We use magnetic field measurements by the Juno spacecraft to catalog andinvestigate interplanetary coronal mass ejections (ICMEs) beyond 1 AU. Duringits cruise phase, Juno spent about 5 years in the solar wind between 2011September and 2016 June, providing measurements of the interplanetary magneticfield (IMF) between 1 and 5.4 AU. Juno therefore presents the most recentopportunity for a statistical analysis of ICME properties beyond 1 AU since theUlysses mission (1990-2009). Our catalog includes 80 such ICME events, 32 ofwhich contain associated flux-rope-like structures. We find that the dependencyof the mean magnetic field strength of the magnetic flux ropes decreases withheliocentric distance as $r^{-1.24 \pm 0.43}$ between 1 and 5.4 AU, in goodagreement with previous relationships calculated using ICME catalogs atUlysses. We combine the Juno catalog with the HELCATS catalog to create adataset of ICMEs covering 0.3-5.4 AU. Using a linear regression model to fitthe combined dataset on a double-logarithmic plot, we find that there is aclear difference between global expansion rates for ICMEs observed at lesserheliocentric distances and those observed farther out beyond 1 AU. Thecataloged ICMEs at Juno present a good basis for future multispacecraft studiesof ICME evolution between the inner heliosphere, 1 AU, and beyond.
