Sighting Reports 2009 Infrared Video Detects Quick Flash in Sky
Date of Sighting: June 26, 2009 Description: Ali Nicholls and William Puckett set up two cameras oriented at angles of 30 degrees above the horizon and at an azimuth of 35 degrees. Footage was observed live from both cameras on TV sets and footage from each camera was recorded on DVD recorders. Footage above was collected by an IGEN infrared camera which is sensitive from wave lengths of 400 nanometers to 1,000 nanometers. (Visible light ranges from 400 to 700 nanometers while infrared starts at 700 nanometers.) The other camera was a FLIR Model B2 which is sensitive in the far (thermal) infrared from 6,500 nanometers to 13,000 nanometers. The FLIR camera did not pick up anything unusual. Many birds and insects were detected by both cameras. Several satellites (seven) were detected by the IGEN. The above flash happened twice and was first detected on the right and then to the left around 30 seconds later. Only one of the flashes (second) shows up on the video extracted from the DVD recording. It is my belief that this flash was the result of a bright iridium flare satellite. However, the website: http://heavens-above.com did not show any iridium flare satellites in the area at the time of the sighting. However, it is my understanding that some satellites may not be tracked on this website. Note: The remarks above suggest that the flash was probably an iridium flare satellite. However, this is speculation as available satellite charting did not show any iridium flare satellites in the area at the time of the sighting. |
