Are you looking at the dot on the right half?

Try focusing about 90% down at look at the dot 150 microns from the left side.

If you refer to the little black point little center-right, I like it.

Arn't we looking for tracks ? I was under the impression the dust was not visible in these movies and would require higher magnification ?

Alex41, I looked closer and still think it is something on the surface, which is very uneven on this slide. To me this feature looks like in a valley surrounded by gel hills from west and east and a plateau continuing to the east. The fact that there are so many other objects are coming into focus with that feature also makes me think it is not the track.

Not by any stretch of the imagination.

The particle comes into focus 6 or 7 focus bars below every other item on the surface, which places it 18 to 20 microns below the surface.

All other surface elements come into focus at the same time, indicating that the surface here is quite flat with no slant and no bumps.

The length of the trail suggests this is not a high speed particle, but it is a fairly big one.

Any opinion on this guy? Is it just a cloud in aerogel?

Your image broke, but the link to the movie works.

I'm seeing three different faint events that shrink the deeper you focus, while all the surface clutter is growing.
So it seems like more of the "inclusion" stuff to me. And we still have no definitive answer on the inclusions, so its up in the air.

it's bottom right corner about 50 microns from both top and right edges. It's a faint doughnut appearing when you focus all way down. Is it what you were talking about, icebike?

Yes.

Actually I saw that one and others. These shrink as you get to the last bar of the focus, which says to me that they MAY be a track, or they may be one of those particles but we can't focus deep enough to resolve it. There is another one that almost resolves to a point at the deepest focus southwest of the big group in the middle.
