Dear colleagues, We performed the period analysis using the data observed from JD 2451700 to 2451710 by VSNET collaboration team. The calculated period is 0.17062 (11) d (sample number = 2343). The ten days averaged light curve shows a flat peak and a flat bottom. The flat bottom feature is also seen the light curve during JD2451690 - 2451700, but the profile around peak changed. The amplitude of the humps does not change from the previous one (about 0.08 mag). We had a tonight run on XTE J1118+480 from 11:00 to 16:00 (UT). Although it is rain season in Japan, the tonight sky is very good. Regards, Makoto Uemura on behalf of VSNET XTE J1118+480 collaboration team
