AB: This paper discusses nine periods of time observed by Wind between 1999 and 2002 when the density of the solar wind plasma fell to values below 1/cc for periods between an hour and a day. All except one of these events could be associated with CMEs, which had plasma moving at about 1400 km/s as it passed 20Rs from the Sun. We suggest that when spacecraft enter rarefactions in this plasma, they observe extreme rarefactions. Thus two coincident conditions, a normal solar wind rarefaction and the arrival of material from an ICME are required for these events to be observed
