1158 is rotating away from facing directly to us so any flares at this
point will not be aimed directly at Earth as the earlier M and X class
flares were.  Actually, I would be more worried if I earned my living in
orbit or at high altitude.  1161 is rotating into an Earth-facing
position but doesn't seem as active as 1158 was though that can change
tomorrow.
