AM, a planet is considered void of course if it has completed the *last* aspect it will make to another planet *while still in the sign it's in*. It doesn't matter (well, there's debate about this, mind you) that it's making several trines, sextiles and quincunxes to planets; we're talking about *applying* aspects from *within its sign* only. Separating aspects don't count; if the moon is at 28 Aries 25 arcminutes, and the last aspect it made was to trine Mars at 28 Leo 18 minutes, too bad - the moon is VOC as it has separated from that trine, assuming no other planets at even later degrees! Applying aspects don't count, either, if the Moon is at 29 degrees Aries and the next aspect it will make is a square to the sun at, say, 2 degrees Leo, too bad; it will only perfect the aspect once it has changed signs - it's VOC. However, in these kinds of aspects, where it's applying to something in another sign by a close orb, some astrologers *do* read this as NOT VOC, but instead implying some kind of imminent change. (Again, refer back to your Medicine thread; Radu has done a very nice job to clarify this point).
Even Lilly didn't adhere entirely to this rule and would use an applying aspect from the next sign, but he was inconsistent in this use, and by and large the majority of the astrological community will agree with the first definition.
Hope this helps.
