在2002年，旅行者1号太空船位于日光层83.4至85.9 Au（1 Au是太阳到地球的平均距离）之间，日光纬度北纬34度。在2 ~ 16天尺度范围内，该区域观测到的磁场强度剖面具有多重分形结构。在85 Au附近观测到的多重分形谱与40 Au附近观测到的相似，表明在太阳活动极大期附近，随着距离的增加，在遥远的日球层中磁场的多重分形结构演化相对较小。
During 2002, the Voyager 1 spacecraft was in the heliosphere between 83.4 and 85.9AU (1 AU is the mean distance from the Sun to Earth) at 34degrees N heliographic latitude. The magnetic field strength profile observed in this region had a multifractal structure in the range of scales from 2 to 16 days. The multifractal spectrum observed near 85 AU is similar to that observed near 40 AU, indicating relatively little evolution of the multifractal structure of the magnetic field with increasing distance in the distant heliosphere in the epoch near solar maximum.
