              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
We started seeing some horizontal streak in the dcam images starting around image 306.  I believe this is a known issue, just noting it here for the engineering staff.
We had one drive issue, same problem as during my last run. I had things working again in just a minute or two.  Email sent to engineering staff.
I had a dome collision this morning while parking the telescope.  My fault, I sent a command while it was slewing and the drive got upset.  It actually tripped the az drive controller, so I had to turn off the big switch to reset it.  Telescope slewed fine to park position after that.
