Sighting Report
Occurred : 8/13/2013 02:30 (Entered as : 08/13/13 2:30)
Reported: 8/13/2013 1:13:45 AM 01:13
Posted: 8/30/2013
Location: McHenry, IL
Shape: Unknown
Duration:~1 minute
Pulses of steady white light, 10 seconds apart, 10-15 degrees covered in 1 minute.

Light: As I was looking toward Perseus for some comet debris action, I noticed a pulse of light near Capella. The pulses of white light continued steadily, occuring every 10 seconds. They weren't quick, like the flashes of light on any aircraft I've before seen. They gradually gained luminance and dissipated at the same rate, spanning about one second. After 6 pulses, I saw no more flashes. The last two were not as bright as the first four.

Movement: The object moved in (presumably, because I could see nothing besides the light pulses) a straight path due East. It started at about level with Capella, just a few degrees to the left of it. Its path went a few degrees under the star, and 5-10 degrees to the right and 3-5 degrees below it, the pulses faded.

I heard no sound. It seemed very, very far up...but I'll leave the speculation up to you.

Apologies for approximations in measurements. I only have my hands to measure for the time being.

Thanks for your time!
