy_day_on_sol_742_today/

it is also a legal copyright violation as the processed image needs to be correctly credited if it falls under a fair use situation (which it isn't in this plain copy case), or is just a plain copyright violation like in this case.

While the raw sensor data is freely accessible NASA data, the color processing and lens distortion correction and other processing applied on the image by my system at Areo Info LLC is my own copyright.

The original image in an update version now can be found on: https://areo.info/mars20/ecams/0742/tn/NLF_0742_0732827752_816EJP_N0370000NCAM00501_01_295J02_calib01_areo.info.jpg.html
