Karl has more information and animations (including the son of lovejoy), here. For previous images, animations and orbit descriptions see this post. Rob McNaught suspects it may not get above magnitude -6 (brighter than Venus but hard to see in daylight). It looks like it may survive to at least perihelion (but then, it will probably spectacularly disintegrate now).
