                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
AzVeloScale: 579.2, 578.0; 578.6 (no change)
First half observer was seeing some evidence that the DIS spectrograph may be out of
focus. Russet logged in to investigate but it was not entirely clear. She will look
into this tomorrow during the day.
Second half observer had a time critical object at the beginning of the shift.
Nimble was locked up. We could not log into it at all, so Nimble was power-cycled.
This resulted in Agile's filesystem not being mounted on Newton. Called Fritz and he
logged in Newton to fix. Anjum was also logged into TUI. There was a lot of
confusion about what needed to be done when Nimble crashes. The AGILE recovery
procedures need to include instructions on remounting the filesystem on Newton.
