| Abstract : | The three-equation model by Stober & Jacobi (2008) is adapted for lunar atmospheric conditions by neglecting lunar atmosphere density and the drag for deriving the Lunar Impact Flash (LIF) temperatures. This methodology is applied for 55 LIF’s presented in Avdellidou & Vaubaillon, (2019) and drawn the comparison between the temperatures calculated from the model and those obtained from NELIOTA observations. The estimated temperatures of LIF’s using the model presented here are in good agreement with the observed values presented in Avdellidou & Vaubaillon, (2019). The minimum and maximum temperatures estimated are 1292K & 5906K which is within the range of 1275 ± 210K & 5800 ±2800 K presented by Avdellidou & Vaubaillon, (2019). The physical parameters of the impacting meteoroids viz., size, mass, kinetic energy, and luminous energy are estimated for four different values of luminous efficiencies (η). The estimated masses of the impacting meteoroids are comparable with those presented in Avdellidou & Vaubaillon, (2019) while the estimated KE and Luminous energies (LE) are under estimated. The under estimation of the KE and LE may be attributed to the inaccuracy in predicting the velocity of the impacting meteoroids. |
