Aurorae occur on other planets with magnetic fields. Jupiter's have been photographed!

The green oval and its dot show the position of Io and its effect ("flux tube": current of charged particles)
on Jupiter's aurorae.
AARRRGGGHHH!!! I was MONITORING my STD Aurora Monitor program and Spaceweather both!
This was unexpected, and I MISSED IT!
DANG! It's beautiful, though.
Did anyone see it? Get photos?
Get on the APOD PING list!

Still too light here to see much aurora. The red aurora is rare, but there was a huge red aurora when the first Space Shuttle was launched. The green rays are common, and when they are bright and focused they also move rapidly like a flapping curtain or swirl across the sky, often with other colors in the most intense portions.

The active link "other streams" in the above official explanation discusses anti-auroras.
In your humble, but always correct opinion, are the dark "pickets" between the "green pickets" anti-auroras?
If so, then the "picket fence" appearance is more likely due to the effect of the Earth's Magnetic field upon the incoming solar wind, rather than discrete pulses from the Sun.
