Busy and exciting times here, thus only irregular updates.

At times you find yourself in a situation where you need to know where the sun will be at a given time. It might be that you need to film a sunrise, simply to know when the light starts in an unknown location, or to calculate shadows.

On a Mac or Windows machine, there is a $87 program called SunPath, which holds information for about 40.000 locations world wide. If you have an internet connection, you can also go to Sunposition.info, which will draw a nice map of the sun’s position,  or use the Sun tools on timeanddate.com, which offers a variety of tools:

• Astronomical Twilight Starts/Ends
• Nautical Twilight Starts/Ends
• Civil Twilight Starts/Ends
• Sunrise and Sunset
• Sunrise and Sunset Azimuth
• Length of day
• Solar noon at time/altitude/distance
