Sensor dust on moon shots? (Page 5): Yes, I have read this, but still cannot understand how the meteor could burn if there is no atmosphere.

Burning is not the correct word. The meteor strikes the moon at a very high velocity. The sudden impact releases a lot of kinetic energy which affects the meteor and the moon rock to melt and some to vaporize. Plus some to be scattered. The amount of released energy can be huge depending upon speed and mass.

I might be the only one to capture a half dozen meteors hitting the moon at the same time. This would explain the bright spots on my photo. LOL

Some reported seeing streaks of light, just like a shooting star. That really made me wonder..how come when there is no atmosphere?
I just don’t know..LOL

I read the article and saw no mention of streaks of light. Only a tiny spot that flashed. It was photographed by many.

The OP's white spots are in very different locations, but, YEAH! let's go with a meteors!!! It is a way better story!

I read many articles. In one of them some eyewitnesses claim they saw streaking light. That was what made me wonder.
The OP was not referring to this but to the bright spots on the face of the moon.f

This link has a video showing the short flash. No mention of how the video was captured. I assume that it was time interval recording with no mention of how long the shutter time was or time between exposures. And no mention of additional streaks.

One more link with the meteor hit:

I also like how precise they were with this event!!!

See universetoday.com and they explain where the flash came from.

Interesting site. Didn't know about this site. Here is the link I found which shows the flash, but no mention of streaks. But they did have a gif file that tried to show how the meteor approached.

Also said that they were going to inspect the point of impact with the orbiter when it next passes over that spot.

They did mention that they first thought it was a hot pixel. But it did spill over into neighboring pixels that ruled this out.

Sunlight reflecting off a moving object? The moon was on the opposite side of the earth from the Sun.

Could be stars. At the exposure required for the blood moon, bright stars were visible.

Could be hot pixels. Have you done a hot pixel map?

They are too small to be dust, which would also show up as dark spots.

Could be hot pixels. Have you done a hot pixel map? <-- correct answer. Don't know if O.P.'s camera can remap stuck pixels.

They are too small to be dust, which would also show up as dark spots. <-- Yes, dust would show up as dark spots and would be much bigger.

Take another shot with the same exposure settings (longer time if need be) with the lens cap on. See if the spots appear again. If so, are they in the same position? If yes, you've got hot pixels in your sensor. Nothing to do but clone them out in post.
