Han (CHO) report on behalf of the SVOM Multi Messenger Astronomy and GWAC teams (http://www.svom.fr/en/svom-mma-and-gwac-team): We observed the LIGO/Virgo trigger S200208q (GCN #27014) with C-GFT (Chinese Ground Follow-up Telescope in SVOM mission). C-GFT is located at Jilin, Changchun Observatory, National Astronomical Observatories, CAS. It has FOV of 1.35 X 1.35 deg**2 with a 4k*4k CMOS detector mounted on the primary focus of 1.2-meter-aperure telescope. The first unfiltered image was taken ~23.4 hours after the event trigger time. No credible new source was detected in our pipeline. A total number of 16 fields was observed. The coordinates (J2000) of the fields, the observation time, limit mag (5sigma), are listed below.
