Occultations and transits are the two events popular in amateur astronomy that would benefit from timed observations. While it is possible to observe such occurrences by timing the start and the end of the event using a simple stopwatch, a better and certainly more accurate alternative would be to use a camera with a timer to time such events.

Fortunately, a simple setup for timing occultations and transits may be assembled using a telescope, an external video recorder, and a “hacked” point-and-shoot camera using CHDK, a free software that can greatly enhance the capabilities of a number of Canon PowerShot cameras.

The International Space Station (ISS) currently orbiting approximately 400 kilometers above the Earth’s surface will treat us with a spectacular sight on November 3, 2012, as it zooms past above the Philippines. The satellite will be visible to us because its solar panels will be geometrically well-placed to reflect sunlight towards the ground, acting like giant space mirrors. From the ground, it will look like a very bright flare coming from the northwestern horizon and then slowly (much like an airplane) move towards the southeastern horizon until it disappears from view. It will be visible for approximately 6 minutes, from 06:10:29 pm to 06:19:09 pm and will be visible to the naked eye. No special equipment is required to observe the satellite flyby. (Predictions updated as of 1 pm, November 3, 2012.)

Those with cameras and telephoto lenses may attempt to image the satellite and detect structure, similar to the photo below.

The main body and the solar panels of the satellite are visible in this photo. 4-in f/9 refractor, Canon 450D, ISO 1600, 1/100 sec exposure.  This is my second attempt in capturing the ISS.
