I submitted this information from the Carina Software Voyager program Because everyone online seems to think Sothis rises the same day every year at every latitude The date July 20 is Julian and comes from 30 degree GIza and Memphis At 31 degree Alexandria and Ur the absence is 72 days instead of 70 because it can not be seen July 20 and it rises a day later on July 21 Septua Gint means 72 not 70 That s the first fact the rise is pending latitude The further fact is that rise at Memphis is July 17 not July 20 thru the years 2782 1872bc which means in 2782bc the July 20 rise of Sothis on Thoth 1 is already the 4th rising having been seen July 17 on epagum day 3 Thus Thoth 1 must slip back 12 years 3 leap days to be July 17 the first day of rising When information like this is submitted and deleted it is arrogance and wicked heart that does so So i submit no longer and advise many never to donate cash to this cause 98 144 71 174
