We combined daily averages of magnetic field vector data and 0.6–1.8 MeV proton angular intensity data to construct 32 pitch angle distributions (PADs) for measurements made by Voyager 1 (V1) at 85–87 AU. The PADs were observed during the period 2002.6–2003.1, when energetic particle instruments on V1 measured unusually high intensities. The angular data show large, mainly unidirectional beaming of protons most often in the −T̂ direction, i.e., away from the sun in the sense of a spiral magnetic field. The mean anisotropy amplitude based on the 32 samples is 0.55±0.21.
