Tracking Changes in Photoperiod Around the Globe

Mystery Class Begins on Monday, February 10th.

Monday, February 10th is the first day of the Mystery Class project. Remember to check your sunrise/sunset times for your hometown.

On Friday, February 14th you'll receive sunrise & sunset data from the 10 mystery locations who are hiding around the globe. Over the next eleven weeks you'll be asked to unlock the secret of their location.

Remember to set your alarm clock! (Or, get a copy of your local newspaper where local sunrise and sunset data are provided.)
