  We estimated the coronal magnetic field strength ($B$) during the 23 July
2016 coronal mass ejection (CME) event using i) the flux rope structure of the
CME in the whitelight coronagraph images and ii) the band splitting in the
associated type {\sc II} burst. No models were assumed for the coronal electron
density ($N(r)$) used in the estimation.The results obtained using the above
two independent methods correspond to different heliocentric distances ($r$) in
the range $\approx$\,2.5\,--\,4.5$\rm R_{\odot}$, but they show excellent
consistency and could be fitted with a single power-law distribution of the
type $B(r)=5.7r^{-2.6}$ \textrm{G}, which is applicable in the aforementioned
distance range. The power law index i.e. $-2.6$) is in good agreement with the
results obtained in previous studies by different methods.
