My neighbor and self-educated space exploration authority, Paul Gilster, wrote a blog entry today about the Perseids meteor shower, which reaches its peek on the evening of August 12. Debris from the comet Swift-Tuttle, Perseids gets its name from its origin — from our visual perspective — the constellation Perseus.

Even though this is a fairly prominent meteor shower, there has never been a spatial analysis of the Perseid meteor stream, according to Chris Crawford. He (she) asks, via his e-mail to Gilster,

what if we had hundreds or thousands of people all over North America and Europe observing Perseids and somebody collected and collated all their observations? This is crowd-sourcing applied to meteor astronomy.

Apparently a person with a fairly eclectic set of interests, Crawford has developed software that can be downloaded from his project web site. He asks that people download the program to their laptops and then carry them out Wednesday and Thursday nights (Aug 11-12) and watch for meteors.  As one comes into view, we click the mouse button on our computers.  The software records the time of the event into a log file.  Afterward, we enter our latitude and longitude into the program and then send off the file.

Presumably, the data will be used to assemble a three dimensional map of the debris stream.  Gilster closes his entry with…

Usually I write about celestial debris in the context of the clues it can offer up to astrobiology, or as examples of the need to develop the technologies to fend off larger objects like asteroids. But a fascinating outgrowth of our ever more powerful desktop technologies is the ability to put in just a small amount of time to achieve a widely distributed result, one that looks at a natural phenomenon in a new way. Here’s to the success of the Perseid Project, with the hope that it’s a forerunner of future skywatch collaborations.

    The original CPC was so easy to use; I could observe objects with the whole family. Set-up was easy; it found every object I wanted to observe. But the corrector plate on the unit I owned had obvious flaws (streaks, bubbles, spider web-like structures); I returned the product. I am waiting for Celestron to release a CPC with the new Edge HD design.
