A direct hit with the sun? Maybe slightly higher temperatures if the "impact site" was facing us, but not for long because the sun is highly convective and each "longitudinal ring" on the sun rotates differentially, thus dissipating the effects of that impact very very quickly. A good chunk of it would also probably burn up before even reaching the Sun, but how much of it is hard to say.

But keep in mind, it says "within 11 AU of the Sun", which is still beyond Saturn; Saturn's 9.5 AU away from the Sun, and Uranus is about 19 AU away from the Sun. So it's still pretty far away.
