Thanks for this Peregrinator, might be a nice one for those photographically minded people on here. Or for those who are just strange and like to be up early anyway :p

I use this one: http://www.timeanddate.com/worldclock/sunrise.html

Actually, I mainly use it to keep track of the moon (http://www.timeanddate.com/worldclock/moonrise.html)

I like it because when you chose "all columns" they have a whole lot of info about the angle of the sun / moon etc. So if you're planning to walk by the moon you can get an idea about where it's path will be, as well as how full it is. That can make a huge difference!

I use an app called Moon Deluxe

Had to turn the music and sfx off though!

Generally I just use Pocket Weather Australia on the iPhone.

For looking into the future and planning, I use The Photographer's Ephemeris.

There are many many alternate free options on those app stores. But for active use, these two apps really are excellent.

If you're just after the sunrise and sunset then you can simply Google search, "(Sunrise or Sunset), (location)" and Google will automatically tell you the time.

e.g. Sunset, Katoomba NSW

Of course the times vary a bit when you are in mountainous terrain!

Heavens Above is also a great website, especially for the appearance of the ISS, which the kids love as well as Iridium flares.

I just turn on my eTrex 30 and hit Sun and Moon.

I have this for my work. It helps to deduce overshadowing of buildings etc, but I know it's used by photographers.

The bloke is very amenable to discussion, suggestions.

You can shortcut by typing your postcode into willyweather. Sunset, moonrises and phases.
It also gives you weeks view scrolling through any day of the year.

Also apple app but no android yet.

You think we've been left in the dark? (sorry, couldn't resist)

I use a similar app that also works well. https://itunes.apple.com/au/app/sun-seeker-3d-augmented-reality/id330247123?mt=8

It really helped me get a good positon in Narooma for this shot a couple of weekends back. I got there quite early and managed to perch my tripod up on some rocks before other landscape paparazzi arrived.

A couple of other favourites from the same position:

I used to be able to calculate it based on graphs and lat/long when sitting navigation exams at uni.

Another one of those things you learn to do at uni and never, never use.

You just used it to brag. Definitely useful!

Was a nautical almanac cheating?

Whatever happened to extrapolating it from the time and angle the sun rose/set the day before?

Nothing happened to make this ineffective, other than the fact that I'm in Victoria planning a trip to the Vulkathunha - Gammon Ranges next year, so I won't be in situ on "the day before".

But your question does answer another question that may have arisen here in the absence of recent posts: whatever happened to north-north-west?

Geoscience Aus can be a hard website to navigate around.
Here is the link to the Geoscience Astronomical Information Page

Hope that's what you're looking for

Great, you'll love it, the Gammons are brilliant.
She'ds currently on a 10 week road trip (having already done Fliners/Gammons/Arkaroola and a whole lot else), having a short online break at Katherine before heading west for another whole lot of else.
Three and a bit weeks to go. How time does fly . . .

You're right about the Gammons. Next year's trip will be the fourth year in a row that I'll be going there (also Flinders Ranges). I'll be going at a slightly different time of the year, hence my need to know how many hours of daylight will be available.

Only a couple of the responses from others about the software they use for calculations refer to online sites. I can't comment on any of the apps mentioned because I don't have the hardware. The main advantage of Geoscience over the websites mentioned is that location choice is much wider.

I'm envious about your ten-week trip. I hope you're able to report on your walks here.
