CCD observations of 6 neglected RRab stars were taken at my private observatory over several years. Because of this long time span a revision of the elements of these stars was made. I derived the new elements of CG Lyr, KM Cep, V1369 Cyg, FI And, V633 Her, and CN Cam as: Star Max period ± JD [d] [d] CG Lyr 2455074.375 0.5089576 0.0000003 KM Cep 2455854.2925 0.56797305 0.00000003 V1369 Cyg 2455856.2946 0.56546555 0.00000002 FI And 2455849.46 0.5648195 0.0000001 V633 Her 2454387.3324 0.4899929 0.00000002 CN Cam 2455636.3228 0.6214465 0.0000003
