I have seen it, as a matter of fact two days ago I did see a straight jump
in excess of 1 C. I have seen it before. I do not monitor constantly, but
will keep an eye out.

Frank,
thanks. I can obviously rule out a hand or a body in proximity of the
GPSDO,
as when that happened I was alone in the house and moreover the door was
locked.
I would tend to consider it some sort of glitch either in the firmware or
in the
temperature sensor. I would be curious to know if somebody else has ever
observed
in his Thunderbolt a similar phenomenon.
