Abstract: In this paper, the equatorial plasma bubbles (EPBs) of March 30^th, 2014 were studied using airglow images of 630 nm emission and observations of VHF radar over Hainan Fuke Station (19.5°N, 109.1°E) from the Meridian Project, digisonde over Hainan Sanya Station (18.4°N, 109.6°E), and data of C/NOFS. In this case, the morphological features and evolution processes in detail were analyzed. The results showed that there were a group of EPBs during the night. Nine EPBs were observed in this case. These EPBs occurred after sunset, lasting after midnight. The lifetime is about eight hours (from ~20: 15 LT to ~ 04: 15 LT). These EPBs moved from west to east during the night. Their longitudinal ranges are more than 1200 km. East-west ranges of EPB group are more than 2900 km. Besides, two EPBs (b5 and b6) showed a merging process. Portion of b6 merged into the b5 and then formed one EPB. When those plasma bubbles were observed by the all-sky imager, corresponding range spread F and plume irregularities also were simultaneously observed by the digisonde and VHF radar, respectively. Meanwhile, observation from C/NOFS also showed plasma depletion. Evolutions of these EPBs were simultaneously observed by optical equipment (all-sky imager) and radio equipment (VHF radar and digisonde) of ground-based measurements, and C/NOFS satellite.
