I guess we've ruled out atmospheric effects and window glass as the cause. Where are Barry & Noemi when you need them, anyway?

Sounds like a hippie thing to do. I hear that, if you whirl that wine glass around a nearby light and then stop it, it takes several orbits for the
detached trailing after-images to catch up and recombine. Don't try this at home. Is it true that Roy Rogers restaurants stopped wishing departing customers "
Happy Trails" because it
triggered
flashbacks?
BTW, the APOD footer has undergone some distortion of its own (which will hopefully be corrected at some point and orphan this comment). The
< and

APOD 090823 should point at
APOD 090822 and
APOD 090824, respectively, but instead they point at
APOD 090823 and
APOD 090825 - I momentarily thought I had lost my ability to click.
