    When I landed on Arkadia two weeks ago, I was surprised to see that the days were much longer than on Calypso, where the day-and-night cycles are just 2 hours long.


    So I decided to study the local sun, as I don't like to hunt when it's night. :)


    Here is the result of the study:
    - On Arkadia, the day-and-night cycles are exactly 9 hours long.
    - Because 24h can't be divided by 9h, the cycles don't start at same time everyday.
    - It takes 3 days and 8 cycles to retrieve the same hours (8 x 9h = 72h = 3 x 24h).
    - The sun appears on NE corner and disappears on SW corner. (+/- 2°)
    - On a given position, the sun is visible during 7h35, and unvisible during 1h25.
    - After the sun disappears, there are still reflects on armor & water, and shadows during 20 minutes.
    - When the sun reappears, the reflects on water & armors come first, then then shadows (very hard to notice), and finally the real colors start to replace the grey levels very slowly, depending on the landscape.

    09:05        7h35        16:40        1h25
    18:05        7h35        01:40        1h25
    03:05        7h35        10:40        1h25
    12:05        7h35        19:40        1h25
    21:05        7h35        04:40        1h25
    06:05        7h35        13:40        1h25
    15:05        7h35        22:40        1h25
    
    * Notes:
    - The times are in MA times. They are based on a central position.
    - If you are on east servers, these cycles will appear up to 25 min earlier.
    - If you are on west servers, these cycles will appear up to 25 min later.


    Other observations:
    - There is a 50 min gap between the NE corner (32777 x 32777) and the SW corner (8183 x 8133), meaning that when the sun appears on NE corner at time T, it appears on SW corner at time T + 50 min. Observations performed at altitude 1000 m to avoid the moutains and fog issues.
    - It means that during 35 min it's impossible to see the sun anywhere on the planet (1h25 - 50 min).
    - I tried to study the position of the sun in the sky at a given moment and found irregularities: it seems the sun has same position in the 3 right servers, another position for the 3 central servers and a third position for the 3 left servers. Desopte trying to teleport quickly, my observations my be incorrect. Maybe a team of 9 people reporting the sun position at an exact same moment would be the solution...

    Those are some pretty neat observations, Supertramp. I knew the day/night cycles extended for some time, but not for a full nine hours. Great work.

    Thanks for the info! I've been meaning to research this but never got around to it. Personally i wish nighttime lasted a little longer because it's hard for LBML to scan claims in the arctic (background it too light). But overall, i think the A-team has found a good balance with the current day/night cycle and darkness level.

    I love it, my inner nerd was glued to your stats! Good work, and thanks for sharing! I was very curious in how the cycle worked, as I also prefer to avoid hunting at night. :)

    I think they said they changed the cycle times since this thread was started.
