Yes, the only thing here is that CME's and Flares actually protect us from these neutrons that come in from Gravitational waves. They protect us because they increase the strength of our magnetosphere. Mass extinctions are believed to have occurred from Gravitational Waves when our Sun is at Solar Minimum. Solar max protect us. We are in an prolong solar minimum now as we speak, and the new solar max is expected to come in at 65% less. So if this gravitational wave is intense and long lasting we could be in trouble.
