Abstract
The solar wind is a continuous flux of charged particles that are ejected from the Sun's atmosphere. The sources of this flux have not been clearly identified yet. Coronal jets are proposed as a possible candidate. They are small collimated ejections of plasma seen in white-light coronagraph images. Using an existing catalogue, a sample of events during the period 2007-2008 was analysed, and ejected particle flux has been estimated. First results are now presented. As future work, all the jets contained in the catalogue will be analysed in order to obtain the average particle flux. The results will be compared to in-situ measurements in order to assess the coronal jet contribution to the solar wind.
