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

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'

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

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."

-- Tony Rowlett (rowlett@mail.com), May 28, 2002.

totally understand. I probably would have messed that up if you hadn't point it out... :-)

cheers,

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!!!!

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. ;-) )

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. Available from FotoSharp, 17650 1st Ave S no 521, Seattle WA 98148. ph 800 361-8341

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