Dear friends of the See Sat community: Regarding the four COPV´s found in Argentina, I have just received a communication from one of the witnesses who said he spotted the second cylinder on a horse corral around March 20/2025. It completely changes our presumed date of fall. Perhaps it eases the search, hoping some new reentry candidates could fit well with that date. One thing is for sure. The Falcon 9 upper stages carry *three *COPV´s, and we found *four *of them (so far). Cheers.
