Meteor Camera Investigations





What is the Sierra College Meteor Camera?

This page contains recent video captures taken with the Sierra College Astronomy Dept., Sandia Fireball Network Camera. Click here for more details about the Network and participants METEORS!

The system is an “All Sky” video camera which has a 180 deg. field of view. There is a custom signal processor and memory system which buffers a few seconds of video. The processor compares each captured frame to the previous, and when it detects an event (meteor), the previous frames are sent to a host PC. Software in this system produces a "back in time" image and a video. These videos are xxx.mov files, and can be viewed with an Apple Quicktime plugin viewer. The images are black and white (some have been false colored [amber] to enhance contrast and event detections). The xxx.jpg images are composites of the entire video. Some of the detections also have an "autoexposure" which is a xxx.jpg stacking of 10 images to bring out the brighter stars. This allows for precise positioning of the event.

The camera is located on top of my house at 38 deg. 48’ 31” of latitude and 121 deg. 14’ 57” longitude and an elevation of 119 meters in Rocklin, CA (USA), about 20 miles northeast of Sacramento, CA. We are coordinating our observations with Wayne Watson in Nevada City and Larry Stange in Yuba City who are also operating Sandia Fireball Network Cameras.

A fireball (or bollide) is another name for a very bright meteor due to atmospheric entry of space debris, both natural and man-made. Our experience thus far shows that they occur about once a day, with a bright one every week or so. The cameras began regular operation around mid-April 2004. It is an automated system which operates from just before dusk to just after dawn. Some day time operations have been attempted, but so far only a few daytime fireball event have been captured.
