    This makes sense of a 'discovery' I made last solstice: I was checking sunrise/sunset times on a website that also features twilight times and I noticed where I live has night in midsummer, but another place I'd checked didn't, so I checked more and more places in between until I found where this line passes, within walking distance of my house. Forgot all about it, but now, knowing that 18° below the horizon is the cut-off point, it makes sense that it's exactly 18° south of the arctic circle (48°34'N).

    As an amateur astronomer, the situation with the astronomical twilight is not as bad depending on viewpoint. Until the sun is 14-15 degree below the horizon the light pollution is still brighter than the twilight, until then I can still take broadband pictures of deepsky objects like galaxies. For small band images like nebulae I have time until the sun is 12 degree below the horizon. End of June I have a small window between 0h30-2h45 local time. This is when I can take images of the Triffid Nebula (M20) and the Lagoon Nebula (M8) which reaches only 14 degree high in my area (which is in Belgium at 50°54' North) , and the small band nature of the objects gives me a little more room to capture the objects.

    I take exception to one thing said, that there are entire seasons in which UK does not experience "night", and only in the autumn does true "night" return. The problem is... the seasons run from solstice to equinox or equinox to solstice. Therefore, when summer starts (at the solstice), the cycle of no true night is already halfway finished, and is completely finished well before autumn starts at the equinox.
    Just sayin'....

    In Saint Petersburg in Russia during mid June to mid July we have what we call "white nights". It's bright as day even at midnight and it's hard to keep track of time

    What type of horizon? Local, geographic or sea level?

  • @bensmith2951
    @bensmith2951 3 года назад +1

    Civil Twilight - between 0 and 6 degrees below the horizon (when there is still enough natural light in sky to do outdoor activities without having to use an artificial light, hence it’s called civil twilight)
    Nautical Twilight - between 6 and 12 degrees below the horizon (when sailors can navigate the sea on a boat, hence it’s called nautical Twilight)
    Astronomical Twilight - between 12 and 18 degrees below the horizon (it’s still a little to see far away objects like nebulae and galaxies hence it’s called astronomical twilight)
    Emerald Campus Twilight - between 18 and 24 degrees below the horizon (when the sky is still somewhat light that you can still see a little bit of light but extremely limited, and can see like buildings still, hence it’s called Emerald Campus twilight)

    A little late and off topic, but even the International Space Station has times where it is in nearly constant daylight or darkness for days. It causes serious power management problems for the solar powered station.

    Well apart from not knowing that there was an official definition of night, I knew about the three twilights. I'm not convinced though that it's not night when it's astronomical twilight; is that really lain down somewhere?

      New England isn't but Angle Township in Minnesota is. Also, Bellingham WA also experiences nearly two weeks without true night at the height of Summer and is part of the Contiguous US. So Tom's more than a bit wrong even discounting Alaska. Informative video beyond that though.

  • @bensmith2951
    @bensmith2951 3 года назад

    Detroit barely stretches into that definition where Emerald Campus Twilight can last nearly all night from astronomical dusk to astronomical dawn, latitudes between 42.561 and 48.561 degrees north or south latitude will experience Emerald Campus Twilight for the rest of the night, I live close to the 40th parallel so are night only lasts for 2.5 hours, really almost 5 hours
    However latitudes > than 89.44 degrees, or within a half of a degree of either pole never experience nighttime instead their minimum on winter solstice is Emerald Campus Twilight
