Another glorious hot day in the desert.  Dust devils all over, including one that went right between our storage seatainers.

ISFS staff: Chris, Tony, Will, Justin, me, Isabel and Gary

  • Gary spent time working with hot-film data.  At first, had some data gaps when the LabJack buffer overflowed, but later seemed to work fine.  We might split the digitizing load between two LabJacks, maybe using 2 DSMs if this problem recurs.
  • Most of the crew finished set-up and erected TT.  Mark at the FBO was unconcerned about it as long as it was past the 50:1 glideslope and had a beacon (which it does).  We invited him to visit (hasn't happened yet) and he invited us to his apricot tree (which we did take advantage of!). The TT erection process went well despite our need this time to stop it early.  We just got close and finished up with turnbuckle tension on the guys.
  • Then, most of the crew worked on clean-up and setting up spare sensors (specifically, getting the new CSAT3B wired up – thanks, Tony!).
  • Chris helped Chenning with power for the DTS fiber controller.  Chenning's students will try to pick up a better inverter during a day off in Vegas tomorrow.  Chris is optimistic that, with the right inverter, we have sufficient power for the controller.  If not, we can resort to hand-swapping batteries.
  • Isabel and I worked on burn-in tasks:
    • Made some edits to qctables and co2 limits in project_init that got rid of a lot of false alarms
    • Also hand edited scalar flux groups in stats_5min.xml to get a couple of pressures reporting (but also now has the correct grouping of nanos and sonics)
    • In the afternoon, went to the field with a LARGE punch list and worked through more than half:
      • Soils:
        • Tsoil.t47 had to be replaced (including reinstallation done by hand in the sand).  Strange, but we had a spare.
        • All soils at t23 were working.  Again, stats_5min needed an edit to get most of these running.  Also found an issue calculating Iload/I3load.motes.  Still need to add braid around the cables.
      • TRH:
        • t23 a fuse was missing in the DSM, now working
        • t20 we replaced the housing to get Rfan working
      • Nanobarometers:
        • tried a bunch of stuff to get t47 working (including swapping the nano, DSM ports, cables, etc.).  Concluded that it has to be the internal wiring inside the EC100, so took it down.  This of course also killed the CSAT.
      • Sonics:
        • t27 just needed a serial cable installed.  Done.
        • t26 had the power connector inside the EC100 pulled.  Easy to fix, but then was reporting in ASCII.  Pulled the EC100 and fixed it in the base (probably could have done on the tower using minicom).  Need to reinstall.
        • t21 also needs a serial cable, but we didn't have one long enough – will do tomorrow
        • t10 is an old CSAT3 that isn't reporting at all.  Might return with another data cable and/or open up the box and check power, at least.
        • t9 also was reporting in ASCII.  Again, pulled the EC100, fixed in the base, and will reinstall tomorrow.

Still have some issues at t7, t2, t0, and tt to resolve.

Thanks, everyone for a great job getting M2HATS on track!!  Chris, Tony, Will, and Isabel leave tomorrow.  We celebrate with dinner at the Mizpah tonight.
