PT343b at the X-mid went off at about 10:30 hrs. local.  I re-enabled it and it came back on in a few minutes.  John W. contacted Gil Hibbs who was in the X-mid VEA at the time.  Gil didn't think that he was near the area of the gauge.  Perhaps just coincidence.  We have had gauges along the X-arm turn off a few times this year when there was human traffic in the area of the gauge(s) but no causal determination has been shown.  Probably unrelated.  

John and I both got emails when the gauge dropped out but no texts (5 minute threshold for texts?)
