Avoiding Deep Impact on 2015 of asteroid Apopphis

Gravity wave inducers? Antimatter cannons? Do you really believe we will have these technologies by 2015? Much simpler to explode a few H bombs successively on one side until the asteroids course is changed. Or, if you want something a little more elegant you could attach a solar sail.
