Aims.We sought to determine the scale of scintillation in the interstellar plasma of PSR J0437-4715.
Methods.We used the Very Long Baseline Array to obtain scintillation amplitude and phase data, from dynamic spectra at 327 MHz.
Results.We observe two scales of scintillation of pulsar PSR J0437-4715, differing by more than an order of magnitude in scintillation bandwidth. The wider-bandwidth scale of scintillation that we observe indicates less scattering for this pulsar than for other nearby pulsars, other than PSR B0950+08.
Key words: turbulence / pulsars: individual: PSR J0437-4715 / scattering
