              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
My OU02 observer noticed that their data stopped downloading automatically around 23:10.  They were running a older version of TUI but I had this same thing happen the other night with a different version (latest) of TUI as well. Re-starting TUI completely fixed the issue.  I am wondering if it is a buffering problem backlogging the transfers until they halt.  They were doing a long sequence of 10s ARCTIC exposures.  All data was saved at APO.
Clouds came in enough to cause issues around 04:10.  We gave up at 05:10.
No telescope issues tonight.
