The annual Perseid meteor shower occurs when debris from Comet Swift-Tuttle intercepts the Earth at a high velocity (59 km/s, 133,000 mph). This debris is somewhat diffuse, so we see activity for many days on either side of the peak. Like most meteor showers, this is named for the constellation its members appear to originate in: Perseus.
This is a composite image of 300 meteors collected over three evenings from sunset on August 11 to sunrise on August 14. Since the images were collected over many hours, the radiant of the shower is not in a fixed location. However, because most of the meteors occurred between 1 am and 5 am, and because the radiant's high declination means it doesn't move fast, most of the meteors appear to point back to the same general area of the sky - just above the left center of the image. Note also that meteors farther from the radiant tend to make longer trails, since they have a smaller component of their velocity towards the camera.
Most of the meteors in this image are Perseids, but several other showers are also active (Alpha Capricornids, Southern Delta Aquarids, Kappa Cygnids), and those have not been removed from the composite.
The southwest monsoon pattern is currently very active, resulting in low transparency and occasional overnight clouds. This was exacerbated by a full Moon. As a result, many fainter meteors were missed. The Moon has been digitally removed from the composite image.
