  We present high-speed optical observations of the nova ASASSN-17hx, taken
both immediately after its discovery and close to its first peak in brightness,
to search for seconds -- minutes pulsations associated with the convective eddy
turnover timescale within the nova envelope. We do not detect any periodic
signal with greater than $3\sigma$ significance. Through injection and
recovery, we rule out periodic signals of fractional amplitude
$>7.08\times10^{-4}$ on timescales of 2 seconds and fractional amplitude
$>1.06\times10^{-3}$ on timescales of 10 minutes. Additional observations of
novae are planned to further constrain ongoing simulations of the launch and
propagation of nova winds.
