We obtain the lightcone curvature and the expressions for the lightcone Frenet frame's vectors of a spacelike Smarandache curve of a. We prove that if the null straight line is the lightcone Smarandache curve of a, then a has non-zero constant lightcone curvature. Finally, we give some examples of lightcone Smarandache curves.eninfo:eu-repo/semantics/closedAccessSmarandache curves; Pseudosphere; Sabban frame; Geodesic curvature; Minkowski spaceArticle121819110.1080/1726037X.2014.922332WOS:000217637700008N/A
