WebMay 12, 2006 · During equinox periods, September–October and March–April, we found that 50% and 45%, respectively, of CIRs are geoeffective considering intense and moderate magnetic storms, larger then the 33% found when considering all events. For the solstice periods, less than 30% of CIRs are geoeffective, using the same criterion. 4. Conclusions WebThe radial propagation speeds of CMEs have a wide range from tens to thousands of kilometers per second. Thus, the transit time to near Earth's environment [i.e., 1 AU (astronomical unit)] can be as fast as 40 hours to 100 hours.
