I noticed a perfectly round ball traveling southbound on 1/24/21 at appt 9:00 a.m. in Mazatlan Mexico. I thought it was a balloon at first but when I realized the wind was going north and the ‘balloon’ was going south that something didn’t make sense so I started videoing it It was moving at a consistent speed about 500’ above the ocean it went in a perfectly straight line from north to south and i video’s until I couldn’t see it any longer
