A lightning strike on the afternoon of Sept 27 knocked out power to the base trailer and damaged equipment on the 20m main tower.
In the real-time archive, the DSMs at the main tower ceased reporting on Sep 27 21:03:05 UTC (15:03:05 MDT).
Kurt Kurt restored power mid-morning Sept 28 and we assessed damage to the main tower. Our best guess is that the lightning struck near the base trailer and a current surge flowed down the power cable to DSM M21, trashing the charge controller, the PC104 stack, and the power interface panel. Many of the sensors associated with M21 were found inoperative, but M21 appears to have acted as an expensive 'fuse', limiting damage to M22 and its associated sensors. Gordon wrote:

Two sensors at C also ceased reporting at 21:03:05 UTC: the 1.5m TRH and the barometer. The TRH resumed reporting, all on its own I believe, on Sep 28 04:29 UTC.
