At home I have a nice view of the Fujisan to the south-west. I often take pictures of it in winter when the skies are so clear.
Many times I’ve told myself it would be nice to take a picture with the sun setting right behind the mountain. I’ve searched the internet for an app that would tell me when this happens but all I could find were apps that tell you where the sun sets on a particular day, not the other way around. So I decided to build it…
Sunsetter is a simple python web app running on Heroku. It’s based on the brilliant pysolar library for the hardcore astronomical calculations and binds it all to Google Maps with a dash of Ajax and JavaScript.
The app still needs polish but the data it gives out should be pretty accurate and reliable at normal altitudes (standing on top of a very tall mountain overlooking a wide plain will change the distance of the horizon and screw with the calculations a bit).
If this app was useful to you or you have suggestions, I’d love to hear from you in the comments.
Update (2012-06-03): I’ve open sourced the code on Github.
Nice! RT @w00kie: launching my latest pet project: Sunsetter – find when the sun sets over there http://t.co/zvDT7x3D
Cool Project Sunsetter by my friend @w00kie – “find when the sun sets over there” http://t.co/niO0SR72
it looks like a very cool project, unfortunately i am only getting an error message, what ever angle i try
Note: the app was returning an error last night. I believe I have fixed the issue (unexpected error on memcached failure) and it is now working again.
Hi, Thx for posting the app on github. I am having problems with runnung your app locally.
After making sure that I have all required tools installed I am starting the the app with foreman start -f Procfile.dev
I am getting the following error

By the way I am using a Mac. Any ideas?

Hello Roman,
I think you’re missing a virtual environment and the pre-requisites installation. I advise you to read this document first: https://devcenter.heroku.com/articles/python
Basically what you should do is first install the venv in the folder and activate it:
It should change your prompt confirming your are in the virtual environment and any library you install is done so locally instead of system-wide.
Then you can install the requirements with this command:
