I'd wondered whether to ask about that here as it is borderline on/off topic, since I noticed the area marked on the MCC big screen a little while ago. The SAA affects systems like some in the Hubble which are not properly radiation hardened and also other experiments including some flown in the Shuttle payload bay. What effect does it have on communications? One could speculate that radiation could cause noise in receiver front ends - is this the problem or is it something else? Also, does the SAA affect the planning of EVA's? A spacesuit gives even less radiation protection than a Shuttle, I would think.
