%X Observation of equatorial plasma bubbles (EPBs), mediumscale traveling ionospheric disturbance (MSTID), and midnight brightness wave (MBW) were made using the OI 630 nm emission by an All-Sky imager located at Cachoeira Paulista, Brazil (22.7◦S, 45.0◦W, magnetic dip latitude ∼20◦S, referring to 2015) on the night of September 17-18, 2015. The EPBs were observed moving eastward while the MSTID propagated northwestward with the wavefront aligned to southwest-northeast. On the other side, the MBW was observed moving to south-southwest. After the interaction between the MSTIDS and the EPBs, the latter became tilted, grew and narrowed. This effect could be associated to the ExB drift and also to changes in the neutral wind. Furthermore, an MBW also interacts with EPB and fills the EPB edge with plasma transforming it into a bright structure.
