Hello dean, As Stan said, probably about 7.5 minutes for it to start brightening. The ejected material will continue to spread so I suspect it may continue to brighten for hours and possibly days, but the biggest jump in brightness may happen within an hour possibly less. Noone knows for sure just what will happen, however, so that will be the fun of it.
