The 8.2 kiloyear event
When was it exactly in astrological terms?
8200 ya / 72 years per degree of precession = c 113 or 114 degrees of precession ago.
From Aries 0 to Cancer 0 = 90 degrees
114 - 90 = 24 degrees.
The current Cancer 24 (Sirius plus 10 degrees).
That is also the timeline of the Black Sea Deluge. Ballard et al paper indicates that the transition from a fresh water lake to a sea was final c 7500 years ago.
