Another Night of Aurora in Arizona

10pm to 4am in 15 minute increments

Uploaded 11/13/04

 Here is another automated sequence, with the Aurora Cam the next night after the big November 9th display, while the Kp index was at 5.0 and going down. Started later at 10pm, this sequence shows the first row is considerably redder than the rest of the images (frame 22 is the neighbors light) and clearly shows that while a Kp of 5 is normally not visible as an Auroral glow, it can be seen when it is coming down from a much higher value, such as the night before at 8.

Clouds can be seen rolling in at frame 15, and persisting for an hour or so, each frame is 15 minutes apart.

Enlargements from selected frames 0a and 12a for comparison, when the sky was nearly back to normal greyish.
