Well it takes around 8.3 minutes for light to cross a distance of 1 AU so any light from the Sun will take that long to reach the Earth. No information about the state of the Sun will be available to us sooner than that 8.3 minute barrier. At the macro level where we all live our lives, this way of looking at things holds.
