Have mirror micrometeorites been detected?

Slow-moving $(v\sim 15\mathrm{k}\mathrm{m}/\mathrm{s})$ “dark matter particles” have allegedly been discovered in a recent experiment. We explore the possibility that these slow moving dark matter particles are small mirror matter dust particles originating from our solar system. Ways of further testing our hypothesis, including the possibility of observing these dust particles in cryogenic detectors such as NAUTILUS, are also discussed.
