2005 Orionid Shower

2005 OrionidsThe annual Orionid meteor shower occurs when debris from Comet Halley intercepts the Earth at a high velocity. This debris stream is somewhat diffuse, so we see activity for several days on either side of the peak.

This is a composite image of 70 meteors collected on the evening of October 19-20. Because the images were collected over many hours, the radiant of the shower is not clearly seen.

Long necklace-like streaks are stars or planets captured as they traveled across the sky over many hours. These form arcs centered on Polaris, which is located fairly low in the sky above the zero degree azimuth marker. The Moon was nearly full, and is seen as a bright arc. The dimmer arc facing it is the Moon's reflection inside the acrylic dome that protects the camera.
