This is the track of a 0.4µm othropyroxene grain fired into flight spare aerogel at 15 km/sec at the Heidelberg van der Graaf dust accelerator. The is the best laboratory analog to an interstellar dust track produced to date.
Although you can find the tracks easily, computers are not very good at this kind of project. This is why we need you.
Remember: to identify a track be sure to click on the deepest part of it that you can see, even if it is out of focus.
