Abstract
Nuclearites and strange quark matters are hypothetical super-heavy exotic particles and may be important components of the dark matter in our Universe. They may have a typical velocity of about 220 km/s (galactic rotation speed), whereas interstellar meteoroids have geocentric velocities larger than 72 km/s corresponding to a sum of escape velocity from the solar system and the velocity of the earth around the Sun. We studied the possibility to search for such fast moving particles by using very high sensitivity CMOS cameras. We have observed many meteors using a stereo camera system at the Telescope Array UHECR experiment site in Utah and other places. We estimate the observable mass ranges for the moving nuclearites and the interstellar meteoroids using the observed meteor events. Observable flux limits are also estimated for these mass ranges. Future plans is also reported in this paper.
