Interesting afternoon: winds at Ken's have been 11m/s (according to ISS1), but at the site have been only 4 m/s (ISS2).  (8m/s at 20m on ISFS towers.)  This over a period of at least an hour.  Must be some exposure at the base and sheltering at the site.  Winds from the SE as I type this at 1518, as a sanity check of wind direction.

Hendrik added some solar panels and power monitor cables.

  • LConv.m now has four panels, previously had three.
  • Rel.m now has four panels, previously had three.
  • Uconv.1, init.b, and init.m now all have power monitor cables.  Steve added these to the XMLs so they're online.
  • (observation) LConv.m likely has enough charging capability, but the battery voltage still seems to drop significantly at night.  More so than UConv.m, which has a similar load.  May be dead batteries.  I'll be watching this over the next couple of days and swap out if needed. 

At 1544 noticed that relm was down.  I think it had been down since about 1130 (before we arrived today).  Hendrik reseated the ethernet cable to put it back on the net.  There are some breaks in the raw_data files, but most data appear to be present.  I've seen this behavior before here, and not sure why the dsms are restarting data collection.

    The DSM restarts data files after USB resets.  That appears to be the case for relm in this instance.  The USB devices all disconnected at 16:44 UTC (11:44 CDT), and while the USB disk recovered and data recording restarted, the ethernet connection did not recover.  Probably Hendrik re-plugging the ethernet cable triggered the re-connection of the ethernet.

    From /var/log/messages, USB disconnects appear to be happening about 3 times per day on this DSM.  Since I don't know what causes these resets, I don't know what can be done to prevent them.
