An interesting interaction between equatorial plasma bubbles (EPBs), medium-scale traveling ionospheric disturbance (MSTID), and midnight brightness wave (MBW) were observed at Cachoeira Paulista, Brazil (22.7°S, 45.0°W, magnetic dip latitude ~20°S) by all-sky images of OI 630 nm emission, 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. The MBW was observed propagating to south-southwest. After interaction with MSTIDs, the EPBs tilted and became larger and narrower. This effect could be associated with the x drift and also with changes in the neutral wind. Furthermore, the MBW also interacted with EPB and filled the EPB edge with plasma.
