                         before the prospective occurrence of equatorial plasma bubble 
                         (EPB). We use the scanning mode observations made by the 30-MHz 
                         Gadanki Ionospheric Radar Interferometer for estimating 
                         interbubble spacing and high time resolution observations made by 
                         a collocated digisonde for inferring horizontal wavelength of 
                         wave-like variations prior to the onset of EPB. Horizontal 
                         wavelength of wave-like variations has been inferred from plasma 
                         density variations and height variations of isodensity contours; 
                         both show consistent results. Remarkable agreement has been found 
                         between the estimated horizontal wavelength and interbubble 
                         spacing, which demonstrates the potential of digisonde in 
                         providing relevant seed structure for a prospective EPB formation. 
                         Further analysis based on observational results and numerical 
                         simulation of collisional interchange instability shows that while 
                         the eventual formation of EPB has a strong bearing on the height 
                         of the F layer and density gradient scale length, the growth 
                         perspective of the EPB depends on the seed wavelength. These 
                         results are presented and discussed keeping the future prospective 
                         of EPB forecasting/nowcasting.",
