Is there a technical write up of the false positive? I've long known about Petrov and his intuition, but eventually the error was confirmed and I haven't been able to find much detail as to the "how". Presumably the satellite system that failed had a lab twin, and the failure was reproduced there?

From wikipedia:

"It was subsequently determined that the false alarms were caused by a rare alignment of sunlight on high-altitude clouds and the satellites' Molniya orbits, an error later corrected by cross-referencing a geostationary satellite."
