About I1 or Oumuamua I mentioned earlier on this thread. 5 times in the last 6 decades, we had 5 celestial objects: one mysterious satellite of earth was widely reported in many telescope viewings form 1956-64 then it vanishes without being seen again. Could be Lilith before it was officially discovered and named, but this one is thought in astrology to produced peak prosperity of the late 1950s-early 60s in the western world and 3 major earthquakes hit the world over M9 on the richter scale: 1957 Kamchatka (Russia), 1960 Chile in South America, and March 27, 1964 on Good Friday in Alaska, USA with great devastation of Anchorage 100 miles from the epicenter. And great comets: Kohoutek in 1973, Halley's approach to earth in 1985-86 and Hale Bopp in 1997-98, both are eras of peak prosperity in the western world (early 1970s, mid 80s and late 90s).
