Gordon, Sep 29.
The DSMs on the main tower stopped reporting on Sep 27, 21:03:05 UTC (15:03:05 MDT). This was probably the moment just before the lightning strike.
Two of the sensors at C also ceased reporting at this time:

Id 20,150 is the 1.5m TRH. 20,300 is the Vaisala PTB.
The 1.5m TRH (TRH34) resumed reporting 7.5 hours later on Sep 28 04:29 UTC (Sep 27 22:29 MDT). I believe this was a miraculous resurrection 
, with no human intervention.
This morning three TRHs are reporting at C:
data_dump -i 20,-1 | fgrep TRH 2012 09 29 16:02:03.8064 0.01448 20, 110 35 TRH19 18.57 58.28 0 0 1460 114 0\r\n 2012 09 29 16:02:04.1965 0.005246 20, 250 38 TRH28 17.02 63.57 33 0 1420 125 104\r\n 2012 09 29 16:02:04.2564 0.01515 20, 150 35 TRH34 18.84 56.44 0 0 1468 110 0\r\n
These are the 1m, 1.5 and 2.5 TRHs. The 0.5m is not reporting. From a run of data_stats on the C20_20120928_120000.dat archive file it quit on Sep 28, 14:54 MDT.
