I became fascinated with this subject after noticing some yellow/green artifact bands from some of my iPhone images of the eclipse (see my image in post #2). This led me to research this topic and I found that there really isn't a lot of info or images out there about the Lunar Total Eclipse 'Rainbow Moon' effect. Now, with a proliferation of modern cameras and telescopes aimed at the moon, we can get more photographic and visual data. I did find a few links and a very informative NASA video:
https://www.foxweath...l-lunar-eclipse Here's a quote from Seminole State College Astronomy Director Derek Demeter:
"Demeter says if you can look at the moon during the eclipse through a telescope, you might see more than red. "You can actually see on the very edges of the moon, a blue light, then an orange light, a yellow light. You see all the colors of a rainbow," he explains. "So really a total eclipse moon should be called a rainbow unicorn moon because, actually, you see all the colors of the rainbow, cast on the moon because a portion of the white light that is split into the colors of the rainbow can be seen on the moon.""

What causes a Rainbow Moon? It occurs when the moon just enters or starts to exit totality during a total lunar eclipse. The earth's atmosphere scatters light and casts a rainbow shadow onto the moon during these few minutes that the moon transitions through totality.
Disclaimer: I compiled these images from the web, and with permission, from some fellow CN members. The color saturation I used in GIMP may be considered pretty aggressive and may represent some false color enhanced from the original images' processing. I tried to use only enough saturation to show undeniably that there is a rainbow pattern eeked out from the original images' color profile.
To future rainbow moon observing!
