Default Solar flares and the ISS

So with the almost weekly flares and cmes recently, have these posed any
radiation hazard to the astronauts? I've heard little comment about it of
late but presumably as we have had auroral displays and other phenomenons,
the radiation has to be getting through.
also I wonder if any research is being done on this active period in the
suns cycle from the ISS?

well, adding to this, I notice a passing comment on the latest news release
about the Mars new rover that radiation dosing on the way to mars was
quite high, though I noted that the actual levels were not given, so
whatever we do outside the magnetic bubble is going to have to contain an
environment that can be shielded against energetic particles. Maybe we can
use our own magnetic bubble created by superconducting coils powered by a
reactor.

Could run into issues with conservationists, and such, and be all rather
heavy, or big, or both!

It was always my understanding that LEO is a relatively safe place to be
during a solar storm, given the earth's magnetic field. GEO is a far
worse place to be during a solar storm. Also, a very high inclination
orbit would not be as safe due to the radiation and particles coming in
near the magnetic poles.

I'm not 100% sure where ISS fits in as this isn't my area of expertise.
