We report on new estimates of the modulation expected in semiconductordetectors due to eclipsing of dark matter particles in the Earth. We reevaluatethe theoretical modulation significances and discuss the differences found withprevious calculations. We find that a significantly larger statistics thanpreviously estimated is needed to achieve the same level of sensitivity in themodulated signal.Comment: One change of author and minor revisions to match published version in Phys.
