Caption: Figure 1.

Detection of PSR J0437−4715 with the MWA. The integrated pulse profile (top) and the pulse strength vs. time and pulse phase (bottom) are shown for the 1 hr of observation centered at 192.6 MHz over a bandwidth of 15.36 MHz ("index" on right-hand side of the bottom panel refers to a 20 s sub-integration). Data are de-dispersed, and the residual dispersive smearing within 10 kHz channels is ≈35 μs, smaller than the 100 μs time resolution.
