                         analysis of characteristics of atmospheric negative 
                         cloud-to-ground discharges through pioneering observations in 
                         Brazil with highspeed camera (Phantom V9.1 model) coupled to a 
                         grism (prism diffraction grid more). Using data obtained with this 
                         system (high-speed camera and grism) was be possible to obtain the 
                         spectrum of the lightning , and thus verify the radiation emitted 
                         by lightning in a range 600-1050 nm. From these observations and 
                         theoretical considerations was possible to estimate changes in 
                         temperature and electron density of the discharge channel to the 
                         stage of direct current and the return stroke (RS). These data was 
                         supplemented by data from the lightning BrasilDAT network in order 
                         to check the values of the current intensity of lightning 
                         estimated by Brasil- DAT. The observations was conducted in the 
                         months of February and March 2014 in the Tower of DCTA (Department 
                         of Aerospace Science and Technology) located in S{\~a}o Jos{\'e}
