                         less explored with in situ experiments enabling to capture local 
                         fine structures. Here, we present the multifractal analysis of 
                         electron density fluctuations in the EF valley region, obtained 
                         from a rocket experiment performed at equatorial low lat- itude 
                         station, Alc{\^a}ntara, Brazil to explore scaling structures in 
                         the plasma irregularities. The multifractal spectrum is validated 
                         with a analytical model that mimics the energy distribution in a 
                         turbulent cascade using probabilistic weights. We report the 
                         nature of the EF valley region irregularities to be multifrac- 
                         tal, asymmetric, intermittent and nonhomogeneous. The multifractal 
                         measures show transition of the influence from smaller to larger 
                         fluctuations as the rocket approaches the F layer base, 
                         consolidating ear- lier observations. By identifying the nature of 
                         the irregularities, we explore the possible cause for a wide 
                         variation reported in the spectral indices. Our analysis 
                         demonstrates the usability of the multifractal ap- proach in 
                         studying the nonlinear fluctuations observed from the E-F valley 
                         region in situ data.",
