Daytime Shadows

The animation below shows how shadows change during the day in the northern hemisphere. Shadows are created when an object, such as the stick below, blocks out some of the Sun's light. The length of the resulting shadow depends on how low or high the Sun is in the sky.

Try moving your mouse pointer over the time symbols to pause the animation at that particular time.

Interactive flash animation to show how shadows change during the day.

Here's a practical suggestion:

The next time it's a sunny day, go outside and have a good look at your own shadow. If it's midday then you will cast a shorter shadow than if it's late afternoon or early morning - just like in the above animation.


Please note that over the weekend of the 26-29th May 2017 we will be switching over to our brand new website - during this time there may be periods where the site is difficult to access, and users will be unable to request observations from the telescope. Please bear with us during this time. All should be back up and running by the 30th May 2017.
