Calculate sunset/rise anywhere in the world

Discussion in 'Leica and Rangefinders' started by patricks, May 28, 2002.

  1. OK, this might be old news to many but I just found this link to a site that allows you to calculate the local sunset/rise
    click here
     
  2. I got eroneous results. It's hard to believe that the sun didn't rise this month until after 1pm. It's usually up by 6:30am. I might have entered data incorrectly, though. I'll give it another check. Below is what I got the first time:
    Sunrise/Sunset Results
    Anchorage International Airport (ANC flight&FBO data aerial
    photographs CAP aerial photographs street map)
    Anchorage, AK (Anchorage Borough)
    N61deg 10' 28" W149deg 59' 46"
    US/ALASKA (GMT-0)
    We couldn't find ANC as an 'Airport Name'
    but found it as an 'Airport ID'

  3. Doh! It's not Alaska Standard Time, it's GMT! But it knows the
    time zone, why can't it display the data in local time?

    seems OK to me
     
  5. I did the computation again for my area with correct results. This
    time, I left the time zone setting on "Automatic." Last time, I
    provided "US/Alaska."
     
  6. totally understand. I probably would have messed that up if you
    hadn't point it out... :)

    cheers,
     
  7. Pat, great link! now I'll put it to use. Good to hear from you again.
    The camera and lens you sold me is excellent, if Pat has anything for
    sale don't hesitate; he's a good honest guy!!!!
     
  8. Another site with a similar tool is the U.S. Naval Observatory. This one doesn't require a nearby airport, and will also calculate moonrise/set, too. (Important for Noctilux users, I'm sure. ;-) )
     
  9. I don`t do the leg work myself. I got a very handy and correct
    laminated card in my bag; Sunrise compass bearing on one side,
    Sunset on the other. Index card size.

    I usually use sunrisesunset.com. The monthly calendar printouts (under
    'custom' option) are very useful for travel.
