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. |

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 : ) |
