		<abstract>The ionospheric irregularities associated with spread F were first observed from the rocket flights 40 years ago. Such in-situ measurements provides useful information regarding the development of plasma depletions or bubbles and subsequent generation of small scale irregularities. These measurements have been used to obtain the power spectrum of fluctuations associated with the equatorial spread F. An equatorial station Alcantara (2.31oS, 44.4oW) in Brazil has a rocket launching facility. From this station, rocket carrying Langmuir probe was launched on 18th December 1995 at 21:17 LT. The electron density and temperature were measured from the Langmuir probe. This in-situ measurement identify the depletions along the trajectory of the rocket. Together with the density fluctuations, the temperature fluctuations are also noticed. The simultaneous measurements of density and temperature provides insight into the energetics of the spread F phenomena. The two dimensional numerical model is developed to simulate these fluctuations. The model solves the hydromagnetic equations (continuity, momentum, energy and Poisson equations) in a plane perpendicular to the terrestrial magnetic field. The measurements and numerical results are further discussed to understand the energetics of the bubble.</abstract>
