Early Warning and Physics
DSCOVR is meant to study the sun, including solar flares, which feed the Space Weather Prediction Center in Boulder, Colorado. Flares are local to the Sun and do not reach Earth. But very strong flares are sometimes associated with Coronal Mass Ejections (and may cause them; the science is not clear).
The early warning system is not for solar flares but for Coronal Mass Ejections which take several days to reach Earth. These are known to cause blackouts and affect spacecraft.
As far as the isotope anomalies, the science is even less clear. I have heard theories of both massive CMEs and supernovae and there are undoubtedly others floating around.
Hope this helps.
