Just because something isn't probable doesn't mean it isn't possible. Given that the "normal" light was still on, either the light logic is faulty or the 5061 never lost lock. That leaves the GPS receiver, antenna and signal path. That it happened at about the time the adjustment was moved could be coincidence.
The probability that it was caused by the Mother Ship hovering over your house and disturbing the signal path is negligible. What else could cause the observed result? Simply losing GPS lock isn't going to make the 1 PPS move around like that. Or were you looking at the received 1 PPS instead of the processed 1 PPS? I don't know enough about the 5061's error logic to know how the 1 PPS could dance around like that. What are the two overshoots at the begin and end of the 100 mS offset straight line? Is that your signal processing or was it real. You don't have any neighbors trying to mess with your mind, do you? Like the guy who secretly added gas to his neighbor's car because the neighbor was so proud of his gas mileage...
