We report the low-temperature properties of SrNd$_2$O$_4$, a geometrically frustrated magnet. Magnetisation and heat capacity measurements performed on polycrystalline samples indicate appearance magnetically ordered state at $T_{\rm N}=2.28(4)$~K. Powder neutron diffraction reveal that an \afm\ with propagation vector \QV\ is stabilised below this temperature. The magnetic order incomplete, as only one two Nd$^{3+}$ sites carries significant moment while other site remains largely disordered. presence disordered component N}$ confirmed polarised measurements.
