Mag 5 +5 Int + 1 initiate (11d6.hits(5)=3) E'yup. Forgot it's mag 6 now, not that it makes a diff.
Don't know if masking helps though, as Xzyl points out. Recognizing the same false signature should still be possible, assuming it is the same false signature every time. Those are some really foggy rules...
As far as I can see it's not always the same, as you have a couple of options: look mundane, make your magic look higher or lower, or look like a different type of creature (although you have to be able to astrally project to look like a spirit or astrally active creature, which adepts cannot).
So it comes down to me knowing if you can do that (I don't think so), me knowing approximately where you are (yes) and finding whatever aura you're currently projecting stange at the location you're in (even a mundane homo sapiens in the ventilation shafts is going to make me wonder, but one wandering in the corridors is not) and me having seen the false aura you're now using before (I have assensed everybody at least once).
So basically I can only see the false aura as I need more hits. Now it's GM's call whether I connect the dots and link the false aura to LJ or not.

You can follow the false aura, its up to kontact where lj went
