A little after 15:00 MST Dec 5, the TRH at wslope6 failed:

TRH23 -40.21 -3.99 0 0\r\n
TRH23 -40.21 -3.99 0 0\r\n
TRH23 -40.21 -3.99 0 0\r\n
TRH23 -40.21 -3.99 0 0\r\n

Note that the raw values are 0.

I've tried:

eio 5 0
eio 5 1

but it didn't help.

Fog was prevalent all over the valley yesterday, including at 6. We visited the site at 16:15 but didn't notice that the TRH was out.
