Recent measurements of solar energetic particles (SEPs) by multi-spacecraft fleet at 1 AU in various energy ranges are compatible with a not-vanishing first-order anisotropy in pitch-angle of the particles phase-space distribution. By using an analytic model for the time-dependent perpendicular transport, we calculate the effect of an inhomogeneous magnetic turbulence on pitch-angle anisotropy. We find that the transport coefficient scales differently from previous transport models.
