Number of positive occultation events in the data set of asteroid occultations, per year. Earlier isolated observations before 1980 are not represented in this plot. We remark here the sharp increase in the number of events starting in 2018 is a consequence of better predictions provided by Gaia DR2 that year. At this point, it is too early to notice if there is a similar trend thanks to EDR3, as we have only recently begun to receive data from those updated predictions.
