Analysis of Voyager 1 and Voyager 2 in situ CME observations

This paper studies ICMEs detected by both Voyager spacecraft during propagation from 1 to 10 AU, with observations 1977 1980. are using several signatures in the situ data, primary one being low measured expected proton temperature ratio. We found 21 events common and study their internal structure terms of plasma magnetic field properties. find that expanding as they propagate outwards, decreasing density intensities, agreement previous studies. first carry out a statistical then detailed analysis each case. Furthermore, we analyse case which shock can be clearly spacecraft. The methods described here interesting for other combining data sets heliospheric missions. highlight importance exploiting useful past
