The satellite images are acquired within 2 hours of solar noon to avoid extended shadows in the image.

7AM : early morning, low angle sun casts a long shadow.
9AM: mid morning, as the sun gets higher, shadows get shorter.
11AM & 1PM: around noon, sun is almost at its highest, so shadows at their shortest.

The shadows in a satellite images at times, obscure objects that makes it difficult to identify. On the other hand, the shadow cast by an object may be key to the identity of another object. Take for example the Washington Monument. When viewing from the aerial perspective makes it difficult to tell the shape of the monument, but with a shadow, it becomes much easier to identify it.

Considering these mentioned aspect of how a shadow plays a role in a satellite photo, this next set of missions focuses on:


Mission #19 – 27:

Thursday, March 22, 2012 – Friday, March 30, 2012


Dramatize and manipulate shadows by using temporal structures.
Think about how you can cause a shadow glitch by creating fake multiple shadows on ground (last week’s satellite photo manipulation method) Create a shadow narrative in the location of your choice. Check the aerial view of the location you will participate first by using the satellite map, and avoid shadows!

Time: Duration of the time when a satellite you chose is passing.



Don’t forget to document the scene (via image and/or video) that shows your attempt in making your mark and submit your documentation by using any of the following methods:

- tweet the image and/or video with the hashtag #bemysatellite or @_bemysatellite
- post the image and/or video on the BeMySatellite Facebook page
- email the image and/or video to


With the following information attached:

1. address of the location
2. mission number with time
3. your name
4. short description of your motivation for doing this (optional)


Good Luck!


Submitted documentation will post at the end of each week.
