Weather: Partly cloudy today, with increasing clouds this afternoon. Cool again with light winds throughout the day. Tomorrow's forecast calls for showers starting in the late morning and lasting through the evening.

Tasking:

• Ned joined us this morning as Andy's replacement for the final 2 weeks of ops. We caught him up on what has changed since he was here last and since there seemed to be no sensor issues we moved on to IRGA and NR01 cleanings. We cleaned all except the IRGA at 1.5-m on lconv, which we will hit another day.
• We swapped out the bad TRH at 10-m on uconv (bad fan and sensor presumably), and rebooted the uconvm DSM at 10:42 CDT. Ned also found that the fan on the 20-m TRH at rel was going bad, so we swapped that one as well. We are down to one spare TRH housing with a working fan.     
• We measured guy tensions and updated the table on the wiki.

Thanks Andy for your help this week!
