A study of blazar PKS 1424-418 was carried out using multi waveband data
collected by Fermi-LAT, Swift-XRT, Swift-UVOT and SMARTS telescopes between MJD
56000 to MJD 56600 (14 Mar 2012 to 4 Nov 2013). Two flaring episodes were
identified by analysing the gamma ray light curve. Simultaneous multi waveband
Spectral Energy Distributions (SED) were obtained for those two flaring
periods. A cross-correlation analysis of IR-Optical and $gamma$-ray data
suggested the origin of these emissions from the same region. We have set a
lower limit for the Doppler factor using the highest energy photon observed
from this source during the flaring periods, which should be $>$12. The
broadband emission mechanism was studied by modelling the SED using leptonic
emission mechanism.
