  Observation of interplanetary scintillation (IPS) beyond Earth-orbit can be
challenging due to the necessity to use low radio frequencies at which
scintillation due to the ionosphere could confuse the interplanetary
contribution. A recent paper by Kaplan {\it et al} (2015) presenting
observations using the Murchison Widefield Array (MWA) reports evidence of
night-side IPS on two radio sources within their field of view. However, the
low time cadence of 2\,s used might be expected to average out the IPS signal,
resulting in the reasonable assumption that the scintillation is more likely to
be ionospheric in origin. To verify or otherwise this assumption, this letter
uses observations of IPS taken at a high time cadence using the Low Frequency
Array (LOFAR). Averaging these to the same as the MWA observations, we
demonstrate that the MWA result is consistent with IPS, although some
contribution from the ionosphere cannot be ruled out. These LOFAR observations
represent the first of night-side IPS using LOFAR, with solar wind speeds
consistent with a slow solar wind stream in one observation and a CME expecting
to be observed in another.
