A little online application with interactive map that shows sun movement and sunlight phases (with dawn, sunrise, sunset and dusk times) during the given day at the given location.
As i use the slider, and the direction of sun changes, can i get direction (in degrees) and elevation of the sun at that point (degrees above horizon)?
User selects the height of an object - maybe representing a tree or a building. SunCalc calculates the length of the shadow and displays it from the location (it would be the opposite of the orange sun position line). This would be extremely...
Currently SunCalc shows all times in the visitor's timezone. It would be great to make an option to display them in local timezone (tied to the current location).
Landscape features (such as mountains) can greatly affect sunrise/sunset time. Since Google does provide elevation information, it makes sense to use it to adjust sunrise/sunset time (and even sunrise/sunset location a little bit when it touches...
Add degrees that sun is above horizon at time of day on arch. That way you can see if the sun is going to clear a hill or building at a certain time of day at a certain location. Add this to a degrees relative to magnetic north and, with a...
Create an icon of a man or any other commonly understood shape at the address or location of interest.
Create a shadow for the man and move the shadow depending on the sun angle.
As a homebuyer, i'm looking for good sunlight in a potential...
Buttons that, when clicked, would move the sunrise/sunset lines where they would be at equinox and the summer and winter solstice. That would avoid changing the calendar to know what's the sun path during the extremes of sunlight (winter and...
Sunrise and sunset can be affected by the presence of high mountains near our position. This can be solved using our X, Y, Z position and topographic relieve of the area which can alter the actual hours of sunrise or sunset.
Чтобы вот этот маркер (http://maps.gstatic.com/intl/en_ALL/mapfiles/marker.png) отбрасывал тень в зависимости от положения солнца. Мелочь, но очень приятная...
It takes a while to substract two time values to see, in example, the duration of daylight period, so it will be useful to show it somehow in detailed information box
Very useful for surfers etc. Also a boon for photographers and the like for capturing the right type of sunset shot !
A big " ask " I know, but would be an outstanding addition.
It would be good to see what is local time difference between selected center and other map points:
add inner circles with time gradations -5; -4; -3; -2; -1; 0; +1; +2; +3; +4; +5
Show the optimal direction for solar panels to point. I guess that would be solar noon ?
Also, I have IE 7 and the time slider is off the screen to the right.
Thanks
Philip
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?
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!
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.
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
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.
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?
Show a Solar Noon Line in the graphic. Could create a toggle button between "Now" and "Solar Noon" in order to not make the graphic too busy. A great application by the way. Love it!
It would be nice if the program would generate a nice report showing the sun location along with the time and date fthe specific time indicated and show the location entered by the user.
if you go back to the years 1950 til 1960 there was no daylight saving in Westeurope. I expect the same behaviour as for the years 1961 til 1979. So from 1950 til 1979 there was no daylight saving time.
I would love to see the ability to make a diagram of the sun movement over several days or weeks, not just one day. For example, I would like to track the sun movement over the growing season (May - Sept). Thanks!
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.
I use the tool to figure out where light will fall on an airplane while I am out spotting / photographing them. It helps visualize what time of day the sun will be on either side of a particular runway. Having the degrees indicated in the circle...
Corregir "salto" brusco (barra vertical inferior) al mediodia entre los días 27 y 28 de Marzo.
Correct "jump" sharp (lower vertical bar) for noon hour between 27 and 28 March.
I would like to see the sun line all the way to the edge of the map, even if I zoom in or move the view so the position marker is way outside the current view.
I think a good idea would be to add more details on the position of the sun. Able to issue a "langtag" (like google maps) with suitable tilt and azimuth of the sun.
The sun path could have marks delineating each hour for better visual comparison over time. Say you set the slider for 10:30 or so then you could visually estimate where for the preceding and next hour.
Where are sunrise times similar in the US? I would assume that two locations that are not necessarily close to each other could have the same sunrise, if one were southwest of the first. I would love to see this depicted in a map!
When I am sitting in the house facing parallel to the street, I would like to be able to rotate the map to orient and align the street to my position in the house. In this way, I can have a better perspective of Sun movement in different times of...
This idea will require the incorporation of objects that can cast shadows.
Sun calc would use the location information and projection of shadows to determine the intensity of solar radiation that reaches the ground over an entire summer growing...
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.
I love the functionality and design of the slider. But when I move it to either side of the Now, I'm never sure exactly where I'm setting it. "12:20ish" is the best I can do.
The thing about this tool is that it's actually ridiculously...
Allow users to specify which direction their roof faces to help calculate how long it is in direct sunlight to help with getting more detail as to how much solar energy they could produce in a day.
ie. If they're roof faces roughly NW and is only...
I'd like to suggest adding a marking that represents the visible distance to the horizon from the point of origin (assuming perfect weather conditions and an aproximated earth curvature). The purpose of this is to figure out at any given point,...
make it as if you are standing someplace and wish to track the sun from sunrise to sunset with location of the sunrise. This would allow us to see the angle of the sun in degrees to if you want.
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.
I'm not sure if it does it already, but adjust the calculation based on the height of the location above sea level. It might also be good to adjust the results based on a certain height above the ground too (so when will the sun set if I'm in a...
Hi Mourner,
I *love* this site/app and have wondered for some time how to see/get this information. I believe the only way it could be improved would be to add the historic temperature for the pin marker's location based on the date and time...
I am planning a vacation to Honolulu and would like to be there when the trajectoy is a streight line (sun sets due west). How do I set the location and determine the date?
Each time I go to use SunCalc, the date is 23 Oct 2011. Thus, when I click on the date box, I get the calendar for October 2011. How about putting the current date in the box? I realize you can click the NOW button, but it would be easier if...
Although I add my geocentric coordinates (http://suncalc.net/#/xx.xxxxxxx,-yy.yyyyyyy) to the initial SunCalc calling URL (where xx.xxxxxxx is my decimal latitude and where ,-yy.yyyyyyy is my decimal longitude) SunCalc ignores it and centers the...
Three major things:
1: 1 more scroll bar for date so that the sun path is updated while dragging the bar
2: location should be also chosen by longitude and latitude info (so that one can paste this info from google maps bookmarks)
3:sun angle...

Your program shows sunrise at three pm in the afternoon.
Obviously, your time zone database is incorrect.

When I put the balloon on the equator the lines showing the sunrise/sunset angles still go to the south. Even in the southern hemisphere they point south.
For a given location (Lat/Long) I would like to see what the daily maximum solar radition could be. I collect 10 minute interval solar radiation data in Wm2 at my weather site in Bristol, UK but I have know way of knowing whether my 6000 Wm2 for a...
