                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Phones were still out.  Internet was back, but given the uncertainty
 about the generator some essential computers remained down until
 mid-afternoon.  Utility power came back on around 23:30 MT, but the
 generator continued running.
 We had a brief window of an hour or two after sunset when skies were
 clear and humidity was tolerable, but the telescope and instruments
 were still not ready at that time.  Then humidity spiked and low
 clouds and fog moved in.
 The azimuth, altitude, sec, tert, and PMSS all appear to be fine.
 The NA2 rotator is not working properly; Fritz suspected an opto-22
 module might need to be reseated or replaced, and he will check that
 tomorrow.  Most of the instruments and guiders (including fastcam
 and SH) are working and delivering normal images.  The Tspec
 slitviewer kept me occupied for a while but I eventually got it to
 behave with some help from Matt Nelson.  When it was too late to get
 help from Fritz, I realized that I had forgotten Agile; nimble did
 not recover gracefully and needs attention.  So one axis (NA2rot)
 and one instrument (Agile) are still down but the rest look okay.
