We can possibly add this to the list of moons that appear to have sub surface liquid oceans. So far, it seems there are liquid water oceans on present on Titan, Europa, Enceladus and possibly, Callisto, Ganymede, Triton and now Mimas. Crazy!
Fortunately, even the relatively thin wall of the Apollo spacecraft would have attenuated the radiation significantly, since the radiation from solar storms is mostly beta:
> The solar storm of August 1972 is legendary at NASA because it occurred in between two Apollo missions: the crew of Apollo 16 had returned to Earth in April and the crew of Apollo 17 was preparing for a moon landing in December.
> Cucinotta estimates that a moonwalker caught in the August 1972 storm might have absorbed 400 rem. Deadly? "Not necessarily," he says. A quick trip back to Earth for medical care could have saved the hypothetical astronaut's life.
> Surely, though, no astronaut is going to walk around on the moon when there's a giant sunspot threatening to explode. "They're going to stay inside their spaceship (or habitat)," according to Cucinotta. An Apollo command module with its aluminum hull would have attenuated the 1972 storm from 400 rem to less than 35 rem at the astronaut's blood-forming organs. That's the difference between needing a bone marrow transplant, or having a headache.

To be fair, they can't actually resolve it at this distance - it's just a dot.
