There are a couple of reasons to get it off the petals now, and to transfer now. Well, day 3, not right now. Anyway, you don't want to siphon since it'd be a huge PITA to do that. Since it's early in fermentation, you won't oxidize the wort by pouring it now. So, you can pour it into secondary. What I would do is strain though a mesh strainer, or line a colander with a grain bag, to strain out the pulp and petals. I wouldn't even try to use the autosiphon!
