  High time-resolution solar wind magnetic field data is employed to study
statistics describing intermittency near the first perihelion (~35.6 Rs) of the
Parker Solar Probe mission. A merged dataset employing two instruments on the
FIELDS suite enables broadband estimation of higher order moments of magnetic
field increments, with five orders established with reliable accuracy. The
duration, cadence, and low noise level of the data permit evaluation of scale
dependence of the observed intermittency from the inertial range to deep
subproton scales. The results support multifractal scaling in the inertial
range, and monofractal but non-Gaussian scaling in the subproton range, thus
clarifying suggestions based on data near Earth that had remained ambiguous due
to possible interference of the terrestrial foreshock. The physics of the
transition to monofractality remains unclear but we suggest that it is due to a
scale-invariant population of current sheets between ion and electron inertial
scales; the previous suggestion of incoherent kinetic-scale wave activity is
disfavored as it presumably leads to re-Gaussianization which is not observed.
