Some friends flew eastwards from New York to Singapore on a direct flight (it's one of the longest flights). I wondered what their experience of sunrises and sunsets were (they departed 10PM), I've noted down the times but haven't plotted it...

Later this year I'm flying from Europe to the West Coast of Canada, and it seems I'll be in daylight for the entirity of the flight (departing 2PM local, landing 4PM local after a 10 hour flight).

Edit: well, FR24 has a handy flight tracking that includes the daylight progression: https://www.flightradar24.com/data/flights/sq23#3de5a306

So they flew 18 hours and experienced a full daylight cycle, arriving just before the second sunrise...

Neat. Similar to https://www.suncalc.org, which also lets you zoom to the neighborhood level. Very useful to figure out when/where sunlight will hit your house.

This is great for photographers planning golden hour shoots. The neighborhood-level zoom is particularly useful.

This is a cool visualization. I wonder if it uses the excellent solpos.c library from NREL as the core engine?

I recommend activating "Show Illuminating Sun Beam" under "Explanatory tools" by clicking the graduation cap icon in the top right corner.

Love it. Needs a moon.

This is incredibly cool!

I've been wanting to make a little circadian rhythm graphic based on the sun, would love to have a graphic like this to support it. If Andrew Marsh is listening, would love to create something to extend what I have (Preview at sun-taupe.vercel.app)
