Is the night time correct? For my location (Milton Keynes, UK) on 22nd July it says: 00:00 - n/a and n/a - 00:00 For 23rd July it says: 00:00-01:15 and 01:05-00:00 - so 1:15 hours and -1:05 hrs!?! - No night the day before? For 24th...

i want to build a roof which is cut out of a sphere that will block the sun for a certain period of the year. like say between april 15 to aug 15. i am in new delhi

I really like this - just what I need! Thank you. It would be great if the sun rise, set, arc indicator that overlays the map could be scalable to span greater distances. I'm plotting sunrise across Austin, vantage points to view sunrise/set...

To find the angle at which the sun's rays hit the land would help architects to make informed decisions.

There will be total solar eclipse in November 2012. Be nice to see the path of the umbra: http://eclipse.gsfc.nasa.gov/SEmono/TSE2012/TSE2012.html Awesome app!

it is a great idea to have a second overlay date on the map to compare to date sun angels that also shows on the map. So, a person can compare the seasonal effect on certain location. THANK YOU FOR YOUR EFFORT GOOD JOP

I would like to b able to see the suns trajectory from a side view. Not how it moves thru out the day but just a side view from ground level looking east or west. A splice of it so I can see how the sun is changing in angle as well as north and...

I cannot get the observatory exactly centered needs more resolution on decimal Latitude and Longitude (at least 5 significant figures after the decimal point keeps defaulting to county seat 50 miles away! Nice program. Just needs better LAT...

need hourly marks on your sun arc graph.... great job with this.

This would allow to quickly change the date and observe how the sun changes over the days & seasons

For each location, provide the longitude and latitude, Watts per M^2 per time of day per month along the min and max solar arcs, and solar irradiation level. This is an example of what I have in mind:...

When calculating available sunlight related to house structures the available angle of sun in relation to availability would be beneficial.

As an architect I'd love to be able to have a CAD version to enable me to add to my north point for my drawings. But have to say great site, just what I need - thanks.

Ability to provide/pass parameters to suncalc so that the map then displays a specific location. Currently it defaults to UK but we are in the US and would like the link to be dynamic so that depending on the location being viewed, suncalc will...

Local time- for example, if I am in India I would like to see the local time for sunset and sunrise, together with my location time (IP address time) this would help international users.

First of all, I would pay $0.99 or $9.99 for this app all day, everyday. Second of all, to provide more information to agricultural/ horticultural users could you add foot-candles to the 'sunrise', 'specific time' and 'sunset' readings? Any other...

Hi, I saw the sunset today Feb 9, 2013, and I used local landmarks to determine the true sunset line so I could compare it with this website. I noticed the true sun position was setting in a line exactly opposite the website's sunrise line...

Can you move the shading key from the top right of the screen to somewhere else? It covers the controls for the map (to get terrain etc) so its difficult to change the map view. Otherwise good app.

When you look at small black circle and red line, can it extend far enough to represent the distance needed to see unobstructed view. That way you can plan a great spot to watch sunrise or sunset. Maybe this is already represented here? :-) Great...

When shifting to ground view, it could be useful to have an image of the sun as you scan around. Moves with time tab as well.

Pretend you have a "SunEye camera on the roof of the building. Project the angle on the horizon of the low and high point for any day chosen as though you were viewing from that location. Would Google Street view be useful for that even if only...

South Launceston TAS 7249, Australia. 07 Mar, 2013. Sun path is reversed.

I found them in my basement; they're about 30 years old. Stumped in Niagara Falls NY. Can I use your system to solve this?

How can we save locations similar to Google Earth place marker?
