On the other hand ,rise time for the first pulse is 0.3770.3 ms, which is faster than2.6478.7 ms measured for large pulses. However the value is similar to the rise time measured for medium and smaller pulses which are 0.4470.37 and 0.337 0.51 ms, respectively , which is comparable to that of 0.64 ms reported by Sharma et al.(2005). Meanwhile the value of FWHMs for the first pulses is 0.6472.00 ms, whereas for large pulses the FWHM was measured to be0.8170.81 ms. Further ,FWHMs for medium and small pulses were measured to be 0.4770.42 and 0.3870.5 ms, respectively . It was found that FWHMs for first pulses are similar to 0.68 ms microsecond scale cloud pulses measured by Sharma et al.(2005) and comparable to0.74 ms measured by Krider et al.(1975) for radiation field pulses from intracloud discharges.
