UV index value updating as the sun moves

I would be cool to have a UV index value being updated as I move the specified current position line of the sun (if possible at all). Thanks much!!

Allow users to make a perma-link to a lat/lon

I would like to be able to make a perma-link to a lat/lon so I can bookmark the sunrise/sunset. Ideally the perma-link would not include the time, so the link would show the sunrise for the current time.

Make it work for arctic/antarctic zones

in polar circles, SunCal displays a lot of (very understandable) "n/a" I would like it to show the date+tiem of the previous/next sunset/sunrise as well as the duration of the polar day/night. I know it's hard, few ephemerids do it...

Select first an observer point, then a second poin

Select an observer point, then a second point, and get time and date when segment joining both points is parallel with sun direction.

I thought about that from the start, but this involves quite complicated Math and I didn't yet find formulas for it. If I do, it will be implemented for sure!

Have like a POLE that reproduce the SHADOW.

Drop a POLE and reproduce the SHADOW of the POLE, showing direction. Even more can show the aprox RATIO for the shadow and the HEIGHT of the POLE.

moving the sun and the app saying the time

Doesn´t seem very useful but... what if the sun is not where you want that day? You can tell the app where you want the sun and it responds: "Wait till 14 of May" for example, or "Not posible, think about another photo". With this you...

Actually this is a nice idea, especially for sunrise/sunset directions (would be cool if you could drag the path and it would change the date immediately). I thought about this but unfortunately I didn't find the Math for such calculations, need some help from a good astronomer.

turn the whole plan to viewdirection of a photo

I would like to turn the whole plan with all information to a given direction of a photo. I know nearly, from which point a photo was shot, I see i.e. a church tower on the photo and on the plan. So I want to turn the plan, to be more precise

Elevation information

I understand that getting the elevation data out of Google maps or Google earth is probably not feasible, but adding for the elevation layer in addition to the "map" and satellite" view would be a good start.

Continue to show the direction of the sun at night

Continue to show the direction of the sun at night - perhaps using a thinner line or different colour. It is interesting, in winter at least, to be able to see the sun approaching dawn.

Zoom out, a link covers the "-" button

At the right bottom a weather forecast link covers the "-" option in the zoom bar. I cannot remove this little window, so I can only zoom in.

add equation of time, solar noon (official hour), declination

Great for sundial design! Add some calculates about equation of time (value and annual graph), solar noon, declination, azimuth and elevation, in 3D view some annalema representation.

Mourner, 09.04.2010
Thanks for the suggestions! I know how to calculate these values but could you please explain what's the practical use of equation of time and declination values?

sum up solar energy over growing season

As a photographer, I like to know the position of the planets and constellations at dusk and dawn. They make great background for landscape photography.

Время отображается ваше текущее, а не время выбранного места, но я работаю над фичей переключения на локальное время. :) Насчёт тени - хорошее предложение, может, поделитесь примерным представлением о том, как это должно функционально выглядеть? проекция траектории одной точки в зависимости от заданной высоты?
