More Aurora Activity over

Payson, Arizona

Uploaded 7/23/04

 Caused by a opening in the corona on the sun a few days earlier, this faint aurora was not seen visually, but photographed with the red sensitive Supra 400 film, in a 4 hour sequence taken automatically with our robotic film camera, the Aurora Cam. Once again proving its worth at captureing even faint aurora in late hours of the night and early morning.

Please Click on Thumbnails below for larger images:

 This image was taken at about 9:30pm and shows a faint red auroral glow on the northern horizon, just under Ursa Major. This glow lasted about 30 minutes which was captured in the first three images, and was gone after that, corresponding well to the rapid fall off of the Kp index, which was 7 at the time. (The clouds can also be seen wisping through the image)

 20 minutes later, this image shows the glow gone, and a normal neutral grey sky to have returned to the north. All other images after this show no auroral glows. The clouds really started to move in at this point : )
