To indulge in speculation, the only other possible triggers that spring to mind might be the changes in pressure associated with the recent descent and landing, or the very recent temperature changes caused by the opening of the rear cargo doors adjacent to the Aft E&E Bay. Does anyone know the temp at BOS?
BOS Jan 7: Min temp 29F Max temp 39F Mean 34F - at 10:10 I would expect it to be around 32F at a guess. So nothing particularly cold.
