Hi All,

I'm merging this topic into the "I think I've found a track. What do you think?" thread.

2301802V1

Post by poohbahbah »

I just hit 2301802V1 as a possible track. Then I went to my events to see if anyone else had the same identification. It was 16 to 1. Now, usually, when this occurs, I look at the slide again and can ascertain why I am wrong. 2301802V1 has me puzzled. I identify a rather large possible track on the lower left side. Could someone tell me why I am wrong in identifying this area with a possible track. Thanks, poohbahbah

poohbahbah,

It is not that you are wrong in determining this as a possible track it's just your interpretation of the scan. Personally I would not have clicked it as a track as there is no surface feature to accompany the object that you have identified. After all if it was a track then the particle that creates the track must enter the aerogel at the surface and leave some kind of hole-like feature which is in focus at the surface.

Good luck with your dusting.

Hi poohbahbah,

You are not wrong to click movie 2301802V1 down in the bottom left corner. No one knows for sure what a real interstellar dust track looks like so we do the best we can. If you think you see what looks like a track then please click on it. Others may not think it looks like a track and will not click on it. I think it may be worth clicking on.

imho just some shade/out of focus effect from "dust" on the surface

Agree with Wolter: Out of focus

possible track

Post by Klemek »

Hi guys, wht do you think of that?
http://stardustathome.ssl.berkeley.edu/ ... =6065723V1

Only 2 out of 8 people clicked on it, but I think, that feature located in bottom left corner looks interesting. Any thoughts, comments?

Looks like a good candidate for a high angle particle to me.

Do you think there is a track at 75,239 for Movie 5197252V1? http://stardustathome.ssl.berkeley.edu/ ... =5197252V1

I see what you mean - very subtle - and very difficult to tell whether it's part of the other gunge around there or something independent.

In contrast, but certainly more in hope than conviction, I've just clicked on one of these two (?3) more obvious features in 4381183V1 (being 4th of 9; not posted before as far as know). They start as surface blurs then resolve into very well-defined circles. True, they then dissolve uncomfortably rapidly, but I'm reminded of the sudden 'terminal flare' characteristic of many small calibration tracks which also rarely persist throughout all focus levels.

OK: most likely debris /inclusions plus optical artefacts, and yes (so we're told) it's unlikely to find more than one particle impact so close together.
Still dusting in hope.

Track?

Focus slowly and look top right. Circle goes up and down.
