While these bursts aren't as strong as the prior one, because they're coming in on top of them, there will be a cumulative effect. I would expect the A and K indices to go up again as a result but probably not as high. Auroral conditions should continue for a few days depending on what happens with the sun going forward. The large sunspot group producing all of this activity is moving away from the center of the sun's earth-facing side and so we can likely expect things to subside starting sometime Tuesday.
