stellarium VS suncalc

They're the Plieades. For future reference you can check on what's in the sky with software like Stellarium.

Btw, seems it is gone because the account was deleted https://github.com/Stellarium/stellarium/discussions/3277 back in June of 2019

We have been experiencing distress and perplexity of nations upon the earth unlike anything in modern history. There have been record hurricanes, cyclones, typhoons, and flooding globally which appears to relate to “the sea and the waves roaring” and according to research using the Stellarium Astronomy Software, this was a one time alignment on September 23, 2017 involving the sun, moon, and stars that accurately matches the reading of Revelation 12:1-2 word-for-word, the last book of the Bible foretelling the end of the age.

Stellarium - Planning out targets and just seeing what's up in the sky on any given night

I did a bit of poking around using Stellarium and found two stars that I thought were admirable candidates, and I wasn't sure why Nell and Ruggles didn't think so: Phecta and Megrez, Gamma and Delta Ursae Majoris. These are the two stars that make the left side of the 'scoop' of the big dipper. According to Stellarium they were at their closest to being in a north-south alignment in the year -2586, that is 2587 BCE, with right ascensions differing by just 1.28 s (0.00036°). They were 15° and 20° from the pole at the time.

But if you need an API i think stellarium.org has an one.

If I wanted to build an app like Stellarium, displaying a 3D model, but not requiring fast animation, not a game, more visualization, what libraries should I be considering for the display/UI portion of this program?

A really simple, small package to manage React context around color scheme toggling. Specifically, you can switch color scheme manually or automatically, and if the latter you can follow either the system color scheme or the sun.

I based some of this code heavily on a couple Mantine (https://mantine.dev/) hooks and Suncalc (https://github.com/mourner/suncalc), but modified them to either make them simpler and/or, in Suncalc's case, typed.

This is my first open-source package in a while, so I'd greatly appreciate any constructive suggestions! I have been using some form of this in my own projects and figured, when I added it to the most recent one, I should just extract it into its own project. I'm hoping something small like this will motivate me to do more open-source work because I miss it!

It would be fun to see this with local daylight hours mapped to the squares, so I could get a feel for where my consumption is at within "daylight" vs the whole "day"

SunCalc is a good tool for this, if you're interested: https://github.com/mourner/suncalc

(I've used it on a personal project, and the API was a little awkward but the results are good: https://daylight.website/)

If you want to do some coding for your website, here is the ready-made javascript for calculating what you want about Sun and Moon: Sun and Moon almanac

tool: d3.js data: SunCalc the inspiration came from these sunrise and sunset visualizations

Recently I have made a library doing this for myself. Basicly, I re-wrote this Javascript library in C++ for use with microcontrollers: https://github.com/mourner/suncalc

you need a bit of IT skills wth https://github.com/mourner/suncalc

I ignore the sunrise/set properties of the Hue bridge. All the calculations are done on the board itself, so it doesn't need an internet connection to keep working. I used the javascript code here https://github.com/mourner/suncalc as a starting point and translated it to c++ to run on an microcontroller.

Suncalc [1] is the library I use to calculate the position of the sun. Mapzen [2] host public elevation tile data. This blog post [3] is a good overview of the calculations involved.
