Peace/liberty events basically will always carry the signature of Pallas with her astrological "friends": the Sun, Mercury, and/or the North Node. This signature will appear in the transitory configuration in the heavens as well as in astrological transits etc. for the involved parties. This formula is not easy to spot (hence its non-discovery for two centuries since the discovery of Pallas) but is as consistent as anything I've seen in the discipline of astrology.
I don't have a time for the signing of the treaty, but it's likely to have been around midnight this morning (European time) based on the news stories I've found. Here goes:
