The Hall D attenuator stopped functioning normally for Ops. Attempts to use the home button were not "normal", the stepper wouldn't return to zero value. On Tuesday DAY shift we'll take convenient access to address, so for rest of OWL had in mind to use the A-laser instead. Decided to take one final attempt w/ D attenuator and able to restore manual functionality.

Ops can now restore beam to 3-halls ~quickly but will adjust the Hall D attenuator manually overnight. I worry if current lock used that perhaps the attenuator will stop working again before morning.
