ResumoCoronal mass ejections (CMEs) are magnetic flux ropes originating in the Sun which are erupted and have the potential to impact the Earth and other planets in the solar system. CMEs are known to be one of the main drivers of Space Weather because they are important sources of out-of-the-ecliptic interplanetary magnetic fields. In the case of the Earths magnetosphere these magnetic fields are the drivers of magnetic reconnection which lead to geomagnetic storms. CME speed estimates near de Sun are made using coronagraph remote sensing images. Several studies have addressed the challenge involved in understanding the dynamics of these eruptive events throughout their evolution in the interplanetary space. The first challenge is to correctly measure dynamic properties of these CME events. Manual measurements are confronted with pseudo-automatic and even fully automatic measurement approaches. It is worth noticing that very few studies have addressed uncertainty estimates for CME speed measurements. In this work, we present a new approach to estimate CME speed uncertainties and we investigate the impact of these uncertainties in the CME travel time to 1 AU of these events.
