              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Kosmos values were all missing at checkout.  I did a status all and that brought back the values but then I got a Torrent Error.  I needed to restart the torrent to fix.
High dust and high winds kept us closed.  Dust and wind finally dropped around 22:30 but clouds had came in to replace them.  This wiped out the observations for the first two programs of the night but there is hope alas for the CU class tonight.  Fingers crossed.
Finally opened around 23:45.  Clouds rolled back in and wind picked up at 02:15 and I closed the telescope.
Wind gusts were back up over 40MPH again by 02:45.
We gave up at 04:00
No telescope issues tonight.
