The simultaneous observations of total electron content (TEC) and intensity of nightglow OI 630.0 nm emissions is used to examine the occurrence of equatorial plasma bubbles (EPB) in low-latitude night time ionosphere over India. The radio observations of TEC using the Global Positioning System (GPS) were carried out from Hyderabad (17.67?N, 83.32?E). The optical observations of nightglow OI 630.0 nm images have been carried out using all sky imager (ASI) from Kolhapur (16.8? N, 74.2? E) during April 2011. We have taken an average intensity of a square bin (5 ? 5 pixel) of an individual image (OI 630.0 nm) in order to study occurrence of EPBs. The zonal drift velocities of EPBs were estimated using method recently developed by Sharma et al. (2014). The EPBs occurred in evening hours ~19:30 IST and move towards eastward with average speed 138 m/s. prior to local midnight, and then gradually decreases with time. The calculated EPB velocities are compared with recently developed model by England and Immel (2012). We found that the time difference between occurrences of EPBs in TEC measurement and intensity of OI 630.0 nm about ~1 hr. Herein we have discussed possible mechanism for occurrence and evolution of EPBs over Indian region.
